Computer Random Restarts

[StoveCold SteveAustin]

When I play games on my computer it just randomly shuts off with no warning or signal. I don't think it's my PSU because it shuts off at precise times. When I'm playing CS:GO or Skyrim it shuts off during loading screens. When I play BF3/BF4 it shuts off when I go to change my Video settings. I was looking at the temperatures and usage of my CPU while playing the games through HWMonitor and Task Manager. I never hit 100% on Task Manager and the temperatures average 50-55 Celcius. I don't know what else to do.

Computer Specs:
i5 4670k
GTX 760 4gb
535 W Corsair Power Supply
I also have a 212 EVO heatsink on my CPU.

I recently re-routed all my wirings so it's more efficient and has better air flow.

Weird. Your CPU or GPU may be overheating.
