ok, I installed my new mb, a msi 790FX, and a phenom, and when I go to start up windows, it just goes to the windows xp boot screen then restarts automatically. I'm not sure if I need to update bios for it to supprt the phenom and put back my dual core, or what but when I try to re-install windows it loads the disk and files, and after t says windows is starting up or w/e it gives me a blue screen. plz help asap, im at school and have no other computer at home. edit: there is no beeps or anything.
