Sorry if this post is a repeat but I just spent 3 hours looking for anything close to it and 2 days of looking on the web. If you know of such a post please tell me. I just formated my hard drive, I downloaded the 66.93 NVidia drivers (cause those are the only ones that work), and now my games are smooth but the screen randomly locks up. I have no idea what else i need, and am in need of help. My PC worked almost perfect before the format. 3200+ (2GHz) AMD Antholon 64 1024 Gig RAM NVidia 6800 GT 256RAM Thank you P.S. If you need more info I'll do my best to get it.
