System specs (not overclocked):

AMD Ryzen 3600 CPU
MSI B550 A-PRO Motherboard
HyperX Fury 2x 8Gb sticks
Nvidia GTX 1060 3Gb Graphics card
Corsair TX650M Power Supply

I also have one 2tb hard drive and one 500gb SSD

Desktop PC keeps randomly rebooting, have checked Event Viewer, and every time it gives me one error event and one critical event, the critical event always comes first:

Kernel power, Event ID 41, Task Category : 63.

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.


This is followed seconds later by this error:

WHEA-Logger, Event ID 18, Tast Category : None.

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 8


The details view of this entry contains further information.

The reboots seem to mainly occur when I am idle (browsing on chrome, listening to music) but they have previously happened once or twice whilst gaming also. The reboots seem to occur less frequently when my power plan is set to Power Saver, as opposed to Balanced, or AMD Ryzen Balanced. The screen just turns off randomly, no colour just goes black and audio continues usually in a distorted fashion for a second or so.

Solutions tried:

  • Updating BIOS
  • Updating drivers
  • Have run memory tests multiple times, and GPU intensive tests
  • Run Windows system file checkers
  • Changed options of power plans such as when my hard disk and display go to sleep etc.

Please help!

How old is the PSU in your build?

Updating BIOS
Did you clear the CMOS after verifying that the BIOS was successfully updated to the latest version? As for your BIOS, it'd be a good idea to mention what version you're on.

The PSU is a replacement of my old PSU. I replaced it as a way of troubleshooting the issue, obviously to no avail. The PSU is around 10 months old id say, maybe a bit older.

With regards to the CMOS, I dont really know what you mean. I'm fairly inexperienced so would be great if you could help out more. The bios I have just updated to is MSI's 7C56vAE.

Thanks
