Sudden PC restart?

Question

Computers

Hello. There was a problem with the PC, when using it, it suddenly reboots, and this happens at different intervals and at different loads. I monitor the temperature through Aida 64, everything is in order there, it does not knock out any errors or a blue screen of death. In the Windows event log, after a reboot, I see such a critical error (kernel-power), I attach a couple of screenshots from different reboots.




The question is, what could it be, where to look for the problem? Can you tell me some utilities for testing a PC in such cases?

Answer 1

There are many options) you can hardly find anything with utilities, start by rearranging Windows. Then look at the hardware, start with RAM, if 2 bars leave one in turn and test

Answer 2

The name of the error speaks for itself. Kernel-power - a power problem.
Such an error and the spontaneous shutdown of the PC without a BSOD for the first time indicate power problems:
1. The most likely cause is the PSU. There can be 2 main problems with it:
A) Swollen capacitors
B) Overheating due to dust/dirt or fan failure.
2. Next come the problems with the motherboard.
If it is ancient as mammoth excrement, and there are electrolytic capacitors on it, then look at them first of all.
It is easy to determine the overheating of the power supply unit, just touch the case of the system unit in the area of ​​the power supply unit immediately after turning it off. Or the body of the PSU itself. It will be hot, not even just hot, but very hot, most likely even the hand will not be able to withstand it.
This is the first thing to check, there is no need to do any reinstallation of the OS yet.
