WinXP not recognizing sound card installed

November 9, 2010 at 11:23:50
Specs: Windows XP, P4-2.2GHz/2GB
I have a Compaq Evo D510 with WinXP SP3 installed. I had disabled the onboard audio, and installed a C-Media 8768 8-ch PCI audio card. It was working up until about 2 weeks ago. I then bought a new computer, so I removed some components from the P4 to move to the new computer. I removed the audio card, though I didn't put it in the new computer. Unfortunately the new computer had mobo issues, so I sent it for repairs. I put the other components back in the P4, except the audio card. I then enabled the onboard audio, and installed the drivers from HP's website. Windows recognized the drivers and the card, but Sound and Audio Properties reported no audio card available! I then tried uninstalling the onboard audio card drivers, reinstalled the PCI audio card, and reinstalled the drivers for it. Again, Windows recognizes the PCI audio card drivers (it even shows up under Device Manager), but Sound and Audio Properties still says there is no audio card present. Any ideas on what's going on, and how I can fix it short of a Windows reinstall?

Thanks.
David

God bless

The term "CARD" is frequently mis-used. A sound or video or network adapter , etc. that's built into the mboard IS NOT A CARD ! An adapter is also a CARD ONLY if it is on a physical card or module that plugs into a slot or connector inside the computer case on the mboard, and can be removed !

Sound and video "drivers" always have associated files that must be installed properly along with the actual drivers. If you install only the actual drivers, it's likely the device will NOT work properly.

Unless the instructions for installing a device tell you otherwise....
(this ALWAYS applies to video and sound adapters )

You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !

If you DID install drivers that way,

(The following also applies if you want to un-install previous software, or re-install the same software)

- for video "drivers"....

- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, let the desktop screen fully load.

Install the video software properly by running the proper download you got from the web, or if you have the CD that came with the video card that's in a slot, or if you have the CD that came with the brand name computer that has the Drivers on it, run the video software installation from the installation program on that.

for sound adapter "drivers"...

- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting.

- go to Device Manager.
(e.g. RIGHT click on My Computer - Properties - Hardware - Device Manager)
If the sound adapter is still listed, RIGHT click on it and Un-install it.
If that was there, and you un-installed it, Reboot at least once.
DO NOT install drivers while booting.

Install the sound software properly by running the proper download you got from the web, or if you have the CD that came with the sound card, or if you have the CD that came with the brand name computer that has the Drivers on it, run the sound software installation from the installation program on that.
........

Windows supports you installing more than one sound adapter, but it can use only one of them at a time.
The sound adapter you installed the "drivers" for last becomes the adapter Windows uses by default.
You can change which sound adapter Windows uses in Control Panel - Sounds and Audio Devices - Audio.
