I'm having this problem for a couple months and i really can't seem to find out what's happening. It all started with fallout 4 and it always happened indoors (sometimes at specific locations repeatdly), then it ocurred a few times in starcraft 2 and now i can't play dragon's dogma for anything more than 10 minutes. Strangely enough, i've played witcher 3 for hours recently with no problem, it only happened once in witcher 3.

The computer turns off and then back on. A few rare times the computer turns on but no video shows up.
I've noticed there's a lot of people with 970s having this problem too.

I've ran memtest86, 0 problems
I've ran furmark, 3dmark and occt for a few hours and no crash
Sadly (or not) the computer is turning off with low temperatures.
my PSU is a corsair hx 850w

Turning down the resolution in dragon's dogma seems to alleviate the problem or even remove it.

My specs

mb is asus p6x58d premium
i7 960 3.2gb
12 gb ram gskill
GTX 970

I'm really pulling out my hair trying to discover what exactly is wrong here. Please help if possible.

It's a very good PSU i think, but maybe some circuit died. Wish there was a way i could be sure, good PSUs are real expensive where i live.
