Lafiel on 26 June 2012
I had similar issues with my PCs before. One time it was the power supply slowly dieing, another time the CPU fan was broken and a third time the thermal paste on my CPU was flaky and needed to be exchanged.
Even if the sensors tell you that there are no heat problems there can be hot spots that force the automatic shut down, if there is sth wrong with the thermal compound like in my last example.
