following is the relevant failure Quick and problem-solving
computer malfunction causes confusing, elusive. And because the Windows operating system components is relatively complex, computer accident of a failure, for the average user, you absence to needlepoint the reasons for its failure is about impossible. So it is that if we experience computer failure, entirely helpless out? This is not so, the computer-generated though there are many reasons for failure, but if we look carefully, conscientiously amount up, we can still have some computer failures of the statute and approach. In this booklet, we will some of the most common and most typical computer fault diagnosis, livelihood usages show you, through it, you will find - ways to solve computer failure on your side, simple, but effective!
a motherboard
board is a key component of the computer, the computer plays a vital role. If the board will have problems affect the entire PC computer system work. Here, we take a look at the motherboard in the course of which the most common faults.
a common fault: no show boot
microprocessor boot no display, we need to check is the BIOS. Motherboard BIOS the hardware store important file, meantime the motherboard BIOS is part of the more vulnerable, accessible damaged, once damaged it will cause the system can not run, the recurrence of such failures are generally due to the motherboard BIOS is caused by CIH virus damage (of course not rule out the motherboard can not run itself, cause the system to malfunction.) General BIOS hard drive after the virus devastated data will be lost, so we can detect the hard disk data is intact to resolve if the BIOS is damaged, if the hard disk data intact, so there are 3 reasons why the phenomenon of power no display:
1. because the motherboard or expansion card expansion slot problems, leading to plug expansion cards like sound cards, etc. without the display after the embark did not respond.
2. motherboard jumper settings in the CMOS the CPU frequency does not, may also lead to not show fault, which, as long cleared CMOS to be addressed. Clear CMOS jumper on the motherboard usually near the battery, in its default location is 2 short, at a time 3 to alteration it bound a few seconds to solve the problem short, ought the old board for the previous user can not find to the jumper, fair clear the battery, enter the CMOS settings to be displayed after the boot off, will go up also approached the CMOS battery on unload intentions.
3. motherboard does not recognize the memory, memory corruption or memory does not mate the boot no display can lead to failure. Some older motherboards more selective memory, once the plug in the motherboard does not recognize the memory, the motherboard will not start, and even some motherboards do not give you any fault tips (tweet). Of course sometimes in order to expand the memory to improve system performance, plug in the results of different brands, types of memory will also result in the emergence of such a failure, so maintenance should pay more attention.
for the failure of the motherboard BIOS is damaged, we can plug in the ISA card to see whether the display (if prompted, can prompt steps below.), if only the boot screen, you can own do an auto update the BIOS floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try using hot method to solve (I have tried, at a time the BIOS the same, motherboard at the same level can be successful writer.) However, in addition to the use of hot entities, need the same BIOS part of the motherboard components can cause damage, so a authentic method is to write code reader with a BIOS update files will be written inside the BIOS (this service can be to find a safer computer affair solutions).
two common faults: CMOS settings can not be saved
Such failures are generally due to insufficient battery voltage board, which can be replaced, but some motherboard battery replacement also can not solve the problem, at this time There are two possibilities:
1. motherboard circuit problems, which are looking for vocational service;
2. motherboard CMOS jumper problem, sometimes because of the error will jump on the motherboard CMOS line set to clear the option, or set to an outer battery, making the CMOS data can not be saved.
Troubleshooting III: In Windows, install the motherboard driver CD-ROM drive after break or cut corners the phenomenon
in some no-name motherboard sometimes these phenomena occur, the motherboard drivers Bahrain procedure, restart your computer can not enter the Windows 98 desktop in normal mode, and the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers installed, the problem usually can be resolved, if it is not, only to re-install the system.
Troubleshooting four: Install the Windows or start Windows when the mouse is not available
recurrence of such failures because the software is generally caused due to the CMOS settings wrong. Power management settings in the CMOS column has a modem use IRQ project, his options are 3,4,5 ......, NA, generally it is the default option is 3, set it to 3 other than interrupt keys.
Common Fault 5: Frequent computer crashes, during the CMOS settings will crash phenomenon
crash phenomenon occurs in CMOS, usually the motherboard or CPU problem, should the press law does not troubleshooting, it can only replace the motherboard or CPU.
recurrence of such failures are generally due to a problem or motherboard motherboard Cache heat caused by bad design, I had base on the 815EP motherboard is not nice enough for the motherboard heat caused the failure phenomenon. In touch after the crash motherboard components nigh the CPU, found that the temperature is very hot. After replacing the high-power fans, crash failures can be resolved. Cache problem for the failure, we can enter the CMOS setup, the Cache can repair the problem after the ban, of course, Cache weakened, the speed would certainly be affected.
Troubleshooting Six: board COM port or parallel port, IDE interface failure
recurrence of such failures are generally due to causes relative hardware hot plug the user, the user is able to use multi-function card instead of , but must be replaced before the ban comes on board COM wharf and parallel port (some motherboards with the IDE port to be banned for appropriate use).
graphics
common faults one: boot no display
Such failures are generally due to poor adjoin with the motherboard or graphics slot motherboard causing problems. Fjust aboutme integrated graphics motherboard, chief memory if the shared memory, you need to disburse attention to memory location, usually in the first memory slot should be inserted in the memory. As the card causes boot no display failure, power is generally given after a long two short beeps (in terms of graphics for AWARD BIOS).
Troubleshooting II: display the movie, look the clear manuscript
such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to secure mode, under Windows 98 and then into the display settings, the 16-color mode click on the Restart in normal mode Windows 98 system, delete the graphics drivers, restart the computer. Or not to enter safe mode, in a pure DOS environment, edit
SYSTEM.INI file, display.drv = pnpdrver to display.drv = vga.drv after save and exit, then drive in Windows Update
program.
Troubleshooting III: color display is not normal, such failures are generally the following reasons:
1. exhibit card and monitor marker line wrong
2. monitor their own mistake
3. in Some software to scamper while the color is not normal, ordinarily prevalent in older machines, there namely a retard in the BIOS,
GHD Glamour Limited Edition, the color adoptions to open it to
4. Graphics damage;
5. display is magnetized, Such phenomenon is generally due to magnetic objects can be caused by too close after magnetization may also cause screen appears deflection phenomenon.
Fault IV: Death
recurrence of such failures are generally more common in motherboards and graphics cards are not compatible with the graphics card or motherboard is bad; graphics card is not compatible with other extensions can also cause crashes.
Common Fault 5: eccentric noise or screen pattern
such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Need to clean or replace the card fool site was
card.
Troubleshooting Six: graphics card driver is lacking
graphics driver to load and run automatically after a duration of driver wastage, such failures are generally due to poor quality or graphics card and motherboard do not compatible, making the graphics card temperature is too high, causing the system erratic or crash, then only replace the video card.
In addition, there is a special kind of location before to load the graphics driver, but in the graphics drivers loaded into Windows when the crash occurred. Can replace additional types of cards, after loading the driver, insert the old card to be addressed. Should such a failure can not be resolved, then the registry failed, to restore the registry or reinstall the operating system can be.
Troubleshooting a sound card: sound dumb. There are common causes of this failure:
1. Driver default output to Click the bottom right edge of the sound icon (a small loudspeaker), appear to adjust the volume slider, below the
2. sound card collide with other cards. The solution is to modify the PnP cards used by system resources, so that all cards without afflicting each other. Sometimes,
GHD MK4 Pink Straighteners, open the
3. After installing the Direct X sound card can not be aloud. Illustrate this sound card with Direct X compatibility is not good, need to update the driver.
4. one channel silent. Check the sound card to the speaker audio cable is disconnected.
Troubleshooting II: sound card noise is too large. There are common causes of this failure:
1. Card is not correct. As the chassis fabrication precision is not high enough, the sound card manufacturer or installed outside the damper caused by bad sound card expansion slot can not be closely integrated with the motherboard, sound card can be seen visually on the This phenomenon in the ISA or PCI cards are, are common faults. Generally used pliers adjustment.
2. Active speakers Speaker input connected to the sound card output. For the lively speaker, should be connected to the sound card Line out side, it has not been
output signal on the sound card amplifier noise is much smaller. There is only one sound output is still Speaker Line out jumpers on the card depends on the decision, the plant default mode is often Speaker, so the jumper to disconnect the sound card.
3. Windows comes with a bad driver. Sound card driver is installed, select account box. If you have installed the Windows driver that comes with the optional Installation. Then insert the disk or CD-ROM with sound card, load the driver provided by the manufacturer.
Troubleshooting III: Sound can not I once had a sound card under Windows 98 with the original driver disk to install the drivers how can simulate not to, and had to use Creative SB16 driver instead, everything is normal. Later upgrade to Windows Me, not back to normal with Windows 2000 (full edition) comes with the sound card driver was normal.
2. The most difficult problem than the Windows 9X Plug and Play devices under test has chosen to given a free hand to help you install the driver, the driver side is not used, then, each time you erase out reloading will repeat this problem, and can not Here I reveal a secret detached trick: Go to Win9xinfother classify, on the sound card then erase all the *. inf file manually restart the installation after this a hundred percentage effective, have saved countless lives ... ... of course, sound card, modify registration table can accomplish the same purpose.
3. PnP sound card does not support the installation (also applies to not use the PnP mode PnP sound card installed): Go to Windows to search for new hardware?
Troubleshooting four: Play CD silent
1. completely silent. With Windows 98, Use a 4-pin CD-ROM audio cable to connect the analog audio output and sound card CD-in to this line in the buy of a CD-ROM will be included.
2. there is only one channel silent. I generally drive approximately two-wire output signal, the middle two lines to floor. As the audio signal line 4 line color is generally different from the color line to find one to one interface. If only one interface know next to nothing ofund card and audio cable for each interface does not match, had to change the order of the audio cable connection, usually only one of two lines of the change can be.
Troubleshooting five: PCI sound card sonic boom is usually because
Bus Master PCI graphics card with PCI bus technology, resulting in hanging on the hard disk read and write, mouse and other operations to amplify the background
noise's sake. Solution: Turn off the Bus Master PCI card functions, and replaced with AGP graphics card, sound card for the PCI slot.
Common Fault 6: can not properly recording
first check whether there is nothing wrong with the microphone plugged into the other jack in the second, double-click the tiny speaker, elect list see all the settings are correct. Then in the If the
Troubleshooting seven: Can not melodrama melody, Wav, Midi Wav Music
can not play music are quite infrequent, often due to you can disable a; can not play MIDI files may have the following three possible:
1. Early ISA sound card may be due to 16-bit mode is not compatible with 32-bit mode cause MIDI playback is not normal, by installing Software wave chart
way should resolve
2. Today, most of the renowned PCI sound card with wavetable synthesis techniques using, if the MIDI playback is not part of it is probably because you do not have to load the appropriate wavetable sound library.
3. Windows volume control in the MIDI aisle is set to silent mode.
Troubleshooting eight: PCI sound card is not properly used in WIN98
some users complained that the sound card driver installation process everything is normal, no device conflicts occur, but the following is not in the WIN98 out noisy or if there were other failures. This phenomenon usually occurs on the PCI sound card, amuse check the installation process you plug in the PCI sound card which of the PCI slots. Some friends for thermal considerations, like the sound card plug away from the AGP slot, near the ISA slot that several PCI slots. Problems often arise here, because there is a Windows98 Bug: sometimes only the correct identification and inserted in the PCI-1 PCI-2 card slot two. ATX motherboard in two PCI is close to the AGP and PCI-1 PCI-2 (on the inverse in some of the ATX motherboard, close to the ISA is the PCI-1), so if you do not have the PCI sound card installed in the correct slot, the problem will have a.
memory computer memory is one of the most important parts, it is the role of mistrust, the most common memory faults which have it?
a common fault: no show boot
memory because the recurrence of such failure is usually because the memory and the motherboard memory slot is bad cause, as long as tarnish his finger back and ahead with the eraser parts to solve the problem (do not use liquor and other cleaning), there is memory corruption problem or motherboard memory slot can also cause such failures.
Because memory causes no show boot failure, host speakers typically have a long beep (for the Award Bios is concerned).
Troubleshooting two: Windows Registry mar constantly for no cause, users are prompted to restore
such as memory failures are generally caused by poor quality, tough to be repaired, only replaced one way .
Troubleshooting III: Windows often automatically enter the safe mode
Such failures are generally due to the motherboard is not compatible with the memory or the memory caused by poor quality, common in high-frequency memory for Some do not support this frequency of memory on the motherboard, you can try to reduce the memory within the CMOS settings to see whether the read speed to solve the problem, should not do, only replace the memory of it.
Fault IV: promiscuous crashes
such failures are generally due to the use of several different chip memory, due to the memory of different speeds to produce a time difference resulting in decease
machine, which can reduce the memory speed in the CMOS settings to be addressed, only the same type of memory. Another possibility is that memory is not compatible with the motherboard, such phenomenon is generally rare, the other is also possible that contact with the motherboard memory computer random crashes caused by bad. 01
common Fault 5: After the memory to increase system resources, but reduces
such phenomena are generally not compatible with the memories because the motherboard cause, common in high-frequency memory memories fall butme does not advocate this frequency of memories on the motherboard, when such a failure you can try the COMS memory speed will be set by a low point attempt.
Common Fault 6: Run some of the software often prompts
memory of this phenomenon is generally due to insufficient free space on the system disk, you can delete some useless files, leaving some space that is can be generally maintained at
300M or so.
Fault Seven: Install Windows to boot from the hard drive to detect disk space, memory
prompted such failures are generally due to the user in the config.sys file added emm386.exe file, at all times it can block out the problem. CD-ROM drive is
computer hardware accessories in one of the shortest life. In fact, many scrap the drive still has much of value, a little maintenance as long as what you can. This often do not have any progressive knowledge of the radio, do not need anything too complex repair tools and materials. As long as you carefully scrutinize the symptoms and perform the following with reference to some troubleshooting, I trust you can restore the old drive or the old
common fault I: drive when the hard disk light always flashing work
This is an phantom, it is not. Hard disk light flashes because the same drive and hard disk joined to one IDE interface, CD-ROM drive working light also controls the result. Single drive element can be chained to an IDE interface.
Troubleshooting II: In the Windows environment on a CD-ROM when ROM to a certain extent. Most CD-ROM drive connected to the IDE interface is not supported
Windows 32-bit disk way, so that Windows generates an internal error and crashes. Into Windows, the check box to corner off the confirmation, and then restart Windows, in Windows no longer access the CD-ROM into the error will not.
Troubleshooting III: optical drive not properly read the disk, displayed on the screen: ?
In this case, the first detection of viruses, use antivirus software on the machine to check the virus, the virus can not find the file if the editing software to open root directory of C under the CONFIG.SYS if they put up light driver and the driver is creature destroyed, and processing, text editing software can also be used to view problems not found above two steps, removable drive maintenance.
Troubleshooting four: drive to use when prompted to read and write errors or diskless
this phenomenon for most of the disk Shihai there is no place on the drive for operation caused the failure. on the drive all the operations will need to wait for the disc light is like the bit operation only in the DVD player when the time should also be transferred to zero and then changer, so you can avoid the above error.
Fault 5: During the screen when playing VCD movies standstill or break phenomenon
check the AUTOEXEC.BAT file MSCDEX.EXE later on, if so, they should be put
to MSCDEX.EXE SMARTDRV statement before; Party not to use high-speed CD-ROM to rush the program, to SMARTDRV.EXE / U; failure can be ruled out.
Common Fault 6: CD-ROM in the read data, read and sometimes not, and the longer the time to read the disk drive read the disk
no hardware failure is mainly concentrated in the laser head components, and can be divided into two kinds: one is caused by using long laser tube of the old
; the other is the photoelectric surface of the laser lens is dirty or dirty and the displacement of deformation, so the adjustment of laser power, the need for photocell and laser tube lens cleaning.
photocell and focusing lens cleaning method: Disconnect the laser head assembly, a flat cable, remember that intention, open the laser head team chips. Then head to see the jacket covered with laser focusing lens, remove the jacket will find that focusing lens consists of four svelte copper wire connected to the converge, tracing the roll, the optical tube assembly is installed in the bottom of the lens holes in the. with a nice wire mantled in cotton cloth submerged a small quantity of distilled water (not optical tube with an alcohol wipe and focus lens surface), and to see whether the class of the lens of the laser tube is suspended, it shall be adjusted appropriately. Thus, the cleaning is completed.
the laser brain and power in the side of the laser head assembly has a across favor a small screw potentiometer. with color notes under its initial position, generally the premier clockwise 5 ° ~ 10 °, installed No further counterclockwise rotation test machine 5 ° ~ 10 °, until it can successfully read the disk. consideration must not rotate too many, so as not to burn also much power and optical tube.
Fault Seven: boot drive not detected or test failure
This may be due drive data cable connector is loose, damaged or the hard disk drive data cable jumper settings error caused encountered this problem when
waiting, we should first check the CD-ROM data cable connector is loose, if found not plugged in, it will be re-inserted, seated and if this still does not solve the problem, then we got a new data can be put on line to try this time if the fault still exists, we need to check the CD-ROM jumper settings, if there is an error, change it to.
mouse
mouse failure analysis and maintenance is relatively simple, most of the fault for the interface or key contacts bad, broken, filthy mechanical positioning system. a few failures of internal components or circuit Weld mouse, which is mainly found in certain low-quality products, especially in the light-emitting diode, IC circuit damage to the bulk.
a common fault: can not find the mouse
1. mouse completely damaged and need replacement mouse.
2. mouse connected to the host reg code port or PS / 2 mouth exposed, carefully pick a good line, re- can start.
3. motherboard serial or PS / 2 ports from getting damaged, this situation is rare, if this is the case, had to replace a motherboard or a serial port on the multi-purpose card.
4 . mouse line is bad,
GHD Precious Gift Set, this is the most common. bad points more in the mouse inside the cable and circuit board connections. failure is not just another PS / 2 joints, general maintenance it is not difficult, usually due to relatively short lines, or compare the mouse lines are messy and lead to drag hard because the solution is to open the mouse, then use a soldering steel to solder solder. there is a situation that is bad inside the mouse cable is due to long hours result caused by aging, this failure is often difficult to find, replace the mouse is the fastest solution.
Troubleshooting II: the mouse to display, but can not migrate the mouse flexibility
ebb mouse pointer not as dictatorial, but slow, inaccurate positioning, or simply can not be moved. This is mainly because of the mechanical positioning of the mouse scrolling axis in the accumulation of undue sand and lead to transmission failure, resulting in rolling not amenable. maintenance of the internal focus on the mouse X and Y axis on the transmission machinery. The solution is to open the plastic pellet locking plate, remove the mouse ball to roll, with a clean cloth dipped in mild detergent on plastic Ball cleaning, shaft friction can be cleaned using alcohol, preferably a few drops in the axis at the sewing machine oil, but it must be cautious, do not flow to the friction surface and the sew on the grid encoder would be cleared of all dirt, the flexibility to restore the mouse as ever.
Troubleshooting III: the mouse button failure
1. the mouse button without campaign, this may be because the mouse buttons and board too far away from the micro-switch or click on the switch after a period of reduced ability to use the bounce. open the mouse, the mouse buttons below the paste a temperate thickness of plastic film, the thickness is resolute according to actual needs, can be prone of after use.
2. mouse button can not be normal up, this may be because when the key switch in the bottom of the bowl-shaped micro-fracture caused by exposure to membrane, especially the long-term use of plastic is easily broken reed, if a three-button mouse, you can a key that will remove the middle to the emergency, if the original is a good quality brand-name mouse, you can solder, the open micro switch, carefully clean the contacts, some of the grease, the bottles can be used.
Keyboard
keyboard use, failure of performance of a variety of fashions, the causes of many of there bad failure, mechanical failure with their own keys, as well as logic circuit fault, Weld, artificial welding, sealing off the hole oxidation and metal failure. maintenance of omens according to different thinking to determine, find out the cause of the malfunction, make the appropriate repairs.
a common failure: some keys on the keyboard, such as space key, enter key does not work, sometimes, correction shall be entered many times before - one or two characters, and some
key, such as the up cursor key is pressed longer, continuously moving the cursor on the screen, then the keyboard Other characters can not enter, need to press in mandate to gambol
.
this failure to the keyboard new keyboard, the keyboard card key failure is also sometimes occur. a keyboard key to card phenomenon caused by the following two reasons: one reason is that the Caps box under column position offset, making the keycap is pressed and the key body shell stuck the card can not bounce caused by key, for this reason occurred in or near the new keyboard on the keyboard. Another reason is the key long-term use, the spring-elasticity becomes poor, shrapnel and the press wand friction larger, can not make key bounce caused by card key, because this occurred in long-term use of the keyboard when the keyboard key to card failure occurs, can be allocated under the keycap, and then urgent the reception lever. In terms of pole springy not up or fatigue, is caused by the second, otherwise the first cause. If the body shell as keycap stuck with the key causes of put a gasket between the body, some of the gasket can be slightly harder plastic (such as discarded floppy disk jacket) made of, its size is equal to or slightly larger than the key body size, and in the open position by a rod through the ammonium can free rod through the square cavity, it sets in at pole, plug in the keycap; keycap with this gasket to prevent stuck with the key body can mend the fault button; if the spring because of fatigue, the resistance becomes large shrapnel card key causes failure, then the body can be special key to open, a little traction return spring to restore bounce; remove shrapnel will resume key body by removing shrapnel, to depress the resistance by rod bounce, so that the failure to get key the revitalization.
Troubleshooting II: some characters can not enter.
if it were not for one key character can not enter, it may be the key failure or joints Weld. inspection, according to the method described above to open key
panel, contacts with a multimeter measuring the resistance profile of the off state if the key does not always turn on when pressed, then button reed fatigue or bad, in need of repair or replacement; if the key press off when the contacts under normal, indicating that may be due to cold solder coupler, sealing off holes or gold dust due to oxidation, can be measured along the printing line, paragraph by paragraph, identify failure to re-weld; Ruoyin metal hole oxidation and failure can be clean oxide layer, and then re-weld; if completely off the metal hole caused by open circuit, and the welding wire can be connected.
Troubleshooting III: If more than one not in the same column, not in the same line keys can not enter.
may be somewhere in the column line or row line circuit, or logic doors may have problems. 100MHz when used to detect high-frequency oscilloscope to find the device Weld failure point, and then repair.
Fault IV: keyboard input and screen display of the symbol is incongruous.
such failure may be due to short circuit the circuit board caused by the phenomenon, its performance is based on The key is shown as the same as the other characters, this time can be amounted multimeter or oscilloscope to determine the point of failure after repair.
Common Fault 5: Press a button produces a string of multiple characters, or button when the characters bounce.
This phenomenon is caused by the logic circuit fault. first select a column of characters, if the Enter key a row without a column, may generate the phenomenon of a number of other characters ; if the one with the Enter key, will have a bounce and can not be the last character of the phenomenon into the system, check with an oscilloscope logic circuit piece, the chip to find fault with the model after replacing the new chips, troubleshooting.
Modem
Changjian fail-: 56K is not on the Modem to 56K. This problem can be from the following considerations:
1. the actual 56Kmodem can only reach maximum speed of 53K just about, to consider the assorted effects, 56Kmodem speed generally between 45-53K.
2. Modem tel line to a large extent inspire the transportation rate, if poor quality tel lines, line voltage instability, 56K Modem
on the last of less than 56K; Another use of the Internet extension will also affect Internet speed.
3. not installed the correct driver.
4. and ISP with assorted protocols, only your Modem and your ISP approval is the same, Modem will to 56K standard.
preclude the above reasons, your 56K Modem is still much faster than 53K, this is your Modem hardware problems can be considered a replacement or repair
.
common Fault 2: Modem often dripped, resulting in dripped phones there may be several reasons:
1. poor quality tel line;
2. If the data terminus prepared (DTR) signal is invalid duration Over Modem default settings, it will cause dropped;
3. If your call has a open;
4. In addition, Modem their quality and compatibility problems between different Modem Modem is caused by a common cause of dropped calls.
Troubleshooting III: Modem no dial tone
When the Internet in the die of night, in order to make the dial tone does not affect the others sleep, through the proper AT command to change: You can use the ATM0 set Modem no dial tone, and ATM1 set Modem from dial-up connection for a dial tone For volume selection you can change the following instructions, ATL0 (low volume), ATL1 (low volume), ATL2 (in volume), ATL3 (high volume).
Troubleshooting four: do not fax speeds up to to 14400
Modem maximum fax rate is 14400, and fax only when the rate of 9600. This is because most of the fax machine to send and receive rates are
is 9600, and only use the rate of 14400 or 33600 fax, Modem fax speed will reach 14400.
Common Fault 5: Modem can not dial or connect
If not properly installed on your Modem, communication will not work. The following lists the authentication process with the Windows Communication Modem installed an incompatible driver files, may lead to the COM port and Modem not working properly, so you should first check whether the correct Windows98 loaded file.
1 test existing communication file
(1) the System catalogue COMM.DRV and SERIAL.VXD file with Windows95 floppy disk or CD-ROM in the elemental file to compare, check
check the file size and date are the same.
(2) to confirm the System.ini file in the emulating lines: [shoe] Comm.drv = Comm.drv [386enh] device =* vcd
(3) In the Run ini is also not related with
* VCD files These files are built in VMM32.VXD in.
2.
test your modem configuration in the , press the options, set the maximum baud modem support, and click .
4.
check the correctness of the port in the br> listed ports are correct. If not, please select the correct port, and then click The new resource settings, see your modem manual to find the correct settings in the conflict with other devices, click the
use the same kind of IRQ, and in most computers can not be used. COM2 and COM4 have the same problem, if possible, change the COM3 and
COM4 port IRQ settings, so that they no longer clash. In addition There are also some display cards and COM4 port residence conflict, if conflict found, please use other ports, or replace your graphics adapter.
6.
test port settings in the Double-click the experience.
7.
modem baud rate test in the wave
special rate is set to the correct rate.
Note: If you call the main system in the original set baud rate can not communicate, then sometimes lower baud rate may solve the problem.
printer
in the bureau, the inkjet printer is to use it in a more general kind of equipment the use of inkjet printers, maintenance, unsuitable operation and other factors often will be some failures, how to resolve user concerns. Here we put daily work and treatment of common faults summed up, we want to aid.
common faults one: printing ink scarce, indistinct penmanship processing, most of the fault is due to the long-term unused or printer other reasons, resulting in the ink distribution system disorders or nozzle clogging.
exclusion: If nozzle clogging was not very mighty, then the printer instantly to fulfil the cleaning operation can be, if no effect after reiterated washing, you can obtain the cartridge (one for non-printer cartridge nozzle, the nozzle needs to obtain,
GHD Straighteners NZ, but need to carefully), put the nozzle in warm water drench for a while, attention must not be part of the circuit board is also submerged in water, or another , tainted with absorbent periodical to take away the water droplets, and then cleaned several times mounted on the nozzle on it.
Common Fault 2: Replace the print cartridge, printer in the boot plate processing
normal circumstances, when the ink has run out when the yes cartridge may not installed, the other may be turned off in their own Naxia old cartridge, replace the ink cartridges on the new, because to replace the print cartridge, printer ink delivery system will Jinxing filling ink, and this process in will not be turned off, making the printer can not detect the re-install the cartridge. In addition, some printer ink capacity of the calculation is to use the printer's internal electronic counter to count (especially in the color of ink used for the statistical ), when the counter reaches a certain value, the printer ink is used to determine, while in the process of replacement cartridges, the printer will behave its internal electronic counter reset, thus confirming the installation of a new cartridge.
solution : Turn on the power, the print head moves to the ink cartridge replacement position. the cartridge is installed, get the printer to dictate the ink, ink charging process is complete, troubleshooting.
Troubleshooting III: soft plug of the nozzle processing
soft plug plug refers, for various reasons on the viscosity of the ink in the nozzle due to crash bigger fault. general use original ink cartridges can be recovered after repeated washing, but this way too many to consume ink. The easiest way is to use your hands blank cartridges for nozzle cleaning. with an empty cartridge cleaning before it gets inside the cartridge with a needle to extract the residual ink as possible, the detergent the better, then increase the cleaning solution ( Accessories commercially available). filling cleaning liquid should be in a clean environment, will join a good cleaning fluid cartridge according to the normal operation of the printer machine, printer cleaning by key continually be cleaning. using ink remaining in the ink and light colors merged cleaning fluid test print, then put on a good normal cartridge can be used.
Troubleshooting four: Clean the pump nozzle printer troubleshooting
printer cleaning pump nozzle go bad are more, and also contributed to plug a important element in The printer is cleaning the pump nozzle on the print head protection played a crucial character. Pentou car back to the bit, up to the pump nozzle cleaning the exhaust of 喷头 the feeble manipulation of the Pentou seal protection in the printer or install a new ink cartridge nozzles are disconnected, the suction pump to the base of the machine via its exhaust nozzle, the higher the better precision of the work of the mouth, but in tangible use, its representation and tightness due to the enhancement of time, dust and ink residues in the mouth of the condensate increases. If the user does not inspect or wash it regularly, it will keep you out of some of the publish head failure.
maintenance of this part of the method: Remove the printer cover away car, using a prod wash them inhaling pure water, of special note, embedded within the pores of the mouth to fully clean the gasket at this to caution the user , cleaning the parts, do not use ethanol or methanol to clean them, this will cause this component liquefied in the mosaic of the porous gasket distortion. Also to advert is that inkjet printers should be kept away from heat and dust work environment, only a good working environment to ensure long-term normal use of the machine.
Common Fault 5: normal and printing ink line observation accuracy was significantly worse treatment
inkjet printer in use will the use of frequency and timing of the extension of the gradual deterioration of printing accuracy. ink-jet printer head is also a life. general use from the starting of a new nozzle to the end of life, the more smoothly if you could not see any fault, then, is 20-40 the amount of life one cartridge if your printer has been used for a long time, now print less accurate, you can use the method of replacement ink cartridges to try, if for a few cartridges, print output results are the same, then you this printer's head will be replaced if there is a change after the replacement ink cartridges, indicating the possible use of the cartridge you have poor quality non-original ink.
If the printer is new, print the results can not satisfy you , often printed line is not clear, skewed text graphics, text, graphics appearance the boundaries blurred, print out the ink control synchronization accuracy, this manner you may buy a counterfeit ink cartridges or use non-original productions, it should be replaced swiftly.
Common Fault 6: meet dislocation trolley treatment
inkjet printer trolley alley along two sets of abrasive alloy of copper with a circular shaft to slide with complete precision While walking there is a small car designed and installed to accessory the shaft lubricating fuel Felt, but the environment we live in the dust everywhere, over period, due to ventilation oxidation, dust damage to the surface of the oil aging axis The failure, then if it continues to use the printer, will be due to shaft friction increases with the copper sleeve to wade dislocation caused along the car until the collision caused the front can not be accustomed.
solution is: Once this failure should immediately turn off the printer, will not hand back the car back into place parking spaces. to find a small piece of absorb or felt, sewing machine oil on the cake dipped oil, forceps rub back and forth on the spindle, preferably to spindle removed, washed and oiled, so that the best results.
meet variant car because of damage caused by the device. printer car parking spaces on the top of a photoelectric sensor, it is the motherboard to printer print reset signal to invest a key makeup of the car. If this component is too massive or damaged due to dust, the printer will not find a car back to digital signals across the front,
GHD Hair NZ, but unusable, usually out of the failure to replace the device.
Display
a monitor for a long time, and a variety of small problems would follow. specialists believe that to solve these little problems is really very simple, with a couple of eyes can see where the fault.
a common fault: just getting on the computer screen of machine vibrate badly, and sometimes even the icons and text is also not clear, but after twelve minutes and then will return to normal.
This phenomenon in rainy weather is damp inside the monitor's sake. To solve this problem, the use of edible packaging in the damp dirt with cotton string attach, then open the display back cover, damp sand in the CRT tube cervix hung the tail close to the tube near the seat so namely even in rainy weather, will not seem above the one. to await several minutes afterward to seem on the screen.
seat tube leakage is due to be replaced tube socket. open the back cover to see the end of the tube a small circuit board, tube socket the weld on the circuit board
Carefully unplug this circuit board, and then welded pipe under the seat, to the electronics store to buy back a seat the same tube, seat tube and then welded back on the board. At this time not to rush the board and putting it back to first find a small piece of sandpaper, very carefully after the end of the tube protruding pin wipe clean with sandpaper, especially pay attention to pin on the oxide layer, if I were you clean and very lustered will immediately relapse. the board back together and you're done.
Troubleshooting III: there is all staying on the display screen clutter interference or lines, but spokesmen also have unpleasant noise.
This phenomenon is mostly due to poor power supply interference if too idle to get involved, you can replace a new power supply if there are enough hands to
coerce, you can try to replace the power within their own filtering capacitor, which often can be forcible; if the result is less apparent, can be replaced
switch to.
Common Fault 4: display Huaping.
this problem more caused by the graphics card if is new for the graphics card, the card may be of poor quality or conflicting, then there is by far installed the correct drivers and if the old card and added memory, then there may be additional new graphics and original memory varies due to model parameters.
Common Fault 5: display a black screen.
display if the video card is damaged or broken and so causes no signal sent to the display, the display light will blink tips merely no reception. If the resolution is set too tall, more than the maximum resolution the display will appear dark, caustic dispose of the display, yet immediately the display has protection function, when the resolution exceeds the set value is automatically protected. In addition, hardware conflicts can cause a black screen.
display jitter causes
display refresh rate is set too low
when the monitor refresh rate is set below 75Hz, the screen will appear often shake,
GHD MK4 Gold Straighteners, flicker, the refresh rate to increase due, for example, set higher than 85Hz, the screen jitter phenomenon generally will not occur repeatedly.
power transformer from the chassis too close
display and power transformer will result in greater electromagnetic interference, resulting in screen jitter. away from the power transformer chassis and display areas, the problem can be solved.
bad power supply or power supply has many aging
used brand-name computer power supply components work, matters are quite poor, could easily lead to computer poor aptitude to keep up or power circuits, when the system is engaged, the display screen will appear, primarily the phenomenon of jitter. computer's power supply started aging, are promising to cause the same problem.
put enough away from the speaker monitor speakers too close to the magnetic field effect
interfere with the normal operation of the monitor, the monitor screen jitter and produce magnetic interference such as cross color phenomenon.
virus trouble
some computer viruses will disunite the display, such as: the character upside down, shake the screen, graphics, flip display. everywhere online screen jitter script, enough to make you move in after the head as big as a cow.
bad graphics card
re-inserted card, the obtainable fault exclusion.
WIN95/98 system write cache causing
such as belonging to this reason, in the Control Panel - System - Performance - File System - Troubleshooting disable all drive write-caching, allowing the problem to be solved.
power supply percolate capacitor damage
open the circumstance, if you see the power supply filter capacitor ( the biggest children in the circuit board capacitor) at the top of muster, then it shows bad capacitor, and the screen jitter caused by power failure. After the change of capacitance can solve the problem.
burner
Troubleshooting 1: Install the burner does not start after computer
First off the computer power supply, open the case cover check IDE cable is fully inserted, and to ensure that PIN-1 position of the pin is connected correctly and if the recorder and other IDE devices sharing an IDE cable, the need to ensure that two devices can not be set to >
Troubleshooting II: the success of using analog recording, the actual recording but failed
burner provides identical
, that is, and burner laser power and disc read-write head matches, etc. In view of this, that using the following two methods to re-try it:
1. reduce the burner write speed, 2X recommended the following;
2. replace another mark of blank discs for burning operations. there's another phenomenon One reason is that the laser power attenuation caused by read-write head, and if you use the same brand of disc recording, the first time were normal, then it may be related to the power attenuation of the read-write head can be sent to the vendor maintenance.
Troubleshooting III: Unable to copy the game CD
some large-scale mercantile software or game software, in the production process, the CD-ROM record apt do to defend, so during the CD duplicate process, will there tin no be copied, resulting in the burning process the error occurred, or not work behind copying apt happen.
Common Fault 4: a burned CD music does not play
not always audio devices able to read normal CD-R disc, and most CD players can not properly read the contents of CD-RW disc, so it is best not to use CD burner to burn music. Also, note that the burn CD music, CD-DA must meet the file format.
Troubleshooting five: the process of CD burning software to burn, sometimes message means for the buffer underrun, normally in the recording process, data needs to be burned off by the hard disk by
transmitted to the host IDE interface, and then transmitted through the IDE interface to the recorder's cache (BufferMemory), the last recording machine to store the data in
BufferMemory in recording message onto CD-R or CD-RW disc, these deeds must be continuous, must not be interrupted, if any one part of a problem, will not cause burner normal write data, and the emergence of a buffer underrun error, then the disc scrapped. The solution is, before the burning need to close some of the memory-resident programs, such as turn off CD automatic insert notice, turn off your antivirus software, Window task management and mission scheduler and screen saver, and so on.
Common Fault 6: CD burning process, they would often burn burn failure
cultivate the success rate of a simple need to preserve the system environment, ie turn off backdrop dweller program, it is best to prepare for the recording system, a devoted hard drive, specifically related to software installation and burning in the burning process, it is best to first retention the data on the hard disk, made into and then on CD-ROM. In order to ensure flat data convey recording process, requiring constant arrange of disk fragmentation, files can not be shirked due to the normal transmission, the error interruption caused by the burning, you can perform mail a message to the local staff, will affect the burn effect, In addition, the LAN, do not use resource sharing, if the burning process, the other users to read the local hard disk, will cause disruption or failure of recording work. In addition, even
Repair computers, - yourself .
