When I push the power button on my G4 It glows and then turns itself off. I can't go beyond this point. I tried inserting the OS system, but that a no go issue too. What can I do?

I'll defer to the experts, but this could be a firmware detected failure, and it shuts itself off, or it could be that your power supply is faulty.

Try unplugging it from the electrical socket for 15 minutes or more if you can. Then plug it back in and start it up.

If there is still no joy, take a look at these Apple Knowledge Base Articles:

Resetting your Mac's PRAM and NVRAM

Troubleshooting: My computer won't turn on

Let us know how this goes for you.

I reset the Cuda Chip and that keep my power on. Great!
But now I back to my original problem which is: the apple icon stays on for a long time then, I get a blue screen with any icons. The last thing happens is a black screen with a small white retangle in the upper left corner of the monitor. Is this a sign of crashed hard drive?

Problem was solved when I reset the Cuda Chip located on the right side of the battery and that keep my power on. Thanks to MACHEADCASE

Yes, the apple icon stays on for a long time then, I get a blue screen without any icons. The last thing happens is a black screen with a small white retangle in the upper left corner of the monitor. Is this a sign of crashed hard drive?

Ok can you list the Mac OS version you are using and the model of the Power Mac G4 you are using and the specs? Be specific please (example for OS version: not Tiger but 10.4.3 for instance). This would help us in seeing what could be wrong here.

Till you give us more info, I came across this at Apple's: Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier).
