Good advice, but I've already tried that.
I believe I have two separate unrelated issues: Freezes and reboots.
I have picked through Power Management settings also, and set it to never
sleep. Also went into the BIOS and tweaked power management here and there,
to allow the computer to wake on any event. I found settings in the BIOS
that were disabled for everything that would wake the computer after it
slept. The freezes were acting just like sleep state, but with no ability
to wake up (monitor blank, laser on mouse turned off, etc.).
So I think I have fixed my "freeze" issue. Now if I could just find out
what causes it to reboot uncommanded... but that may yet be a hardware
issue...
When it happens, I hear nothing... just *poof* black screen and reboot, just
like on a commanded restart, but without all the hubub and disk activity of
a shutdown/restart.
I know it is not the power supply, as the BIOS will not allow a restart on
power loss. I don't think it is the disks, as I don't have any other
indicators, and have scanned them all thoroughly. I suppose it could
possibly be a VGA/PCI card, but my thoughts are on the mobo or ram.
One final detail. It usually only happens during periods of inactivity.
But sometimes that inactivity is only a couple of minutes, and varies so at
other times it is more than several hours.
There has been at least 4 uncommanded reboots this morning sitting next to
my workstation.
