Try and install the mbmon port, and see if it works on your machine. If
so, start a cron job that appends mbmon output to a file say every 15
minutes. If it's a heat buildup issue in a monitored component, it would
I wonder though. My machine usually doesn't need a day to heat up after
a cold start. An hour or so usually suffices.
Other causes could be a spike in the line voltage due to a large device
switching on or off nearby. Or an underrated power supply overloaded
through a cron job.
Thanks for the ideas, Roland (and Tamouh)! I forgot about the possibility
of power issues. I do have an Antec power supply, 500W, which certainly
doesn't mean it isn't the problem, but it _ought_ to be able handle this
But here's what I get if I run mbmon.

That CPU temp is at about 97% idle -- high, no? The voltage on the 12V
lines seems pretty bad, and especially so on the -5V line. Should I trust
the sensors and think about a new PSU? In the meantime, I'll write to a
file, and see if it records a dip in power before the next reboot.
