First off... I have to say it's a little annoying that you've seemed to spread this issue out between three different posts. I had to dig to find your hardware specs.
Second... I doubt the audio card is the issue. Looking back over the history of your posts, you mentioned that you "ruined one hard drive" over DAO... which frankly find hard to believe.
I suspect the proper solution to your problem is what I call the "nuclear option"-- a complete re-installation of Windows XP SP3. If you want to add a new audio card, lovely, it can't hurt... at the same time you have the case open, I'd suggest giving your PC's innards a good dusting, and make sure all cards/memory modules are seated properly.
But I think a lot of what you're dealing with is a stale installation of Windows.
EDIT: I don't suggest this lightly, however. But suspicious of any system where you've reported (in different posts) video, audio, and performance problems. Anyway, if you have the discs and take a few days to back up whatever data you need, reinstalling Windows is an invenstment of time, but not much money.
