The following are related fault speed investigations and solving problems

The causes of faults in computers are confusing and elusive. And because the components of the Windows operating system are relatively complicated, once the computer fails, for ordinary users, it is almost impossible to accurately find the reason for its failure. So does it mean that if we encounter a computer failure, we are completely helpless? In fact, this is not the case. Although there are many reasons for the failure of the computer, as long as we observe and summarize it carefully, we can still master the laws and processing methods of some computer failures.在本期的小册子中，我们就将一些最为常见也是最为典型的电脑故障的诊断、维护方法展示给你，通过它，你就会发现——解决电脑故障方法就在你的身边，简单， But effective!

. The motherboard

The motherboard is the key component of the entire computer, which plays a vital role in the computer. If the motherboard fails, it will affect the work of the entire PC system. Below, let's take a look at the most common faults during the use of the motherboard.

Copic fault 1: No display

The computer booting without display. First of all, what we want to check is BIOS. The main board's BIOS stores important hardware data. At the same time, BIOS is also a relatively fragile part in the motherboard, which is very vulnerable to damage. Once damaged, the system will not run. (Of course, it is not ruled out that the motherboard itself fails to run the system.). Generally, the data in the hard disk after being destroyed by the virus will be lost, so we can determine whether the BIOS is destroyed by testing whether the hard disk data is intact. If the hard disk data is intact, then there are three reasons that will cause the phenomenon not displayed without display: :

1. Because there is a problem with the motherboard extension or extension card, the motherboard after the expansion card such as sound card is not responded without display.

2. The CPU frequency set in CMOS in the CMOS is wrong, and it may cause no failure. In this regard, as long as the CMOS is cleared, it can be solved. Clear CMOS jump lines are generally near the lithium battery of the motherboard. The default location is generally 1 and 2 short circuits. As long as it is changed to 2 or 3 short circuits, it can solve the problem. By the jump line, as long as the battery is removed, it will be displayed after the power is settled and turned off after the CMOS settings.

3. The motherboard cannot recognize memory, memory damage or memory does not match, and it can cause no display failure. Some old motherboards are relatively picky about memory. Once the main board cannot be recognized, the motherboard cannot be started, and even some motherboards will not give you any fault prompts (tweet). Of course, sometimes in order to expand the memory to improve the system's performance, it will also cause such faults to plug in different brands and types of memory. Therefore, pay more attention during maintenance.

For the failure of the motherboard BIOS, we can insert the ISA graphics card to see if there is a display (if there is a prompt, you can follow the prompt step to operate.), if there is no turning screen, you can do it yourself yourself一张自动更新BIOS的软盘，重新刷新BIOS，但有的主板BIOS被破坏后，软驱根本就不工作，此时，可尝试用热插拔法加以解决（我曾经尝试过，只要BIOS相同，在The motherboards at the same level can be successfully recorded.). However, the use of the same BIOS with the same BIOS may cause damage to some components of the motherboard. Therefore, the reliable method is to write the BIOS update file into the BIOS with the code writer (it is safe to find a computer dealer with this service).

Copic faults: CMOS settings cannot be saved
This is generally caused by insufficient main board battery voltage, which can be replaced, but some motherboard batteries cannot solve problems after replacement There are two possibilities at this time:

1. Motherboard circuit problem, you need to find professionals for maintenance;

2. Motherboard CMOS jumper problem, sometimes because of errors because of errors Set the CMOS jumper on the motherboard to the removal option, or set it to an external battery, so that the CMOS data cannot be saved.

Copic fault three: The phenomenon of slowing or light -driven reading on the motherboard driver under Windows becomes slower. After installing the motherboard driver, the computer cannot enter the Windows 98 desktop in a normal mode, and the driver cannot be unloaded under Windows 98. If this happens, it is recommended to find the latest driver and reinstallation.

Copic fault 4: Install Windows or start Windows, mouses cannot be used

The software for such faults is generally caused by CMOS settings errors. There is a MODEM USE IRQ project in the power management column set by CMOS. His options are 3, 4, 5 ......, NA, respectively. Generally, its default options are 3. Just accept it.

Copic fault 5: Computers frequently crashes. When setting CMOS settings

The crash phenomenon in CMOS. Generally, there is a problem with the motherboard or CPU. Pressing the method cannot solve the failure, then only the motherboard or CPU is replaced.

This such faults are generally caused by problems with the motherboard cache or poor heat dissipation in the motherboard design. The author has found on the 815EP motherboard that the motherboard is not good enough to cause the fault. Touch the main board component around the CPU after the crash, and it is found that its temperature is very hot. After replacing the high -power fan, the crash failure was resolved. For CACHE's problems with problems, we can enter CMOS settings, and can solve the problem smoothly after the cache ban is prohibited. Of course, the speed of Cache will definitely be affected after the ban.

Copic fault 6: Motherboard COM port or parallel port, IDE port failure

This such faults are generally caused by the user with electricity plugging and pulling related hardware. At this time, users can use it. The multi -function card is replaced, but before replacing the comes with the COM port and parallel port on the motherboard (some motherboards must be prohibited to use normally).
graphics cards
Copic failure: No display

This is generally caused by poor contact with the motherboard or motherboard slot. For some motherboards with integrated graphics cards, if the video memory shares the main memory, it is necessary to pay attention to the position of the memory bar. Generally, there should be a memory bar on the first memory slot. There is no display failure caused by the booting of the graphics card, and a long or two bee sounds are generally emitted after turning on (for the Award Bios graphics card).

Copic faults 2: Display flower screen, cannot see the handwriting

The faults are generally caused by the display or graphics card do not support high -resolution. When the flower screen, you can switch the startup mode to the security mode, and then enter the display settings under Windows 98, and click the "Application" and "OK" button in 16 colors. Re -start, delete the graphics card driver in the normal mode of the Windows 98 system, and restart the computer. You can also not enter the security mode. In the pure DOS environment, edit
system.ini files, and change the display.drv = pnpdrver to display.drv = vga.drv. driver.

Copic fault three: The color display is abnormal. Such failures generally have the following reasons:
1. Poor exposure to the graphics card and the monitor signal line
2. The display itself of it r r
3. The color is abnormal when running in certain software, which is generally common in old -fashioned machines. There is an option to check the color in BIOS. 5. The display is magnetized. Such phenomena are generally caused by excessive closeness to objects with magnetic properties. After magnetization, it may also cause a deflection of the display screen.

Copic fault 4: crash

This such faults are generally common in the unsatisfactory of the motherboard and the graphics card or poor contact with the motherboard and the graphics card; Causes crash.

Copic faults: abnormal miscellaneous points or patterns appear in the screen

This is generally caused by the input of the graphics card or poor contact with the motherboard. Need to clean the graphics card gold finger part or replace the display
card.

Copic fault 6: Lost of the graphics card driver

In the graphics card driver is loaded, and the driver is automatically lost after a period of operation. The graphics card and the motherboard are not compatible, making the temperature of the graphics card too high, which causes the system to run unstable or crash. At this time, only the graphics card is replaced.

It, there are a special case. In the past, the graphics card driver could be loaded, but after the graphics card driver was loaded, it fell when entering Windows. After loading its driver in other types of graphics cards, the old graphics card can be replaced. If such faults cannot be resolved, the registry failure can be explained, and the registry can be restored or reinstalled the operating system.
Sound card
Copic failure: Sound card silent. The common causes of this failure are:

1. The driver is output as "mute" by default. Click the sound icon (small cough) in the lower right corner of the screen, and the volume adjustment slider appears. There is a "mute" option below. Click the check box in front to clear the sign in the box to pronounce normally.

2. The sound card conflicts with other plug -in cards. The solution is to adjust the system resources used by the PNP card so that each card does not interfere with each other. Sometimes, "Equipment Management" is opened. Although the yellow exclamation mark (conflict sign) has not been seen, the sound card is not sounding, but there is actually a conflict, but the system has not been checked.

3. The sound card after installing x is installed. It shows that the compatibility of this sound card and Direct X is not good, and the driver needs to be updated.

4. A channel is silent. Check whether the audio cable from the sound card to the speaker is disconnected.

Copic fault two: The noise emitted by the sound card is too loud. The common causes of this kind of failure are:

1. Inserture cards. Due to the insufficient accuracy of the chassis and the poor sound card baffle manufacturing or installation, the sound card cannot be closely integrated with the motherboard extension slot. The visible "golden finger" on the sound card is misplaced with the expansion slot reed. This phenomenon is on the ISA or PCI card, which is a common failure. Generally can be used to correct with pliers.

2. The Speaker output terminal connected to the sound card. For active speakers, it should be connected to the LINE OUT end of the sound card. The signal it outputs
has not passed the amplifier on the sound card, and the noise is much smaller. Some sound cards have only one output end, whether LINE OUT or Speaker depends on the jump on the card. The manufacturer's default method is often Speaker, so you need to unplug the sound card to adjust the jumper.

3. The driver comes with Windows is not good. When installing the sound card driver, select "Driver provided by the manufacturer" instead of
"Windows default driver" if you install it in a "adding new hardware", you should choose "installation from the disk" instead of Select from the list box. If the driver comes with Windows has been installed, the "control panel → system → device management → sound, video and game controller" can be selected, each sub -device, select the "attribute → driver → change the driver → from the disk Install". At this time, the disk or disc paired with the sound card is inserted into the driver provided by the manufacturer.

Copic fault three: sound card cannot "plug and play"

1. Try to use the new driver or replacement program as much as possible. I used to have a sound card. Under Windows 98, I could n’t install the driver with the original driver disk. I had to use the Creative SB16 driver instead, everything was normal. Later, it was upgraded to Windows ME, and it was not normal to change the sound card driver with Windows 2000 (full version).

2. The most headache is the detection of plug -and -play device under Windows 9X, but it is self -made to help you install the driver. This driver cannot be used. If you delete the reinstallation, you will repeat this problem, and you cannot solve the method of "adding new hardware". The author leakes a unique trick here: enter the directory, delete all the * .inf files about the sound card and then start it manually. This is a 100 % spiritual inspection. It can also achieve the same purpose.

3. Installation of PNP sound cards (also applicable to PNP sound cards that cannot be installed in the above PNP method): Enter "control panel"/"add new hardware"/"next step", as prompts as prompts "Do you need Windows to search for new hardware?", Select "No", and then select "Sound, Video and Game Controller" from the list to install it with a drive disk or directly select the sound card type.

Copic fault four: Play CD silently

1. Put the CD silently with the "CD player" of Windows 98, but the "CD player" is working normally, which shows that the audio cable of the optical drive is not connected. Use a 4 -core audio cable to connect CD -ROM analog audio output and CD -I in the sound card. This cable will be attached when purchasing CD -ROM.

2. There is only one channel sound. The output port of the optical drive generally has two signals on the left and right lines, and the middle two lines are ground lines. Because the 4 lines of the audio signal line are generally different, the corresponding interface can be found from the color of the line. If there is only one interface on the sound card or each interface does not match the audio cable, you have to change the wiring order of the audio cable, usually only the two lines can be replaced.

Copic fault 5: PCI sound cards appear explosive

generally because the PCI graphics card uses Bus Master technology, it is enlarged by the hard disk reading and writing, mouse movement and other operations hanging on the PCI bus. Background
This noise. Solution: Turn off the Bus Master function of the PCI graphics card, replace it with an AGP graphics card, and change the PCI sound card to the slot.

Copic failure 6: Can't recording normally

Ploped to check if the microphone was inserted into other jacks. → Recording "to see if the settings are correct. Next, the "mixed device" and "line input equipment" are adjusted in "Control Panel → Multimedia → Equipment" and set them to "use". If the "recording" option in "Multimedia → Audio" is gray, it is bad. Of course, it is not no room for saving. You can try the "ISA Plug and Play Bus" in "Add New Hardware → System Equipment". , Simply start the sound card with the card tool software.

Copic fault seven: cannot play WAV music, MIDI Music

This WAV music phenomenon is rare, often due to "multimedia" → "audio equipment" under "equipment" "Not only one, just disable one; the MIDI file cannot be played:

1. Early ISA sound card may be due to the 16 -bit mode and 32 -bit mode. Not normal, the
method of installing the software wave table should be able to solve

2. Most of the popular PCI sound cards today use wave table synthesis technology. You do not load the appropriate wave sound library.

3. The MIDI channel in Windows volume control is set to be mute mode.

Copic fault eight: PCI sound card uses abnormally under Win98

It users report that everything is normal during the installation of the sound card driver, and there is no equipment conflict, but in the past Win98 below is unable to make a sound or other faults occur. This phenomenon usually appears on the PCI sound card. Please check which PCI slot you inserted PCI sound card during the installation process. Some friends like to insert their sound cards away from the AGP slot and near the ISA slot near the ISA slot. The problem often appears here, because the Windows98 has a bug: sometimes it can only correctly identify the sound card that is inserted in PCI-1 and PCI-2. The two PCIs that are close to AGP on the ATX motherboard are PCI-1 and PCI-2 (just on the opposite of some ATX motherboards, PCI-1 is close to ISA), so if you do not install the PCI sound card on the right correct On the slot, the problem will occur.
memory

M memory is one of the most important accessories in the computer. Woolen cloth?

Copic failure: No display

The cause of memory bar. Such failure is caused by poor contact with the motherboard memory slot. Try its golden finger parts to solve the problem (do not use alcohol and other cleaning), and there is a problem with memory damage or motherboard memory slot, which will cause such faults.
The no display failure caused by the instrument of the memory, the host speakers generally have a long time of bee (for Award Bios).

MST: Windows registry is often damaged for no reason. It is prompted that users are required to restore

This is generally caused by poor memory quality and it is difficult to repair it. Only replace it.

Copic fault three: Windows often automatically enter the security mode

This is generally caused by the inadequate compatibility of the motherboard and memory or memory bar, which is common in high frequency The memory is used on the motherboard that does not support this frequency memory bar. You can try to reduce the memory reading speed in the CMOS settings to see if it can solve the problem. If not, you can only replace the memory bar.

Copic fault 4: Random crawling

This is generally due to the use of several different chips. Due to the different period of memory bar, a time difference is generated, resulting Dead
, the memory speed can be reduced in the CMOS settings, otherwise, only the same type of memory is used. There is also a possibility that the memory bar is not compatible with the motherboard. Such phenomena are generally rare, and may also be that the memory strip and the motherboard contact with the motherboard caused the computer random crash. 01

Copic fault 5: After the memory is increased, the system resources are reduced

This such phenomena are generally caused by incompatibility between the motherboard and memory. Used on the motherboard that does not support this frequency, when such a failure, you can try to set the memory speed in COMS a little lower.

Copic faults 6: Tips that often appear when running in certain software

This phenomenon is generally caused by insufficient remaining space of the system disk. You can delete some useless files and stay more. Some spaces can be kept at about
300m.

Copic fault seven: from hard disk guidance installation of Windows to detect disk space, the system prompts insufficient memory

This such faults are generally due to the user added to the config.sys file file Emm386.exe files can solve the problem as long as it is shielded.
Themark drive
Themug drive is one of the shortest service life in computer hardware. In fact, many scrapped optical drives still have great utilization value, as long as it is slightly repaired. This often does not need to have any high -level professional knowledge, nor does it need to use too complicated maintenance tools and materials. As long as you carefully observe the fault and refer to some of the following elimination methods, I believe that your old light drive can still return to the "style" in the past.

Copic faults: The hard disk lights are always flashing when the optical drive work

This is an illusion, which is not actually the case. The hard disk light flashing is because the optical drive and the hard disk are connected to an IDE interface, and the result of the hard disk lights also controls the hard disk lights when working. The optical drive unit can be connected to an IDE interface alone.

Copic faults: Display "32 disk access failed" when operating CD-ROM in Windows environment, and then crashes

obviously, 32-bit disk of Windows store It has a certain impact on CD-ROM. Most of the CD-ROM is connected to the IDE interface of the hard disk. It does not support the 32-bit disk access function of
Windows, which makes Windows produce internal errors and crashes. After entering Windows, double -click the "Control Panel" in the "Main Group", enter the "386 Enhancement Mode" settings, click the "Virtual Memory" button, and then click "Change". After verifying the box, after confirmation, restart Windows, and then access CD-ROM in Windows without errors.

Copic fault three: The optical drive cannot read the disk normally. The screen shows: "There is no disk on the drive X, and the disk is inserted before trying", or "CDR101: Not
Ready Reading Drive x Abort .Retry "Fall?" Occasionally, I read and exit the box several times, but I didn't read the disk soon.

In this case, the virus should be detected first, and anti -virus uses anti -virus software to check anti -virus. If no virus can be found to use file editing software to open the config.sys in the root directory of the C drive, " Check whether the light driver and the driver are destroyed and processed, and you can also use text editing software to see if there is "mscdex.exe/d: mscdoo/m: 20/v" in the "AUIOEEXEC.BAT" file If the problem is not found in the above two steps, the optical driver is repaired.

Copic fault four: Reading and writing error or disk prompt during the use of optical drives
n It is caused by the operation of the optical drive when there is no place when the disk is replaced. When the time is adjusted to zero, the disk can be changed, so that the above errors can be avoided.

Copic fault 5: When playing a movie VCD, the picture stops or crushes the phenomenon

Check it up. Whether the "SmartDRV" in the autoexec.bat file is placed behind mscdex.exe. If so, put the SmartDRV statement
before mscdex.exe; /U; failure can be eliminated.

Copic faults 6: When the optical drive reads data, sometimes it cannot be read, and the time of reading becomes longer

The hardware faults produced are mainly concentrated on the laser head component, and can be divided into two cases: one is that the use of laser tube is old
for too long; Dirt and displacement deformation. Therefore, when adjusting the power of the laser tube, it is necessary to clean the photoelectric pipe and laser lens. A set of flat cables of the component, remember the direction, remove the laser head component. At this time, you can see the protective cover covered with a laser head to focus on the lens. On the trace coil, the optical pipe components are installed in the small holes directly below the lens. Wipe with a small amount of distilled water with a fine iron coat (do not wipe the photocarbon and focus on the surface of the lens), and see if the lens is horizontal and the laser is facing the laser. For control, otherwise it must be adjusted appropriately. At this point, the cleaning work is completed.

adjustment of the laser head power. There is a small potentiometer like a cross screw on the side of the laser head component. Using color notes under the initial location Generally, the clockwise rotation is 5 ° ~ 10 ° first, and the installation machine will not rotate 5 ° to 10 ° against the time, until you can read the disk smoothly. Pay attention to cutting too much, so as not to burn the optical pipes too much. R. R. R. R. R. n
Copic fault 7: No light drive or detection failure of the power detection

It can be caused by error caused by the loose data cable connector, the damage of the hard disk data cable, or the error of the optical drive jumping line. Insert it, re -insert it and tighten them. If this still cannot be resolved, then we can find a new data cable and try it. At this time, if the failure still exists, we need to check the jump settings of the CD. If there are errors, change it.
mo
The fault is dirty, disconnected, and mechanical positioning systems. A small number of faults are virtual welding of internal components or circuits, which mainly exist in certain inferior products, especially in the light emitting diodes and IC circuits.

Copic fault 1: I can't find the mouse

1. The mouse is completely damaged, and a new mouse needs to be replaced.
2. The mouse connects serial ports or PS/2 ports of the host. After careful connection, you can restart.
3. The serial port or PS/2 port on the motherboard is rare. If this is the case, you have to replace a motherboard or use the serial port on a multi -functional card.
4. Poor in the mouse line, this is the most common. Poor contacts are mostly connected to the wires and circuit boards inside the mouse. As long as the failure is not PS/2 connectors, it is not difficult to repair. It is usually due to the short line or clutter, which causes the mouse line to be pulled hard. The solution is to open the mouse and use the electric soldering iron to weld the welded joints. Another situation is poor internal contact of the mouse line, which is caused by aging due to a long time. This failure is usually difficult to find. Changing the mouse is the fastest solution.

For the failure of the motherboard BIOS, we can insert the ISA graphics card to see if there is a display (if there is a prompt, you can follow the prompt step to operate.), if there is no turning screen, you can do it yourself yourself一张自动更新BIOS的软盘，重新刷新BIOS，但有的主板BIOS被破坏后，软驱根本就不工作，此时，可尝试用热插拔法加以解决（我曾经尝试过，只要BIOS相同，在The motherboards at the same level can be successfully recorded.). However, the use of the same BIOS with the same BIOS may cause damage to some components of the motherboard. Therefore, the reliable method is to write the BIOS update file into the BIOS with the code writer (it is safe to find a computer dealer with this service).

Copic fault three: The color display is abnormal. Such failures generally have the following reasons:
1. Poor exposure to the graphics card and the monitor signal line
2. The display itself of it r r
3. The color is abnormal when running in certain software, which is generally common in old -fashioned machines. There is an option to check the color in BIOS. 5. The display is magnetized. Such phenomena are generally caused by excessive closeness to objects with magnetic properties. After magnetization, it may also cause a deflection of the display screen.

Copic fault 4: crash

This such faults are generally common in the unsatisfactory of the motherboard and the graphics card or poor contact with the motherboard and the graphics card; Causes crash.

Copic faults: abnormal miscellaneous points or patterns appear in the screen

This is generally caused by the input of the graphics card or poor contact with the motherboard. Need to clean the graphics card gold finger part or replace the display
card.

Copic fault 6: Lost of the graphics card driver

In the graphics card driver is loaded, and the driver is automatically lost after a period of operation. The graphics card and the motherboard are not compatible, making the temperature of the graphics card too high, which causes the system to run unstable or crash. At this time, only the graphics card is replaced.

It, there are a special case. In the past, the graphics card driver could be loaded, but after the graphics card driver was loaded, it fell when entering Windows. After loading its driver in other types of graphics cards, the old graphics card can be replaced. If such faults cannot be resolved, the registry failure can be explained, and the registry can be restored or reinstalled the operating system.
Sound card
Copic failure: Sound card silent. The common causes of this failure are:

1. The driver is output as "mute" by default. Click the sound icon (small cough) in the lower right corner of the screen, and the volume adjustment slider appears. There is a "mute" option below. Click the check box in front to clear the sign in the box to pronounce normally.

2. The sound card conflicts with other plug -in cards. The solution is to adjust the system resources used by the PNP card so that each card does not interfere with each other. Sometimes, "Equipment Management" is opened. Although the yellow exclamation mark (conflict sign) has not been seen, the sound card is not sounding, but there is actually a conflict, but the system has not been checked.

3. The sound card after installing x is installed. It shows that the compatibility of this sound card and Direct X is not good, and the driver needs to be updated.

4. A channel is silent. Check whether the audio cable from the sound card to the speaker is disconnected.

Copic fault two: The noise emitted by the sound card is too loud. The common causes of this kind of failure are:

1. Inserture cards. Due to the insufficient accuracy of the chassis and the poor sound card baffle manufacturing or installation, the sound card cannot be closely integrated with the motherboard extension slot. The visible "golden finger" on the sound card is misplaced with the expansion slot reed. This phenomenon is on the ISA or PCI card, which is a common failure. Generally can be used to correct with pliers.

2. The Speaker output terminal connected to the sound card. For active speakers, it should be connected to the LINE OUT end of the sound card. The signal it outputs
has not passed the amplifier on the sound card, and the noise is much smaller. Some sound cards have only one output end, whether LINE OUT or Speaker depends on the jump on the card. The manufacturer's default method is often Speaker, so you need to unplug the sound card to adjust the jumper.

3. The driver comes with Windows is not good. When installing the sound card driver, select "Driver provided by the manufacturer" instead of
"Windows default driver" if you install it in a "adding new hardware", you should choose "installation from the disk" instead of Select from the list box. If the driver comes with Windows has been installed, the "control panel → system → device management → sound, video and game controller" can be selected, each sub -device, select the "attribute → driver → change the driver → from the disk Install". At this time, the disk or disc paired with the sound card is inserted into the driver provided by the manufacturer.

Copic fault three: sound card cannot "plug and play"

1. Try to use the new driver or replacement program as much as possible. I used to have a sound card. Under Windows 98, I could n’t install the driver with the original driver disk. I had to use the Creative SB16 driver instead, everything was normal. Later, it was upgraded to Windows ME, and it was not normal to change the sound card driver with Windows 2000 (full version).

2. The most headache is the detection of plug -and -play device under Windows 9X, but it is self -made to help you install the driver. This driver cannot be used. If you delete the reinstallation, you will repeat this problem, and you cannot solve the method of "adding new hardware". The author leakes a unique trick here: enter the directory, delete all the * .inf files about the sound card and then start it manually. This is a 100 % spiritual inspection. It can also achieve the same purpose.

3. Installation of PNP sound cards (also applicable to PNP sound cards that cannot be installed in the above PNP method): Enter "control panel"/"add new hardware"/"next step", as prompts as prompts "Do you need Windows to search for new hardware?", Select "No", and then select "Sound, Video and Game Controller" from the list to install it with a drive disk or directly select the sound card type.

Copic fault four: Play CD silently

1. Put the CD silently with the "CD player" of Windows 98, but the "CD player" is working normally, which shows that the audio cable of the optical drive is not connected. Use a 4 -core audio cable to connect CD -ROM analog audio output and CD -I in the sound card. This cable will be attached when purchasing CD -ROM.

2. There is only one channel sound. The output port of the optical drive generally has two signals on the left and right lines, and the middle two lines are ground lines. Because the 4 lines of the audio signal line are generally different, the corresponding interface can be found from the color of the line. If there is only one interface on the sound card or each interface does not match the audio cable, you have to change the wiring order of the audio cable, usually only the two lines can be replaced.

Copic fault 5: PCI sound cards appear explosive

generally because the PCI graphics card uses Bus Master technology, it is enlarged by the hard disk reading and writing, mouse movement and other operations hanging on the PCI bus. Background
This noise. Solution: Turn off the Bus Master function of the PCI graphics card, replace it with an AGP graphics card, and change the PCI sound card to the slot.

Copic failure 6: Can't recording normally

Ploped to check if the microphone was inserted into other jacks. → Recording "to see if the settings are correct. Next, the "mixed device" and "line input equipment" are adjusted in "Control Panel → Multimedia → Equipment" and set them to "use". If the "recording" option in "Multimedia → Audio" is gray, it is bad. Of course, it is not no room for saving. You can try the "ISA Plug and Play Bus" in "Add New Hardware → System Equipment". , Simply start the sound card with the card tool software.

Copic fault seven: cannot play WAV music, MIDI Music

This WAV music phenomenon is rare, often due to "multimedia" → "audio equipment" under "equipment" "Not only one, just disable one; the MIDI file cannot be played:

1. Early ISA sound card may be due to the 16 -bit mode and 32 -bit mode. Not normal, the
method of installing the software wave table should be able to solve

2. Most of the popular PCI sound cards today use wave table synthesis technology. You do not load the appropriate wave sound library.

3. The MIDI channel in Windows volume control is set to be mute mode.

Copic fault eight: PCI sound card uses abnormally under Win98

It users report that everything is normal during the installation of the sound card driver, and there is no equipment conflict, but in the past Win98 below is unable to make a sound or other faults occur. This phenomenon usually appears on the PCI sound card. Please check which PCI slot you inserted PCI sound card during the installation process. Some friends like to insert their sound cards away from the AGP slot and near the ISA slot near the ISA slot. The problem often appears here, because the Windows98 has a bug: sometimes it can only correctly identify the sound card that is inserted in PCI-1 and PCI-2. The two PCIs that are close to AGP on the ATX motherboard are PCI-1 and PCI-2 (just on the opposite of some ATX motherboards, PCI-1 is close to ISA), so if you do not install the PCI sound card on the right correct On the slot, the problem will occur.
memory

M memory is one of the most important accessories in the computer. Woolen cloth?

Copic failure: No display

The cause of memory bar. Such failure is caused by poor contact with the motherboard memory slot. Try its golden finger parts to solve the problem (do not use alcohol and other cleaning), and there is a problem with memory damage or motherboard memory slot, which will cause such faults.
The no display failure caused by the instrument of the memory, the host speakers generally have a long time of bee (for Award Bios).

MST: Windows registry is often damaged for no reason. It is prompted that users are required to restore

This is generally caused by poor memory quality and it is difficult to repair it. Only replace it.

Copic fault three: Windows often automatically enter the security mode

This is generally caused by the inadequate compatibility of the motherboard and memory or memory bar, which is common in high frequency The memory is used on the motherboard that does not support this frequency memory bar. You can try to reduce the memory reading speed in the CMOS settings to see if it can solve the problem. If not, you can only replace the memory bar.

Copic fault 4: Random crawling

This is generally due to the use of several different chips. Due to the different period of memory bar, a time difference is generated, resulting Dead
, the memory speed can be reduced in the CMOS settings, otherwise, only the same type of memory is used. There is also a possibility that the memory bar is not compatible with the motherboard. Such phenomena are generally rare, and may also be that the memory strip and the motherboard contact with the motherboard caused the computer random crash. 01

Copic fault 5: After the memory is increased, the system resources are reduced

This such phenomena are generally caused by incompatibility between the motherboard and memory. Used on the motherboard that does not support this frequency, when such a failure, you can try to set the memory speed in COMS a little lower.

Copic faults 6: Tips that often appear when running in certain software

This phenomenon is generally caused by insufficient remaining space of the system disk. You can delete some useless files and stay more. Some spaces can be kept at about
300m.

Copic fault seven: from hard disk guidance installation of Windows to detect disk space, the system prompts insufficient memory

This such faults are generally due to the user added to the config.sys file file Emm386.exe files can solve the problem as long as it is shielded.
Themark drive
Themug drive is one of the shortest service life in computer hardware. In fact, many scrapped optical drives still have great utilization value, as long as it is slightly repaired. This often does not need to have any high -level professional knowledge, nor does it need to use too complicated maintenance tools and materials. As long as you carefully observe the fault and refer to some of the following elimination methods, I believe that your old light drive can still return to the "style" in the past.

Copic faults: The hard disk lights are always flashing when the optical drive work

This is an illusion, which is not actually the case. The hard disk light flashing is because the optical drive and the hard disk are connected to an IDE interface, and the result of the hard disk lights also controls the hard disk lights when working. The optical drive unit can be connected to an IDE interface alone.

Copic faults: Display "32 disk access failed" when operating CD-ROM in Windows environment, and then crashes

obviously, 32-bit disk of Windows store It has a certain impact on CD-ROM. Most of the CD-ROM is connected to the IDE interface of the hard disk. It does not support the 32-bit disk access function of
Windows, which makes Windows produce internal errors and crashes. After entering Windows, double -click the "Control Panel" in the "Main Group", enter the "386 Enhancement Mode" settings, click the "Virtual Memory" button, and then click "Change". After verifying the box, after confirmation, restart Windows, and then access CD-ROM in Windows without errors.

Copic fault three: The optical drive cannot read the disk normally. The screen shows: "There is no disk on the drive X, and the disk is inserted before trying", or "CDR101: Not
Ready Reading Drive x Abort .Retry "Fall?" Occasionally, I read and exit the box several times, but I didn't read the disk soon.

In this case, the virus should be detected first, and anti -virus uses anti -virus software to check anti -virus. If no virus can be found to use file editing software to open the config.sys in the root directory of the C drive, " Check whether the light driver and the driver are destroyed and processed, and you can also use text editing software to see if there is "mscdex.exe/d: mscdoo/m: 20/v" in the "AUIOEEXEC.BAT" file If the problem is not found in the above two steps, the optical driver is repaired.

Copic fault four: Reading and writing error or disk prompt during the use of optical drives
n It is caused by the operation of the optical drive when there is no place when the disk is replaced. When the time is adjusted to zero, the disk can be changed, so that the above errors can be avoided.

Copic fault 5: When playing a movie VCD, the picture stops or crushes the phenomenon

Check it up. Whether the "SmartDRV" in the autoexec.bat file is placed behind mscdex.exe. If so, put the SmartDRV statement
before mscdex.exe; /U; failure can be eliminated.

Copic faults 6: When the optical drive reads data, sometimes it cannot be read, and the time of reading becomes longer

The hardware faults produced are mainly concentrated on the laser head component, and can be divided into two cases: one is that the use of laser tube is old
for too long; Dirt and displacement deformation. Therefore, when adjusting the power of the laser tube, it is necessary to clean the photoelectric pipe and laser lens. A set of flat cables of the component, remember the direction, remove the laser head component. At this time, you can see the protective cover covered with a laser head to focus on the lens. On the trace coil, the optical pipe components are installed in the small holes directly below the lens. Wipe with a small amount of distilled water with a fine iron coat (do not wipe the photocarbon and focus on the surface of the lens), and see if the lens is horizontal and the laser is facing the laser. For control, otherwise it must be adjusted appropriately. At this point, the cleaning work is completed.

adjustment of the laser head power. There is a small potentiometer like a cross screw on the side of the laser head component. Using color notes under the initial location Generally, the clockwise rotation is 5 ° ~ 10 ° first, and the installation machine will not rotate 5 ° to 10 ° against the time, until you can read the disk smoothly. Pay attention to cutting too much, so as not to burn the optical pipes too much. R. R. R. R. R. n
Copic fault 7: No light drive or detection failure of the power detection

It can be caused by error caused by the loose data cable connector, the damage of the hard disk data cable, or the error of the optical drive jumping line. Insert it, re -insert it and tighten them. If this still cannot be resolved, then we can find a new data cable and try it. At this time, if the failure still exists, we need to check the jump settings of the CD. If there are errors, change it.
mo
The fault is dirty, disconnected, and mechanical positioning systems. A small number of faults are virtual welding of internal components or circuits, which mainly exist in certain inferior products, especially in the light emitting diodes and IC circuits.

Copic fault 1: I can't find the mouse

1. The mouse is completely damaged, and a new mouse needs to be replaced.
2. The mouse connects serial ports or PS/2 ports of the host. After careful connection, you can restart.
3. The serial port or PS/2 port on the motherboard is rare. If this is the case, you have to replace a motherboard or use the serial port on a multi -functional card.
4. Poor in the mouse line, this is the most common. Poor contacts are mostly connected to the wires and circuit boards inside the mouse. As long as the failure is not PS/2 connectors, it is not difficult to repair. It is usually due to the short line or clutter, which causes the mouse line to be pulled hard. The solution is to open the mouse and use the electric soldering iron to weld the welded joints. Another situation is poor internal contact of the mouse line, which is caused by aging due to a long time. This failure is usually difficult to find. Changing the mouse is the fastest solution.
