New Build Restarting During Gaming

Hello everyone,

I have recently built a new PC and everything has been running smoothly until I have tried playing The Witcher 3.

Windows will randomly restart itself during playing the game, I have disabled the auto restart option in the system settings, but I still get no BSOD. It is as though the PC has just been turned off for a split second, but rather than going off and staying off it restarts.

I have also noticed occasionally that the screen will go blank but the PC carries on running, again, this is only during gaming, specifically The Witcher 3. I suspect that this points towards the graphics card, but I cannot be sure.

My CPU temp is not getting above 50 degrees and my GPU is sitting at around 58 degrees, I think that these temperatures are more than acceptable.

The PC was only built 3 days ago, so far I have tried reseating the graphics card, checking all of the power connections, checking PSU voltages in the BIOS (which are all ok), doing a clean install of the graphics drivers, uninstalling AI Suite 3 and using the cleaner tool (It seemed to be OCing the GPU) and changing the PSU power cord and plugging it directly into a wall socket.

Would really appreciate any suggestions as what to try next.

Specs are as follows:
Intel i7 4790k
ASUS Maximus Ranger VII
ASUS GTX 970
Corsair RM750 PSU
Kingston Hyper X Beast 4 x 4GB
 
I just built with an Asus motherboard recently, too. I had a similar problem. You say the temperatures are good, and they are. But you should check the bios settings since they could be set to low for the maximum temperature readings. Also, What OS?
Update: just wanted to add that mine wouldn't restart, it would just shut down. But then again, I have a different Asus motherboard.
 
I've had a look around into all of the BIOS settings, it would seem that on my board, it wont let me manually assign these temperatures, you can just either enable or disable thermal protection. This is on Windows 8.1 Pro.

I have not over clocked any of the PC parts, only turbo mode is enabled.
