I'm installing windows xp and i get an error message "IRQL_NOT_LESS_OR_EQUAL". I've heard people say its because of out of date drivers. That can't be possible in my case because this is my first time turning on this new pc. Amd 4000+ Nvidia geforce 6800 GT SATA 10kRPM 74gb SATA 7200RPM 320gb Im trying to put the OS on the 10krpm drive. But i'm getting the blue screen error message.
