Powermac G4 MDD Will Not Turn On After Freezing?

hi,
My G4 MDD was running software update and i left the room for a minute and when i came back, the thing was frozen and the mousr power was off. i turned the computer of than back on and the thing wouldnt turn on, the light would go on than fade off, also i had just insatlled leopard on it when this happened, this was the first boot of leopard, which was why i was running software update. since i wasn’t in the room at the time, i did not hear anything “pop”, also nothing smelled like burning, could it be the power supply, if so than this will have to be the 3rd replacement. this is a powermac G4 MDD
the mouse and keyboard as well as other usb devices had no power

the top awsner is completely wrong. if you press the power botton and it glows then the problem is the PSU needs to be reset. on your motherboard press and hold the CUDA switch (looks like a little bottom, possibly by the PRAM battery) for 3 seconds and let go. turn on your powermac. if you still get the glow then the awsner is a dead PRAM battery. they need to be replaced after every 3-5 years.

if the bottom does not light up or anything then the problem is most likely have to do with the power supply.
