The green light is likely on the power supply unit, which means the power supply is getting power in. However, it may not be sending power out to the motherboard or other components. If you have a multimeter or voltmeter, you can check the power supply connections to see if it is putting out the voltages to the other components. If it's not, you'll need to replace the power supply.
If the power supply is putting out the voltages to all the connections, then the problem is another component, and there's a good chance it's the motherboard. You can check the connections on the motherboard too -- especially the one going to the power button on the front of the computer.
