I built a new rig in Jan. 2016. It has been running great. Then a few days ago, my rig suddenly shuts off and starts up again. It does this immediately when I run a gpu stress test but some times it will do it just sitting on the desktop screen. I can remove the gpu and run a stress test and it stays up and running.

Everything is new. Here is the hardware:

CPU Intel 6600
Motherboard: gigabyte h170 d3hp
PSU: evga 650 p2
GPU: gigabyte gtx 970 xtreme

What would you guys suggest?
