System: Asus a8n sli deluxe nvidia 6800gt 2 corsair xms 512mb ram 200gb western digital caviar SE 7200rpm logitech mx1000 and keyboard dell ultrasharp monitor Ok. this is really weird. I built a new computer and for the first 2 months it was working fine. Then, i got hit with a few random restarts about device driver error. Strange because i hadn't installed any new drivers. Then this error turned into system hardware error. I had my friend fix my bios timings and then the restarts reverted back to device driver errors. I checked windows update and all drivers seem ok. scanned for malware, viruses, and spyware and all clear. Also ran memtest86 five times and it seemed fine. However, i just ran prime95 and it detected a hardware error. ARGH. i have no idea what is wrong and it is killing me. by the way, they are completely random restarts. not when i open an application or something. Thanks for the help guys.
