    Hi there,

    My Power Mac (2x2GHz G5, Late 2005 model) is acting strange since a couple of days when I want to start it up. When I press the power button the white light comes on for a short time and goes off again. When I press again and hold the button the white and the red light come on, usually also the startup chime sounds, and then the lights go off again. When I repeat the action the computer eventually starts and boots normally and then works normally. Sometimes it works already the second time, sometimes I have to try more times.

    Does anybody here know or have an idea what this might be and wether I can repair it myself? Thanks for your help.

    did you do any re-installs of your OS anytime soon? ad additional memory?

    could be faulty/conflicting memory. if so remove any recently added memory and go with the bare minimum and see if it runs.
