Total Loss of Power

Starting yesterday my PC will, after various lengths of
time, suddenly switch off as if the power supply has been
cut off.It will not restart unless I disconnect the power
lead at the back and then put it back in again.Does the
PSU have a thermal cut-out or the motherboard or both?
SiSoft Sandra does not report the system as running too
hot.
MB is Abit KT7A
CPU Athlon 1000 Thunderbird
512MB SDRAM

It could be overheating or it could be impending failure. That's a pretty
typical symptom of a motherboard with the defective capacitors that have
been going around.

It can also be symptoms of a power supply that is greatly underpowered for
the system it is in.
