Take the side panel or lid off the PC and try running the PC like that for a
while, if it is a heat problem then removing the side panel\lid and allowing
a better flow of air around the innards of the PC should stop any over
heating problems.
I had a mini tower PC which sucked air out of the PC via the PSU. Turned out
that the fan in the PSU was on its way out and only working at half speed,
fitted a new PSU and it solved the overheating problem. Apparently this is a
common fault with early AMD processors based PC's that run quite hot.
