system reboot

[Sanford Aranoff]

I leave the computer on all the time. Sometimes in the
morning I notice the system rebooted. Automatic reboot is
unchecked. No error logs. Any idea what happened? It
happened last night, which is early Wed morning (or late
Tues evening).

Hello,

Power trip?
Power cut?
Loose power cable?

unchecked. No error logs. Any idea what happened? It
happened last night, which is early Wed morning (or late
Tues. evening).

There were some Windows automatic security updates Tuesday; mine had
restarted this morning also.

There was a note in an a/v letter I receive that an unscheduled Tuesday
update was coming.. usually they're sent out the second Tuesday of the
month. This isn't the same article, but one I found with a Google search:

Why can't I find out about the security update from event
viewer?

Why didn't yours show this? Perhaps you didn't receive this update.. it
was merely a suggested cause of the reboot.
