TL;DR: Sometimes my PC restarts 2 times instead of waking up, at first there's no display output, then there is, then it restarts one more time. The time in Windows is wrong and there's nothing in event viewer. My PC also sometimes restarts by itself (Machine Check Exception; Cache Hierarchy Error in event viewer)

Hello,
sometimes (about once a month) when I wake up my PC from sleep instead of normal behaviour it does this (always in this order):

  1. fans start to spin but no display output for about a minute
  2. it turns off
  3. after 5 seconds it turns on
  4. fans spin faster but no display output
  5. fans spin slower, no display
  6. fans spin faster, no display
  7. fans spin slower, Asrock logo appears
  8. after 10s Asrock logo disappears, fans spin faster
  9. fans spin slower, Asrock logo appears (with the keyboard shortcuts for entering BIOS in the bottom right corner), BIOS keyboard shortcuts disappear and the Windows 10 loading wheel appears, the PC boots, but it takes shorter to boot than normally, in the event viewer it just says it has entered sleep and after about a minute it has woken up
  10. after booting the time in Windows is wrong, sometimes it's wrong by 20 minutes backwards, sometimes by a couple of hours (might be the last time when I put my PC to sleep, not sure though, also when I sometimes - not immediately after this problem occurs - check the time in BIOS, it's correct)
When I usually turn on my PC (after shutting down normally), the fans spin faster, then they slow down and then the Asrock logo appears (first with the BIOS keyboard shortcuts, then with the loading wheel). So when this "problem" happens, it looks as if the PC rebooted 2 times without display output, then once with display output and then it boots.

I tried to reset BIOS settings (BIOS is not updated), uninstall some software running in background, change power plans (however I did not try changing settings such as hybrid sleep etc), disable global C-States, update drivers and Windows, nothing helped. I haven't tried changing the CMOS battery, but the PC is only 1 and a half years old so it shouldn't be a problem.

I don't know if it's related, but my PC also sometimes restarts by itself without BSOD (sometimes it's once a month, sometimes 3 times in 3 days in a row, however it has not happened in the last 4 months) and in event viewer it says:

A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 0 or 1 (this number changes)



Specs:
Desktop
CPU: Ryzen 5 3600 (stock clocks)
Mobo: Asrock B450 Steel Legend
BIOS version: P3.20
RAM: Corsair Vengeance 3200 Mhz CL16 (XMP off)
GPU: GTX 1660 Super 6GB
GPU drivers: Game Ready 511.23
CPU cooler: Arctic Freezer 34 eSports One
PSU: Seasonic Gold GM 650W
Case: Corsair Spec-Delta
SSD: Kingston A400 480GB
Age of my PC: 1 and a half years

Thank you for your help!
