H8-1360t
Microsoft Windows 10 (64-bit)

My H8-1360t has been working fine for about seven years.

Recently it developed a problem.  About one in ten powerups, on an unpredictable basis, it will immediately shut down...but then, without any intervention, a few seconds later will (all by itself) restart.  It will then work fine, for hours.

I've tried swapping out all peripherals (only a USB printer and keyboard and mouse), and swapped in known good hard drive, video card, RAM and power supply.   Replaced motherboard battery with a new one.  Even re-burned the BIOS with the HP BIOS install pack.

Checked Windows 10 for errors as well with its utilities such as sfc /scannow.

No difference.

I'm thinking it's the motherboard, and already have a NOS unused IPMMB-FM motherboard waiting in the wings (yes, I know how to get the Serial #, Feature Byte, etc. information into the new board).

My question is, before I swap the motherboard:

Am I omitting anything?  Anything I didn't think of?  Anyone see this type of glitch before?

Hmmm...as a last-ditch effort prior to swapping the MB, I replaced the item I thought least likely to cause problems:  the USB mouse.  It is a simple Kensington.

Weird.

Problem of shutdown-startup seems to have gone away...but it will take more cycles to be sure.  Perhaps the mouse has a transient internal short that, on being energized a second time, recovers?
