Help! im missing a driver after i downgraded to XP

I had Vista in my computer but recently downgraded to XP and now im missing a driver from my PC. its the PCI Device which im sure is what is causing my "No Sound" issue. can anybody please help me?

 

That happens, check with your computers manufactor to see if they offer xp drivers.

 

You need to figure out what kind of sound card you have before we can help you find a driver for it. they are easy to find though try http://www.driverguide.com/

If you don't know your card specs try using http://www.majorgeeks.com/EVEREST_Free_Edition_d4181.html
to figure it out

 

Device Description Type
Intel 82801GB ICH7 - High Definition Audio Controller [A-1] PCI


is that it? I'm kinda new at this and if anybody has AIM please send me a message at Kamikaze Soul X to make things go quicker....this having no sound issue is irritating
