Random PC reboot in several games, what to do?

Question

Computers

There was a problem, a couple of months ago I assembled a PC. Everything was fine until I started a game like rising storm 2 vietnam, the computer started to reboot during the game, this can happen after 10 minutes of the game or 30, in general, randomly. Okay, I thought. A little later, I said the beta version of New world, where it did not have time to turn on before the menu, as the PC went into reboot. Also dick with him, I thought, beta all the same. Even though I was starting to think something was wrong. And now I have an insurgency sandstorm. The problem is the same, the game does not have time to reach the menu - reboot. But after a couple of attempts, it worked, but now the problem has recurred, although the reboot already occurs at the time the server starts.
In other games everything works, there are no problems. The PC is new, all components are new.

config:
Mother: ASRock B550M Pro4
CPU: AMD Ryzen 5 5600X
Video: Palit GeForce RTX 3060 Dual OC 12GB GDDR6 NE63060T19K9-190AD
RAM: HyperX Fury 2x8GB DDR4 PC4-25600 HX432C16FB3K2/16
SSD: Samsung 980 1TB MZ-V8V1T0BW
PSU: DeepCool [DAB070DA0] DeepCool

Answer 1

I would, first of all, sin on the BP. Surely overload on the power of the video card, if the problem is only in games. If the video card is now connected to the PSU with one bundle, then you can try to specifically connect it with two different ones, from different PSU connectors.

Answer 2

Reloading under load is the first reason, processor overheating. Put some OpenHardwareMonitor, turn on the logs there in a file and see what happens since the reboot
. The second reason is problems with the power supply, which at the moment of increased load cannot produce the required voltage and everything turns off.
In pursuit, drivers, viruses, etc. check. I hope you don't mine in the background?

Answer 3

Check and replace, if possible, the thermal paste on the processor, also try RMB on "This computer" - Properties - at the very bottom Additional options - in the footnote (Download and recovery) Options - uncheck "Perform automatic restart". Try, if possible - run games with a different PSU .. Run any stress test on the video card and separately on the processor to check, not for a long time. You can also try resetting the BIOS settings to default.

Answer 4

The power supply is good. Bronze 80+. (I would even say with a margin) If we assume that everything is new, then it can be excluded.
Download the load test and run the entire system for overheating.
Check separately:
1. CPU.
2. RAM.
3. Video card.
Go to bios and see what settings are there (in terms of temperatures).
Reboot, this is a critical situation: either PSU protection or Bios.
Windows would show a blue screen.
Agree with previous answers: Very similar to "Overheat". And of course, we proceed from the fact that the CPU Fan is correct and correctly installed (paste, setting in BIOS and all that).
