Comp automaticly powering up.

[johns-andy]

Family member turned my comp off the other night when i was at work.
Turned it on the next morning once i was done.. boot screen but then screen turned off saying there was no input... fair enough.

Held the power button in to turn the comp off.. no joy.
Reset button no joy..

If i flick the switch on the power supply or take the power lead out it turns off obviously.. but as soon i as put it back in or flick the switch it automaticly starts up again but doesn't boot up.

Thought the power button may have been jammed but i disconnected all the LED, Reset and Power button cables and it still powers on when the power supply is powered on.

Any ideas? i'm stumped.

no one?

yes.. ignore the whole monitor situation. when power is connected all the fans run.. even without turning it on. \i've disconnected the pwr sw button

No monitor output to check the BIOS...
Tryed plugging it straight into the wall but still the same, automatic turn on when psu switch tuned on.

I'm awaiting a shot of a PSU tonight to check. That'll prove that at least.
