Unknown Audio Controller and Video card..

[e2thejdot]

Here's the deal.. I had some unknown virus that was causing my computer to run horribly, so I reformatted it today. Can't find the discs for the drivers. I found out (after downloading some analysis programs and searching around on the net) that I have a nVidia C51 chipset, if that helps. Both my audio and video is onboard (came with the motherboard). I downloaded the drivers for that chipset off the nVidia site.. it did nothing for my audio or video. I tried Everest.. its telling me nothing that makes much sense. Under PCI/PnP Audio it has the same thing listed Device Manager for XP does.. Multimedia Audio Controller. Anybody got any ideas?
