I just recently added a new EVGA nforce4 SLI motherboard, Athlon 64 3200+, and a EVGA 7800gtx. Now when I try to boot up, it says windows did not start up successfully. It has safe mode, safe mode with networking, safe mode with command prompt, last known good configuration, and normal booting. I tried them all, but suddenly I get a flash of a BSOD and the computer reboots. Even if i leave it alone at the booting menu, it repeatdley reboots by itself. I don't know what to do. I tried different RAM also.
