Computer randomly shuts down abruptly, then reboots
After moving to a new home, my computer started misbehaving. It spontaneously restarts, no error message and no BSoD. The computer abruptly shuts down as if someone pulled the power plug, then it reboots.
Important clues:
- The shutdowns happen at completely random times, nothing seems to trigger it
- Sometimes it happens during boot (which makes me think it is a power issue)
- Unchecking "Automatically restart" does not give a BSoD, shutdowns continue to happen abruptly
Things I have tried:
- Memtest86 ran 5 passes, 0 errors
- SFC /SCANNOW did not find any problems
- chkdsk command found no errors on any hard drive, including system disk
- Running two antivirus programs (malwarebytes/adaware)
