My PC has developed a habit of running for a while, sometimes an hour
or so, then switching off instantly. If I press the on button the light
will flash but nothing springs into life.
I have taken off the processor fan and cleaned the matrix also. I've
had the power supply to pieces and spiring cleaned that. One symptom
that may point to something(?) is that if I pull out the power lead and
reconnect after an hour or so the computer will restart. If I leave the
lead in then it won't start at all.

Does this point to a power supply problem? Any advice will be greatly
appreciated.

Regards

Steve

If the CPU fan is working OK then yes I would say so, also make sure to
update your BIOS.

Thanks for taking the time to reply. The CPU fan is gusting well. My
knowledge falls down at talk of the bios. What would I need to do to
update it?

Cheers
