hmm... I did a stress test with aida64 for 1hr no BSOD. With the GPU stress test incorporated into the test the computer gets really slow but 12v voltage never dropped below 11.808 and 12.094. However majority of the time it was below 12v's at 11.8-11.9v for long periods of time when everything was being stressed.
I didn't see anything about the CPU throttling via the graph and the CPU never went above 70 c temp. Infact all temps where fine.
The pc really only bsod's during gaming. And has trouble running Payday 2 which it shouldn't really have trouble with. Memory tests always come back ok although I haven't done one recently that has never been the cause of this problem. I need to check a few bios settings maybe that played a roll...
