I'm getting similar crash but not BLUE screen of death but BLACK, BSOD. Happens randomly and cannot see any minidump files in C:\Windows\Minidump folder. I've unplugged my iPhone USB cord and another USB thumb drive but still get crash. It sometimes occurs in World of Warcraft game I play or sometimes just browsing web or just from boot up after Windows login. The only solution that has helped but not eliminated crashes is underclocking GPU using RivaTuner program. I need to hold down power button to power off and then press again to reboot EACH time it crashes. Not sure what to do since I cannot see any minidump info to post errors occurring. Please HELP!!
