that's the build running XP 32 bit

the problem in anything but low rez settings on games like COD4 , EQ2, it locks up with graphic glitches,

in Crysis even in low rez , lock up , freeze, graphic glitches,

since the raidmax PSU is crap i recomended changing that first, now its changed still having same problems though

any advice for him ? and no he has not contacted evga... :non:
