My machine shut down because one of the fans went bad. I replaced the induction fan and the two extractor fans, I replaced the thermal paste and cleaned the heat sink.

Everything runs fine until it gets to 'Start Windows Normally' - then it shuts down again as if the same problem is still there.

On one occasion I saw the error 'CPU Overheat' just before it shut down. So I think the problem has been fixed but the machine is still in the error mode.

Is there anything I can reset?

Thanks - rev
