I'm stumped and have tried everything so figure I would turn here. Randomly when gaming almost always at a loading screen or when tabbing in and out. My comp will instantly turn off and restart. I have gone over a number of problems I thought it could be.

Not the RAM.
I was running two 4 gig cards. Replaced them and it still occurred with the new ones. Now simply running both for 16 since my card can support it and I am running 64 bit anyway.

Not overheating.
I opened up my video card, cleaned everything out. Replaced the thermal paste and am running msi afterburner. I don't normally get about 70 degrees and it's done this as low as 46 degrees.

Drivers.
I just updated my video card drivers and it was occurring both before and now after a recent update 9/28/14.

Not the program.
So far it has occurred over three different games. Wildstar, Heroes of the storm beta and Archeage. so various publishers and a couple different game types... I haven't even tried BF4 since it started.

Scanned for Viruses.
Oh in addition I have run both Maelwarebytes and Spybot too scan for any viruses and the like.. No dice.

Current video card: AMD Radeon HD7900Series.

I have a Corsair HX750. When I built the machine in late 2012 I recall it being more then enough and I haven't added anything too it since then.

it might just be a faulty graphics card , try updating bios and restore to a time before it started to happen or re'install windows see if that helps,, your temps are still a bit high whats the rest of your specs?
