Boot issues and UnRaid spontaneously turns off

[smick]

I have been running 6.9.2 for a long time. I now updated to 6.11.5 and initially it wouldn't boot but eventually I got it to work except Win10 VM won't start which I think is a separate issue.

 

Now after being on all day my computer spontaneously powers off. It didn't shut down just turned off the power. Before I got 6.11.5 to boot, I'd reboot the computer and get nothing - no text at all like the BIOS didn't start. Finally I restored the old 6.9.2 and got it to boot. I then updated to 6.11.5 and everything seemed stable except the Win10 VM wouldn't boot.

 

Now my computer spontaneously turns off from inside UnRaid consistently and when I try to reboot its back to the no BIOS type issue with no text on the screen. Eventually it powers off. I have been able to pull the flash drive and insert it after the BIOS starts and got it to boot. Then in a short time it turns itself off.

 

About a year ago I had an issue and posted to the forum and it turned out it was my power supply which I replaced with a Corsair RM750x. Does this sound like another power supply issue or is it related to the upgrade?

 

Any help appreciated.

Here's my diagnostics from earlier in the day when it just had the Win10 VM issue.

This suggests a hardware problem.

I suspect the power down issue is related to the bios. I had the issue booting UEFI. Booting legacy mode is stable.

I found the solution: Settings -> Sleep Settings were enabled. It was "sleeping" shortly after I booted UnRaid. This happened after upgrading to 6.11.5. I may have been booting in UEFI rather than legacy without realizing it and the feature just didn't work in legacy.
