sound card drivers.
The PCI device is your sound card. You will need to find the drivers on line or on the sound card CD you've misplaced.
The other two could be anything. Get the PC running with sound and holler back.
I just used dban (http://dban.sourceforge.net) to wipe my hard drive of Vista, and have finally got XP working.
However, my sound card is not detected anymore. I know 100% it was working with Vista, but since the reinstall, all I get is a system beep and no sound card is listed anywhere in my system information > components.
In device manager, I have 3 question marks next to:
USB 2.0 Camera
I wonder if any of these is the problem? I don't know what to do about them though, as I cannot get windows to successfully install the drivers from the disk, or find them anywhere else.
