The light is not on too

Answer 1

NOT necessarily the power supply. Sometimes it is just the power button. You can switch on directly through the motherboard pins that connect to the power button. Just take out the connectors, then briefly short w/ a screw driver. If power supply fan does not even turn on, then it could be dead.
