Uh oh. I was playing Witcher 3 for about 3hrs today at stock speeds (SLI) and not only did I get one screen blink (albeit after playing for well over 2hrs) my PC even powered down. 😱
Now I have to try and figure out what's going on. The log doesn't show anything wrong and the GPU power seemed not to be over 65C from what I could tell (I'll have to keep a log next time I play).
Last time I had a shut down like this was during the Winter and I was running a space heater on the same circuit as my 3-way SLI OG Titan setup, and I assigned it to that. That might not be the case now. It could be my OC i7-3770k is getting too hot @ 4.4GHz. Either that or the new 980Ti's are getting too hot. Maybe a bad PSU? I have the top of the line 1200w HCP-1200 Antec Gold, can't beat that. I don't really know at this point.
It still could be I'm drawing too much power off the same circuit. I'm using an overclocked PC with 2 980Ti's, a 47" TV and multiple devices, another HDTV, home theater, etc, etc. But that still wouldn't account for just the PC shutting down? Would it?
