PC Restarts Randomly

[metanner112]

Almost every other night my pc has been randomly restarting during a game, so far it's been during Overwatch and R6 Siege which are not demanding at all for my build. No blue screen when it restarts either. Pls help.

Straight up rebooting with no BSOD or errors indicates more likely a hardware problem.

Are you overclocking any hardware?
Is the restart random or at specific points within the game?
Does it only reboot during gaming?
Have you checked that temperatures of your CPU and GPU are not too high under load?

Sometimes this can be a faulty PSU too.

Thank you for your reply. I have nothing overclocked, the restarts have only happened during gaming at random moments. My CPU has been around 50 degrees celsius while my GPU has been around 70 degrees celcius while playing these games. I'm leaning more towards PSU.

Firstly I would ensure that you have the latest GPU drivers installed as per your manufacturers website. I would expect drivers to cause a BSOD, but it doesn't necessarily always happen.

If you access: Start > Event Viewer > System Logs - are there any errors around any points that your PC shuts down?

You can likely use 'hwinfo' to do a basic check as to whether your PSU is distributing the correct voltages.

My GPU drivers are up to date. I have found that I have several Kernel-Power Critical errors. They are all around times I have turned off my PC which is interesting. I always wait until my fans stop and then I flip the switch on my PSU. Could that be an issue? What are considered the correct voltages?

 

[PC Tailor]

Kernel Power critical errors are normal, they're errors effectively saying that power was suddenly lost, this error occurs anytime the PC sudden switches off. So they're not showing the problem. But there are no other errors asides the kernel power ones?

No, that shouldn't cause an issue. You should be able to identify the exact voltages from the PSU manual, the motherboard manual (where it indicates the 24 pin slot), or just lookup online. Generally they're all the same: https://www.lifewire.com/power-supply-voltage-tolerances-2624583

No, there are no other errors. I recently reinstalled Windows onto my PC and it has not restarted until 5 minutes ago from when I post this. During Rainbow six, my temps on both CPU GPU and motherboard were all normal. I don't know what it could be.
