Steinar,
I have seen this problem occur when there was a problem in one of the
chipset chips. These chips can (In some, but not all cases) generate a good
bit of
heat when running a resource intensive program such as mprime, AND if there
is a small flaw that has occured (Which can occur after a year or so of
stable use.. I had a old P133 that ran for a year and a half perfectly..then
this problem happend and it went on limping for about 6 months before finaly
dying) and causes a fault when it overheats. Unfortunatly there isn't a
way to measure their temps. other than touch (BE VERY CAREFUL or you could
damage your computer when touching in the wrong place) or a pyrometer.
>From the sound of things, I would place my money on that being the problem.
Sounds like your CPU Fan is doing a great job at keeping it near room temp.
(FANTASTIC for when runing mprime).
Hope this helps,
Jeramy
