Ok here is my recomendation for what it is worth. Format the system, Reinstall windows, install and update your sound card drivers 1st, then intall your mobo drivers and such, then run windows update, then update your video drivers, then update DX9. then install all of your games, then update all your games to the latest version. do all of that in the order that i wrote and i would bet5 asses to apples your problem will dissaper.
