Question Cpu overusage turns off pc? How to fix?

[alen1]

Hello guys i'm playing COD Warzone, and sometimes my pc turns off (after 1 min or 30 min or 1h). It doesn't matter if i have high settings or not... the game runs smoothly but ends up turning off my pc. COD uses 40% to 80% of the cpu. I tried using razer cortex for background apps but nothing has changed.

i7-4770k 3.50GHz
Radeon rx 480 Graphics 8gb
32gb ram
