Jan 12, 2012 8:27 AM in response to Alexanderby WZZZ,Try an SMU Reset. Without knowing your model, I can't suggest which one to use. You could search using "SMU Reset site:support.apple.com." If it's an iMac G5 it's this.

Jan 12, 2012 9:13 AM in response to WZZZby WZZZ,Also, do you get the chime when you boot? How old is the computer? It might need a new PRAM battery (clock battery.) If dead in some models, will prevent booting. Average lifetime of this battery is five years.
