PUBG Crashes my system


I hope someone can help to find the cause of my PC crashing.
The system is less than six months old

I play games sometimes, all of them except PUBG run great on 4k Ultra/High. But PUBG can sometimes cause my PC to suddenly shut down.
After such situations, I usually manually check the temperature of the heatsinks on the CPU and video card, but they are not hot - well warm, but not hot.
Also, after such a shutdown, I can't switch on the PC right away - after pressing the start button on the system unit, nothing happens. But if I manually switch off the power supply (with a switch on the power supply itself) and switch it on again, the PC starts immediately.

Games where everything is good:
- The Division 2
- Horizon Zero Dawn
- DayZ
- The Division 1
- The Invincible
- Hunt Showdown
- Ghost Recon Wildlands
- Red Dead Redemption 2
- Warframe

HWInfo logging was enabled from the start of the system, and after a certain period of time, the system was loaded. Log file is in attachments.
By load, I mean gaming PUBG.

I also attach some screenshots of HWMonitor with the load in some games (3 screenshots for each game - taken over a certain period of time each):

Horizon Zero Dawn
