well i just built a new machine. i have a gigabyte m51gm-s2g motherbaord, with a socket am2 athlon 64 3800+, 1 gig of corsar ddr2 800 ram and a wd sata2 hd.
well when i first built the machine i used a gig of crucials ballistick x ddr2 800 and the system kept on crashing and i was getting a blue screen of death. "windows is displaying this to prevent damage to your computer... dumping physical memory" and i figured out that one of the ballistix modules was bad. so i replaced it with the corsair and it ran fine for about 8 hours no probelm then it crashed with another blue screen i ran memtest 86 and this time i came up with no errors so i have no idea what the problem is. i think its the motherboard but how do i test it??? or if anyone else has an idea?
