When _cold_ (meaning under about 55 degrees F), when the XP screen
fades in, the CPU fan comes on full speed and stays there, and
(I think) the CPU speed is throttled way back to reduce heating.
In any case the effect is that it takes 10 minutes to get a desktop,
and CPU utilization is 100% and stays that way for a couple hours,
with nothing unusual running. The effect of a slowed down CPU.
It's fixed by rebooting at any point. It comes up silently without
fan, and very snappily gives you a desktop.
Something about being cold (first boot of the day, for example, in
a cold room) kicks this off.
