[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.

Aye that could be I suppose, but it's been fine for a wee while.
