My PC, which was built yesterday has fully shut down twice for no reason while gaming. The PC would not turn on when I pressed the power button until I flipped power supply switch off and then back on. My GPU drivers are updated, Windows is Updated, no motherboard debug LEDs are on. CPU temps while playing are 60-70C and GPU 50-60C, Ram is in correct slots. I am a first time builder and probably did something dumb, please help.
