Default HP Pavilion p6120t will not turn on

My parents' desktop HP Pavilion p6120t refuses to turn on. Pushing the power button produces no response whatsoever: no fans, no lights, no POST beeps.

There is, however, a green light on the back of the power supply that flicks on and off quickly when the computer is plugged in, but slows down when the computer is unplugged. It stops turning on and off about 3 minutes after the computer is unplugged.

I have cleaned the dust out of the computer's innards and tested whether a stick of RAM was bad by seeing if the PC will turn on with only one stick in. Nothing changed.

Is the power supply bad, or am I missing something?

Unplug everything and hold the power button down for 30 even though it says 10 seconds in the above link. Reconnect and plug in the power. Reboot.

Edit: Also flip the voltage switch back and forth with the power disconnected.

Thanks for the link. However, I did everything HP's site told me to, short of replacing the power supply, and the computer still won't turn on.

Is there anything else that I could do, or is it pretty much certain the power supply is busted?

I would say it was a PSU. Is there a spare PSU you can install to check? Might be best to call around and see how much a shop charges to check a PSU.
