That's a classic symptom of the CPU getting hot; go get Motherboard
Monitor 5 or a similar product, install it, see what your CPU temp
is before starting SETI, then watch it when you start SETi. I'll bet
it climbs rapidly beyond 70C, then the system shuts down.

I would believe that too, if the crash happened a little longer than
0,5 second after SETI is executed. I don't have time to read anything
at all. SETI og Prime95 shuts it all down in a split second - also I
made this floppy disk with Linux, so I wouldn't need a hard disk to
run SETI - chaboomb - the machine crashes.

Sounds like your HSF has one of the following problems:

	Is not installed properly;

	Has come loose;

	Fan has failed;

	Fan power has come unplugged.

Remove the cover and verify that the HSF has not come loose--it should
not move at all. Turn on power, and verify that the fan is working. If
the fan does not spin, turn power off immediately. See if you can spin
the blades with your fingertip; they should turn easily. If they don't
the fan must be replaced. If they do spin, verify that its' power wire
is plugged into the proper type connecter and is properly seated.

If the fan works and the HSF isn't loose, then it's probably not installed
correctly--either it has no thermal compound, it wasn't applied correctly,
or it has a wax pad that failed to seat correctly. The HSF will need to be
removed and cleaned; the CPU will need to be cleaned (will probably involve
removing it as well), then reinstalled with the correct application of
thermal compound.

If the HSF used a wax pad, it makes cleaning everything more difficult.
It doesn't scrape off as easily, and generally needs a solvent to get
the last of it off.

Good luck,


Gary
