I have a problem with the computer where I suspect the power button on the case is faulty, as it's been like this for a while now.... before if I pressed the power button 20 - 30 times it would eventualy boot and perform normally coupled with pulling the power lead in and out. Like as if it needed a surge of power before it could boot. It's been like this for at least 3 months, once I get the computer to boot the computer is fine.

Now it seems as if the button has completely gone, I have tried booting the computer using the power button on the main board, but nothing happens ... so I cannot confirm whether the main board has gone as I have never used the power button on the main board before.

As there are 2 wires entering the main power switch, does anyone know what voltage is running through them and ultimately would it be safe cutting the wires ... and then using a conductor such as a screwdriver to create a connection and initialise the boot?? :confused:
 
Yeah just use needle nose pliars or a small flat screw driver to quickly short the two pins on the motherboard, To replicate what the power button does.

The power button should work, its for system builders who don't use cases.
 
The on button is low voltage and all it has to do is briefly make a connection then break it.

That starts the computer going.

If you want you could take both wires from the switch and touch them together instead. If that doesn't work it's not the switch.


Or as stulid says, the wires lead back to some pins on the motherboard you could short to do the same thing.
 
Well there is power going to the mobo as the power lights are on, and I shut it down a couple of hours ago to instal a few updades, and now it wont go back on... its been doing this for a while now. Will give the screwdriver a go, cant imagine theres a serious problem, was working faultlessly couple of hours ago.
 
Touching the two pins with a screwdriver doesn't work? You sure you got the right pins? It's not the powerbutton if that's the case.

I agree with stulid pull out all the cables, get some compressed air in there and replace and then try. If still not, then try a new kettle cable, and another psu if you have access to one?

If all that still doesn't work then you've got a more serious problem
