Did you change any components or settings before the issue occurred?
Does it also auto reboot on bios 1403 with bios all default settings(no OC)?
No changes. The system is host to two VM's one server and one desktop. It also serves as the primary data repository. Live data, larger disk with archive data that syncs with live data and syncs with disks on two other systems. Then larger repository disk that is archive of the archive and backups of VM's all systems.
This box was a pillar in my 'community'.
When I added the new OS disk, I set the most current available bios to default and did the install.
so far it does the reboot thing and records no anomaly's different than above.
I will add that on the initial purchase of this board it was delivered with a failed bios. Asus sppt could not find a way for me to update it. Advised I return the board. The second board worked as expected. Wary I did not update the bios on this board until I had these issues. I allowed Armory Crate to deliver drivers. Due to errors present in the Winsys log where Armory Crate was suspect, I had uninstalled it during trouble shooting. On the new system the "default" I modified in the bios was to disable Armory Crate. I downloaded and installed the drivers for the system manually.
These 4 items remain unidentified, and the box still randomly boots recording the events indicated in my initial post each time.
Thanks again for thinking on this. I have not been able to find a way to record more information that could lead to a clue as to why the system is rebooting in this strange manner.
