I recently transferred my system into a new case - from a noisy rackmount server case to a whisper quiet desktop.  The transfer went smoothly and all data and applications are still operational.

 

Ever since completing the transfer I find that the server is randomly shutting down.  The periods in between shut downs are not regular and are far apart - from a couple of days to a week.  The system is sitting at my daughters house as I am currently working remote and I honestly thought the cats were walking on the power button.  But I've now covered that button and it is still happening.

 

Rebooting loses the logs - so I don't even know how to begin researching this.

 

The only other weird thing about my new build is that I cannot reboot it without relocating the USB boot drive.  It simply won't boot unless the boot drive is moved to another plug from the last time it ran, then it boots fine.  I'm including this because it is an oddity that might provide a clue.  I believe the system is rebooting, not shutting down.  Because of this weird issue with the boot drive, it can't complete the boot.

 

I'm interested in any advice on where to start troubleshooting.  Thanks.

Go back to the old case and start over.

If the server really shuts down, it suggests some hardware issue, but you can enable the syslog server and post that after a one to confirm if something is asking for a shut down..

Difficult, since its rotting in a land fill.

Thank you, I wasn't aware of this ability.  I'll set it up today and start monitoring.
