Why doesnt Windows XP recognize my audio driver after loading iTunes 7? -

I m running Windows XP SP2 and my iTunes and Windows Media player used to work fine. But when I recently installed iTunes 7.7.0.43 and Quicktime 7.5, my system is not recognizing the audio driver anymore and I can t play anything no matter what software I use. Help!

Try using system restore; I think its Startgt;Help amp; Support.
