(I've already recommended "Blank Screen Only" in the post Eric replied

I'm having a bit of trouble parsing that. Are you saying that if the
computer is sitting there, with no-one logged in at the console, and
there's not even a screen saver to burn CPU cycles, then the computer
is basically idle, and you suspect that the problems might be load
related?

I'll take your word for it that the computer is idle if no-one is
logged in at the console (it's certainly not true for all Unix-like
systems).

It sounds like a recent Pentium 4 or Celeron machine. These are known to
be (electrical) power-crazed, and can output a *lot* of heat. But they
have thermal protection in the CPU: they throttle down speed and power
consumption if the temperature gets too high.

I suppose that it *is* possible that on a badly designed system the
extra heat from a loaded Pentium 4 could induce temperature related
problems in the rest of the system.

But my money would still be on the screen saver (if I was a betting
man...)

This sounds like an ideal candidate for the SETI at Home client, or
something similar: get the machine doing useful work in the background,
and see if it affects system stability.
