The easyest way that I have found to check the power switch is to trace it to the motherboard and disconnect it. Then with a small flathead screw driver you can make the connection between the two pins that the power switch was connected to. If the computer comes on then you know the problem is the power switch. If the computer dose not come on then you can forget about the power switch being the problem.

Were does the power switch lead go on the mother board on a rev1.1

If I am not mistaken, the green light stays on as long as the computer is plugged into 110v power source so that means very little. I would first check power button and wires from power button to mother board. But as with all computer problems it could be a lot of other things. Process of elimination.

Check to see if the power supply fan comes on when the power button is press if not you will have to open the pc and test the power connectors with a digital volt meter to see if you get the right voltage 5V (make sure to place your meter on direct current) or you can get a known good power supply and do a test. If you get the same problem the issue isn't the power supply. It can be an onboard device the next step is to remove all onboard device (memory,pci card, disconnect all drives etc)one by one as you move each device turn on the system. One off the device could be holding the system from starting. If you move all devices from the system while trying to turn on the system after each device is move and the problem still exsist you have a bad mother board and it needs to be replace
