G4 goes to sleep, won't wake up.

It goes to sleep for no reason (when I'm working) and then won't wake up. Push the button, light comes on when you hold it, but no boot.

If I disconnect the power and unplug the flatscreen monitor and wait for twenty minutes and try lots of times I can get it to re-boot. Other times it just won't boot after being off for the night. It seems to do somehow with the monitor? Makes no sense. I have it set now to no sleep and leave it running 24/7 It's driving me nuts. Anyone run into this? Thank you for any help.

Sounds to me like you need to take advantage of that warranty service before your last month of warranty runs out.

I've found that when I have a bad firewire cable (i.e one my cats have been trying to eat) my Mac can shut down. You might try disconnecting all firewire and usb cables and see if that makes a difference.
