My G4 wont boot up. After pressing power on, I hear the chime then it powers off. I xcan hear the hard disk running
After pressing power on, I hear one chime then it powers off. I can hear the fan & hard disk running, the CD starts to spin before it shuts down. Swapped battery, removed/replaced each of the 3 memory cards in turn. Nothing on the screen, in fact the monitor power light doesn't go from orange to blue so there is no attempt to send video to it. I tried brand new hard drive & got the square/question mark on screen... thought this was progress but can't get it to boot from the Operating System CD. any ideas?
