Ok so over the past couple of months my computer randomly shuts off when i play games. It is definitely not any parts over heating because i monitor my temps constantly while playing. CPU temps have never been past 55 degrees C and gpu temps never past 80 degrees C. I've tried everything, ive cleaned it, taken it to a shop and they ran a full diagnostic on it and found nothing. It makes no sense because when i stress test it doesnt shut off, but when i play a game it does. I dont think it is a virus because i formatted my hard drive. I dont get any blue screens on shut down. It just turns off as if my power went out then turns right back on. Not over clocked, reset bios and also cleared CMOS.



Specs:
Asus Sabertooth Z77 MOBO
Nvidia geforve gtx 670
16 GB Gskill ripjaws Z series
Corsair H100 liquid cooled
OCZ Fatal1ty 1000w
corsair 800d (overkill)
1 tb hard drive
Kingston hyperX ssd
and a dvd player thing

Is there any way for me to test my power supply or the power/reset switch?
