Common Drive Fault resolution method

　　Driver is a basis for us to use the operating system, without it, we can not hear the sound, can not see the picture, on the net. Let's take a look at common drive failure solutions, detailed explanation, simple operation.

　　First, the basic knowledge: how to implement the Device Manager problem symbol.

　　1, the Red Fork number

The hardware devices in the "IEEE 1394 bus Master" and "PCMCIA Cards" show a red fork in the previous Diagram window, which means that the device has been deactivated, in fact because the author's laptop does not often use 1394 devices and PCMCIA cards. These devices are disabled from the considerations of saving system resources and increasing startup speed.

Workaround: Right-click on the device and select "Enable" from the shortcut menu.

　　2, yellow question mark or exclamation number

If you see a yellow question mark or exclamation point before a device, the former indicates that the hardware was not recognized by the operating system, which means that the hardware does not have a driver installed or the driver is not installed correctly.

　　Solution: First, we can right-click on the hardware device, select the "Uninstall" command, and then reboot the system, if it is the Windows XP operating system, most of the time will automatically identify the hardware and automatically install the driver. However, in some cases you may need to insert a driver disk, follow the prompts.

　　Second, sound card

　　1, Windows hint did not find a hardware driver

This type of failure is typically due to not completing the first time the driver was loaded, or in Config.sys, automatic batch file Autoexec.bat, A sound card driver is already running in the Dosstart.bat file, so you can delete one of the driver files that are running inside, or remove the three files mentioned above to resolve the failure. If there are no files in the top three files, and the driver can not install, at this time need to modify the registry, click the "Start" menu-"Run", enter the dialog box "regedit" return, the sound card associated with the registry keys deleted (such as the sound card model ALS300, click the registry key to edit "--Find, enter ALS300, then delete the found bytes, and press F3 to continue to find the next, and then delete the options found."

　　2, sound card driver obsolescence caused system failure

　　Symptom: An old machine recently installed Windows XP system, the installation process is very smooth. Windows XP system is a large memory-consuming, plus a second-hand 128MB SDRAM memory to make the system run more smoothly. But soon the problem came: during the operation of the system frequently crashes, especially in the Internet and QQ chat when the fault occurs most frequently.

　　Analysis Solution: because the system installation is very smooth, is not installed second-hand memory caused by the fault? So first remove that memory, reboot after the failure is still. Is it that the motherboard driver is too old to be compatible with the new Windows XP system? Try to find the motherboard for a new driver update, did not find, but accidentally found the onboard AC ' 97 sound card of the new driver, although the sound card has been working properly, but also by the way to download to try first. Remove old sound card driver, install new drive reboot, troubleshoot. It turns out that the sound card driver is stale, causing system failures that are not good enough for compatibility with Windows XP.

　　3, the driver loading completed after the sound card silent

First of all, look at the sound card and speaker wiring is correct, speaker signal line should be connected to the sound card of the speaker or SPK port, if the wiring is correct and then enter the Control Panel multimedia options, see if there is no sound equipment, a device to explain the sound card driver normal loading, otherwise the driver did not successfully install or there is a device conflict, If there is a device conflict can be resolved by dismount:

1 The sound card to replace the slot (on the author's experience, the sound card, modem and other expansion cards into two or three, four or five slots better, because a slot will generally be with the graphics card conflict). Enter the sound card resource setup option to see if its resources can be changed to a conflict-free address or interrupt.

2 Enter the reserve resource project to see if the sound card use resources can be retained and not used by other devices. See if there are any jumpers on the sound card to change the interrupt port.

3 Shut down unnecessary interruption resource usage, such as ACPI function, USB port, infrared device, etc. Upgrade the sound card driver.

4) Load the motherboard driver and try again. In the multimedia options mentioned above, if there is a sound device, but sound card, can enter the sound card volume adjustment menu to see if it is set to mute, there is a more special situation, some sound card must be installed in the driver's setup, so that first in Coufig and AutoExec, bat files, Create some files that drive your sound card to occur normally under Windows (for example, a 4DWAVE sound card).

　　4, AC ' 97 sound card driver failure and treatment

　　Failure Analysis: in the desktop task bar in the voice of the "Small horn", click can also be normal volume control, only speakers can not be audible (due to the previous speaker has been normal, so you can eliminate the speaker out of the possibility of failure). Speakers are not sound because of the audio driver installation errors caused.

　　Troubleshooting: The author deletes the "Soundmax integrated Digital Audio" item in "Device Manager", restarts the machine, puts the drive disc that comes with the motherboard into the optical drive, the CD automatically runs, and displays in the second item "VIA AC97 PCI Sound Drivers ", click into the sound card driver installation interface, and then the system prompts: onboard sound card has been disabled, please reset in the BIOS. into the BIOS, to find "Integrated peripheral setup" in the "onboard AC97 Audio", set to "Enabled", it appears that Win98 in the false military intelligence. Enter the system again, open the properties item in Device Manager for Soundmax integrated Digital Adio, select Upgrade driver in driver, and in the Upgrade Device Driver Wizard, select Show list of all drivers for the specified location. So that you can select the driver you want from the list, click Next, select Install from floppy, browse driver location: soundviamvp4win98se, finally found "VIA AV97 Audio CONTROLLERWDM", click "Next", System Warning: The selected driver is not designed for selected hardware and may not function correctly ... Select "Yes", after the installation is completed restart the machine, the familiar Win98 start sound finally passed out from the speaker. into Device Manager, in "Voice, video and game controllers", there is the "via AC97 Audio CONTROLLERWDM" entry, which is the true via AC ' 97 sound device. Using the same method, all machines are successfully fitted with the correct driver and the fault is removed.

　　5, Windows XP and innovative sound card driver conflict

This situation may be caused by problems with the driver itself that Windows XP brings. Because innovation does not release the driver for this sound card under Windows XP, because Windows XP is developed by Windows 2000, you can replace the sound card with a driver on Windows 2000, which can always be resolved.

　　6, Wrong installed sound card driver caused by the fault

Failure phenomenon: After reloading the WinXP system, the first time to turn on the TV card program to watch TV, the sound card can be normal pronunciation, but after switching to other channels, TV shows no sound. After exiting, it is not possible to reopen the TV playback program. You can only restart your computer and watch a TV show when you have sound, but continue to repeat the failure once you have converted the program channel. And this fault only in the use of TV card when appearing, in the failure occurred before and after, play other multimedia files, sound card can be normal pronunciation.

Troubleshooting process: Because the TV card is through an audio line, connect to the sound card of the line input, you can watch the TV show when there is a sound, so I first put this audio cable unplugged, directly to the audio box to the TV card output, the sound is normal, that is, the elimination of the TV card has a problem with the sound, After replacing the connector, the problem still persists. Later in the BIOS setup, I disable the sound card before I can uninstall the original sound card driver. After uninstalling the sound card driver, I put the sound card in the BIOS setup back on, after entering the computer, let the WinXP automatically look for the driver of the sound card on the motherboard driver, the system will find the driver location quickly, and automatically install the sound card driver, but the fault still exists.

In order to determine the sound card model, I opened the chassis, found that the motherboard's sound card chip is indeed CMI9739. Then I uninstall the original sound card driver, and then reinstall the driver of the CMI9739 sound card to troubleshoot.

　　Third, graphics card

　　1, the problem of graphics driver failure

After reinstalling the operating system, it is found to be a yellow question mark before the video controller (VGA-compatible) in "Other Devices" in "Hardware Device Manager". Classmate said this phenomenon is because the graphics card does not install the driver caused by, but my motherboard and graphics card is integrated, do not know the integrated graphics model.

I used the Everest software to test the graphics card model but I can't detect it. It was later found that the motherboard specification, which was written using the Via K8M400 chipset, where can I download the graphics driver for the chipset?

Workaround: This is a classic problem, some hardware is too old to be able to identify the motherboard, but know the motherboard chipset model, then the driver is not a problem.

　　2, no display on the boot

This type of failure is typically due to faulty graphics card contact with the motherboard or problems with the motherboard slots. For some integrated graphics boards, if the video memory sharing main memory, you need to pay attention to the location of the memory bar, generally in the first memory slot should be inserted in the memory bar.

The above is the common drive failure solution, detailed explanation, simple operation. Hope can help you solve the computer problem!
