Calling all experts! I've been having ongoing BSOD issues since installing a new 6770 a few weeks ago. Long story short, I did a fresh install a few days ago and I'm still getting BSOD's.

Below are links to my latest minidump file and CBS.log from system file checker and the specs of my system.

My first guess is that you have a possible PSU issue with the GPU that you installed.

* Did you only use the onboard GPU until you installed the 6770? If so than it could be the PSU, but is possibly the GPU, not 100% sure. Your PSU shouldn't have any issue powering the 6770, but it's something to check out if you have a spare PSU available.

Thanks for the reply. Is OCZ known to overrate their power supplies? I got the impression a 700W, even if overrated, should be ok. Unfortunately, I don't have a spare to swap in. The latest BSOD points to dxgkrnl. Any suggestions?
