Question Random PC shut down

Jul 4, 2019
I'm lost,

lately I get random PC shut downs and the behaviour is each time slightly different.

  • Everything started more or less 1-2 weeks ago where the PC turned off, while the GPU fans ramped up to 100% and kept on spinning until I shut down the power supply.
  • 2nd-3rd time it had a beeping sound and instantly after that it shut down and the same behaviour as first time.
  • 4th time it had one beep and after 1-2min followed by 3 beeps and same stuff as first time. (At this point i thought it was temperature related since I didn't hear the gpu fans before the incidents)
  • 5th time, monitoring the temp, happened without a sound it it occured around (~40°C) (so i don't think it is temperatur related)
  • 6th time happened while writing the thread and the pc simple restarted.
There was no error message any time, event manager does not show anything expect the errors that the pc was randomly shut down (but if i check the logs i don't see any real cause for that)
And now the MMC crashed when I try to do specialised logs... (system probably starts to break apart)

Hope that someone has some insight on what it could be.
