So I disabled HD audio, and that solved the problem... for about a week. Then the problem came back. So I reinstalled the
drivers, which also worked... for about another week. So then I stopped using itunes. Problems seems to be solved. Might try upgrading itunes, which I don't like doing, and don't see why itunes would suddenly start doing this, since I haven't upgraded it in a while. Also, the problem didn't only happen when running itunes, but also when gaming (this has also stopped). Thoughts? Thanks a lot for helping me through this even as far as we've gotten! Even if I'm using aweful WMP for now, I've at least stopped the BSODs :-D
