[SOLVED] PC randomly shuts off

[HashtagGrandpa]

So this is a weird one and I am not sure how to fix it.

Spec list:

i5-3570k

Gigabyte GA-Z77-DS3H

8gb of ddr3 Patriot 1600mz ram

Gigabyte RX570 8gb

600w PSU



So whenever I am gaming/Using a few applications my PC just full turns off and requires me to unplug my PC for a few moments before it will power back up. I have ran a furmark and a prime95 stress test at the same time and I didnt see temps above 70c and my PC did not shut off while on full load, I have ran memtest86 and saw no errors, I fresh installed windows and it still does it. I am not sure what do to or whats wrong. Any help would be nice,

Try running MSI Kombustor and stressing the CPU at the same time for 45 minutes or so, if it will crash - PSU or VRM might be the cause.
Bonus: It will also heat up your room nicely
