Let me tell you my problem in detail so maybe something can be determined out of it..

Ok my sound card messes up for some reason, every once in a while it makes really loud scratchy noises preventing me from hearing anything else other than that. sometimes the sounds come straight out and really loud or they start low and build up to a loud scratchy sound, even when the computer isnt being used (but of course is on)

this problem has been on for a while, with both windows 2000 and XP. im thinking i need to update the driver.. but im not sure. I think it could be more than that.

so.. any ideas?
