G4 "yikes" won't shut down!

[douglas]

When I try to shut down my G4 350mz "yikes", it goes to sleep for a few seconds, then turns on again. The only way to shut it down now is to pull the plug. Any ideas as to how to fix this problem?

USB

Un plug EVERYTHING excipt for the monitor and the power cable. Then plug all of your devices one by one. Shutting down everytime you plug a new one. You should find a solution from that.

Thanks, I followed your advice and the problem is with the usb keyboard.

Is it an Apple keyboard, or third party?
