Tom, Thanks for your suggestions!
Also, one of the first things to do is always to look at the event log.
Almost too embarrassed to tell what I think is happening.
I'm committed to partying until Monday, so I can't confirm until then
:-)
Watching the sensor outputs via Everest, I observe heavy CPU use
pushes CPU temperature up rapidly. At first I thought a bad fan, but
fan RPM's are bouncing around a bit but always between 2000 RPM and
2200 RPM.
So I think I'll find a CPU heat-sink fins filled with dust and cat fur
when I open up this box ;-)
What was happening _was_ Norton-induced... my idle time caused Norton
to go into idle-time-scan mode, pushing CPU up to 100%, and some kind
of thermal shutdown occurred.
That's the most likely diagnosis yet. It's entirely plausible and
explains just about everything, except for why the symptom seemed to
go away when you reset the power settings but that could be explained
as coincidence with Norton's scheduling of when it needed to run.
Yep. Just a coincidence to confuse things ;-)
We do tend to forget about the lowly heatsinks and fans but they can
and do get clogged, especially with pets around. I've opened systems
up to find the interior looking like the insides of a vacuum cleaner
bag.
One of these days I want to redo my office with wood flooring... that
helps quite a bit.
Of course my oldest son chides me to have rack-mounted PC's inside an
filtered air containment, as he does ;-)
Now that I've shut Norton down it's staying stable at a CPU
temperature of about 45°C... just like outside right now :-)
Useful utilities for monitoring temperatures and fan speeds are
speedfan and motherboard monitor.
