If anyone knows if it was the motherboard or psu that caused this, It would be greatly appreciated.
PS. My specs are:
Raidmax 530 watt (not the best I know, probably upgrading to a corsair soon),
gigabyte micro atx am2 socket mobo that I dont have the name of,
sapphire HD 4890 vapor-X (stock),
phenom II 940 black edition(stock),
4 Gigs of mushkin ddr2 800 ram.
not sure what else is needed.
