1, Windows prompts the driver did not find the hardwareSuch failures are generally due in the first loaded driver is not properly completed, or in the , automatic batch file , document has been running for a sound card driver, which can be a driver running inside the deleted files can, of course, you can also delete the three files mentioned above to solve the problems. If not in the above three files inside any file, and then install the driver does not go, then need to modify the registry, click the “Start” menu – “Run” in the dialog box, enter “regedit” enter, will be delete registry entries related to the sound card (sound model for the ALS300, click the registry key “Edit” – “Find”, enter the ALS300, and then find the deleted bytes, and then F3 to find next, followed by will find the option to delete it.)There is also a most convenient way is the sound card into another slot, re-found a new device, load the driver fix the problem. Although the second method seems simple, but we troubleshoot hardware or software to follow the principle of the first is appropriate, just before making the first method guide the user the best out of the registry backup it first in case of emergency.
2, the old sound card driver cause system failureFailure phenomenon: an old machine recently installed Windows XP system, the installation process is very smooth. The Windows XP system is the large memory consumption, but also installed a second hand 128MB SDRAM memory to make the system run more smoothly more. But soon the question becomes: in the frequent crashes the system during operation, especially in the QQ chat online and the most frequent failure.Analyze and solve: because the system installation is very smooth, is not caused by the installation of second-hand memory fault it? So first remove the piece of memory, re-boot failure remains. Application software and systems in order to exclude conflict, so reinstall the system, but the failure remains. Taking into account the aging and the power adapter failure can also result in similar phenomena were to be replaced after the fault is not excluded. Now the weather is very hot, is not it crashes caused by bad CPU cooling phenomenon it, detect in the BIOS CPU temperature did not exceed 46 ???????, ruled out the suspicion of CPU cooling efficiency. Finally, the problem seems to be concentrated in the motherboard and hard drive on the. Seagate hard drive upgrade is the new 20GB, there should be no problem, the system tests also proved this point. Could that be the motherboard drivers too old and the new system is not compatible with Windows XP? The Internet trying to find a new motherboard driver updates, did not find, but accidentally discovered a new driver onboard AC’97 sound card, although the sound card has been working properly, but also the way to first try to download. Remove the old sound card drivers, install the new drive to restart after troubleshooting. Turned out to be old sound card driver, and Windows XP compatibility result is not good enough due to system failure.
3, after the driver into the silent soundFirst of all, to see the sound card and speaker wiring is correct, the speaker of the signal line should be connected to the sound card speaker or spk port, if the wiring is correct and then go to Control Panel, multimedia options, look inside without the sound equipment, a device that the normal sound card drivers loaded, or driver is not successfully installed or existing equipment conflicts, should there be press law device to resolve the conflict:
1) to change my sound card slot (in my experience, the sound card, MODEM and other expansion card into two, three, four, five slots better, because a tank will generally cause a conflict with the graphics.)
2) resources into the sound card to see its resources can set options to change the address with no conflict or disruption.
3) into the reserved resources to the project, to see whether the sound card to retain the use of resources to prevent other devices.
4) to see whether the jumpers on the card can change the interrupt port.
5) Turn off unnecessary interruption resource consumption, such as ACPI function, USB port, infrared and other equipment.
6) Upgrade sound card driver.
7) into the motherboard drivers and try again. In the above mentioned option in any multi-media audio device, but the silent sound card, sound card volume control to enter the menu if there is a muted, there is a special case, and some sound card drivers must be used within SETUP to install, making it first in the COUFIG and AUTOEXEC, BAT files, create some of the sound card driver files to function properly in place under WINDOWS (eg 4DWAVE sound card).
4, Windows XP sound card drivers and innovative conflictThis may be caused by Windows XP driver caused the problem itself. Because innovation is not the publication of the sound card in the driver under Windows XP, but Windows 2000 Windows XP is evolved, we can use the sound card drivers on Windows 2000 instead, so that can always be solved.
5, the wrong sound card driver installation failure caused bySymptom: After reloading WinXP system, the first turn on the TV card to watch TV programs when the program, sound can be pronounced correctly, but switch to other channels, the TV show there is no sound. After withdrawal, re-open the TV player does not work. Can only restart the computer, watching television programs when it can have sound, but as long as a conversion program channels, which continues to repeat the failure. Moreover, this failure only when you use the TV card, after the fault occurs, play other media files, sound cards, can be normal pronunciation.Troubleshooting process: the TV card audio through a line connected to the sound card’s line input, it can sound when watching TV, so I first pulled this audio cable directly to the speakers to TV card audio output port, the results sound normal, which is excluded from the TV card’s sound output problems, but after replacing the cable, the problem still remains.
Therefore, I determine a computer’s sound card out of the question. As silent watching TV after a fault occurs, the computer plays other multimedia files, sound cards can be a normal voice, so I suspect the sound card drivers and TV card driver conflict, but in my sound card drivers to the uninstall process, the computer automatically restarts unexpectedly and can not use safe mode into the system. Later in my BIOS settings, disable the sound card only after the original sound card drivers to uninstall. Uninstall sound drivers, I put the sound card in BIOS settings to re-open, into the computer, so that WinXP automatically find the motherboard drivers sound card drivers on the disk, the system quickly find out the location of the driver and automatically install the sound card driver , but the fault still exists.Reinstall the TV card driver then can not solve the problem, reinstall the operating system before because the computer can be a normal television programs.
Is not a TV card and motherboard integrated sound card is not compatible with it? With this question, I checked the TV card and the motherboard manual, but instructions are stated on the WinXP system compatible. The motherboard manual is written in the sound card model, but it caught my attention because the motherboard manual to write the sound card model is CMI9739, and have the system automatically when the sound card driver installed, install the sound card is ALC100 driver. In order to determine the model of sound card, I open the case and found that the chip is indeed the motherboard sound card CMI9739.
After I uninstall the original sound card drivers, then reinstall the CMI9739 sound card drivers, troubleshooting.In general, the sound card driver installation errors, the computer can not properly pronounce, but then I tried it on other computers and found that ALC series audio driver installed, the integrated motherboard VTI612A and CMI9739 chips can be pronounced correctly , but there will be compatible with the TV card is not the problem. WinXP operating system and often in the process of installing the driver, we all used to just click Next, at the expense of the system automatically find the drivers to choose from. It is recommended that you install the sound card driver, the best look at the motherboard manual or look on the motherboard sound chip model.
