Techie question

[cheekbones3]

Hello all! We've got a computer that's just started switching itself off for no apparent reason - it seems like there's something wrong with the power supply as far as I can tell. Is this a common symptom of a worn-out PSU? And if not, what else might it be? (I'm sure it's not the external power supply equipment, as the monitor doesn't go off.

My first guess would overheating. Sometimes there is a cut off on the motherboard as well, so check fans, especially the CPU fan. If you have a case with poor air-flow, try taking the sides of the case off and see if that stops it from happening. Also see if you have any utlities for your motherboard/cpu to detect and report the temperature.
