i have a generic 56x cdrom drive that worked fine untill about a week ago. everytime i try to play a cd or any game i get the blue screen of death that says "machine check exception" or something. ive tried reinstalling the drivers and everything but nothing works. could it be the cdrom just doesnt work anymore or what. i am running xp and ive ran antivirus and spybot, thinking it that might have something to do with it, but my system is clean. any thoughts?
