Question Computer shutting off while playing games

[keeblerelf2]

My computer has been turning completely off while playing games, usually after about 5-10 minutes. No blue screen, just shuts off like I unplugged the power cable. It started when U installed a new CPU/Motherboard, but i’m not sure which could be causing it. Not power supply, have tested 2 and it still happens. Not overheating, crashes usually happen in the 35 a 40 c range. Tried installing different CPU but computer wouldn’t boot. Haven’t tested different motherboard yet, would that most likely be the issue or would it more likely be the CPU, or even a different component?

Specs:
Intel i7-8700k
Asus STRIX z390-e motherboard
evga 1070 ftw gpu
16 gb corsair vengeance ram
evga 850g3 psu
nxzt kraken cpu cooler
1 tb samsung evo ssd
playing at 1080p, if that makes any difference

Have you Try to clean uninstall your driver and reinstall your gpu driver?
I have the same experience while i change my gpu, i did uninstall and reinstall my driver with DDU Software and now my pc was okay.
