Yesterday morning I booted my machine up only to get a BSOD a short time later. getting BBcode 1a or 19 and 1-2 others. I tried to run the verifier.exe and when I rebooted, as soon as everything appears to be loaded my graphics now go haywire and the system freezes. The BSODs seem random, I've had one on a shut down. I was going to try memtest but since everything now freezes after a normal boot into windows I'm reduced to safemode. I can run anywhere from 5mins to 5hrs without a BSOD. I have attached the minidump files over the last 24hrs. I'm almost at the point where I am considering a complete format and reinstall of windows 7. Any assistance would be appreciated.
