Mysterious computer shutdown

When I use the computer for a while it shuts down completely without any warning. To start it again I have to shut of the power switch for a short while.

The problem seems to be temerature related since it works better if I open it and lead some cool air from outside into it. But if the problem is that the cpu is overheated, why do I have to shut of the power? It doesnt make any sense to me?

Athlon 1700+
help plz

Because these computers have more than a CPU.

The CPU is just one part. Other parts can become heat sensitive.

Since you did try the old cover off trick, what are you doing to replace, upgrade components to fix it? I start by adding 100 or more Watts to the power supply. Where do you start?

the mfr has included a sensor in the CPU to tell the mobo it's too hot and to shut the power supply down to save the CPU from being fried. Your question totally baffles me.

recycling of the power. That is done to reset the power turn-on logic circuitry, by removing the 5 volt standby power, momentarily, that is always on, unless one turns the power supply off.

Unless it is simply giving the CPU time to cool off.

The real subjecr should solving the overtemp problem.
