I had to format my computer a few times because of a virus, and then i had to take out half my RAM cause it wasnt working correctly. I though my comp was finally back to normal, but then my sound stopped working. I have an eMachine T6520 PC, Windows XP: Media Center Edition, and my sound card is a Realtek AC97(its integrated, its not a seperate card). I downloaded the driver for the sound card from the Realtek site, and it seemed to install, but the sound still didnt work, and "Multimedia Audio Controller" shows up in my device manager under Other Devices with a big, yellow question mark before it. It says "This device is not configured correctly. (code 1)" The lovely little beeping noise my computer makes instead of the sound is REALLY starting to get on my nerves, so id really appreciate any help.
