Computer shuts down after some minutes

[Googolplex]

Most probably you have forgotten to apply thermal paste to the cpu and it shuts down because of overheating. Or the cpu fan is not working. Moved to offtopic and changed title since this has nothing to do with AAMFP.

I do not have forgotten thermal paste. My computer is mount correctly and free of dust. My bios shows me CPU temperatures of 79°C after I turned my computer on again. I think it was over 80°C in a game. But why Amnesia doesn't cause the problem while Among the sleep or Dear Esther do?

Normally this thread was meant for AAMFP about engine updates, perhaps FG would say something about it.

I have to buy a new PC now, waiting for Haswell CPUs.
