Did a little search for this as I was having a problem similiar to yours on my old computer (I've since gotten a new one and don't remember how I fixed the old problem) It appears that it could be the mic, or a ground loop issue. Do a google search for "random loud static from sound card while playing" and see if any of those solutions help.
