BSOD randomly

I have had this problem for about 4 months. My computer randomly bsod's. Sometimes when i alt escape out of games it freezes or does a bsod. I have two 5770's. I know one worked fine with my prior system and tried that and I got no BSOD/lockup. I have tested memory by using different memory modules and ran mem test 86 and the windows version and they were clear. I ran prime 95 for 24 hours without any problems. Also checked hard drive with the built i windows tester.

Extreme3 gen 3 motherboard
i5 2500k
x2 5770
seagate 500mb HD
650 earthwatt PS
hyper 212 cooler
windows 7 64bit

all temps are normal, could it be I dont have enough power? or bad CPU/motherboard?

Also i am not sure how how to get the large dump files - I tried with the debugging tools but I couldnt install after hours of trying.
