Question 2 years old problem

[KeeRub]

Hey,
so i have had my PC since mid 2018 and i have this problem where if i play a game i can only play for about 20min then my PC would start to make a really loud fan noise and i cant see anything on my screen but i can hear the game sound and i would have to hard restart it.
when i first got it i tried to overclock it but it started major problems so i reverted it. maybe my hardware is corrupted now because of the overclocking i really dont know if it's even related to that, or if it's a cooling issue or if my computer is not getting enough power.

SPECS:
CPU: intel core i5 7600k LGA 1151
GPU: Geforce GTX 1070
Motherboard: MSI z270 m3
RAM: Vengeance corsair 18gb DDR4
Power supply: Cool max 120mm 600watts

What are your CPU temps?
What cooler are you using?
18gb of ram? Is that a typo? I've never heard of the psu brand, so I doubt it's doing you any favors. A quick Google search shows some very negative reviews.

i dont know a lot about PC stuff but i checked temps and the max is set at 55 C and currently setting at 38 C
My cooler is: Cooler Master Hyper 212
The 18 was a typo yes sorry i meant 16 GB
and if my power supply is bad could you recommend me one that is good? i dont care about the price i just want to enjoy my PC
