Computer shuts down after some minutes

[plutomaniac]

There are some cpus that run hotter. This specific one I searched and it should operate between 70-75°C at load. No more than that. Newer generations run cooler. There could be other factors that cause problems:

A) Bad case cooling, more fans needed with correct airflow or bad cable management that does not let the heat get away.
B) Defected or malfunctioning power supply..

Can you provide us with a picture of your computer(inside of course, at & around the cpu area)?
