More information needed.

Update your post to include full system hardware specs and OS information.

Make and model PSU: wattage, age, condition?

If the computer is not normally turning on via the case switch then the switch could be broken or one of the wires serving the switch could be broken or loose.

What/where are you shorting the green wire to ground?
