So I've been experiencing this issue lately, and I'm pretty sure I narrowed it down to my GPU, where upon wake from sleep/hibernation or turning system on, at sign in screen or after logging in in about a minute or so, my system screen will go black, gpu fan will go to 100% and system will be unresponsive. If I hit the reset button, I'll hear the mobo post and beep once, but gpu fan will still be at 100% and displays will still be black. Until I turn off the pc with power button and power on again, it'll boot back up fine, system will otherwise operate as usual. No BSOD can be found in log.
I have also seen this same lock up when turning on or off HBCC memory option.
Anyone else experiencing this?
