    i have a power pc g5 dual with 4gb ram and 80 gb hdd!
    last week i installed tiger and downloaded some apps then turn it off and unpluged from wall.
    after a week i plug it in and hit the power button and nothing apears on my monitor,i only hear the apple chime. the light is white and thats it. i tried cleaning the ram,and also tried with one stick but nothing.
    any help why is this happening ? or how can i fix this ? id like to have some fun with it again :(

    Usual suspects, try a PRAM reset, and if that doesn't do it, reset the SMU on the logic board. I would also suggest testing the 3.6v battery and replace it if dead.

    Did you try the usual steps such as pulling all unnecessary parts (expansion cards, memory, etc)? Keep only the minimal amount necessary to operate the system.

    If you pull the side panel and power on the system there should be some LEDs which may help you diagnosis the issue.

    Sounds like you need to replace the video card. If that doesn't do it, your logic board has failed.

    I think they're (it?) is next to the edge of the motherboard right next to the RAM slots. Can't verify as mine doesn't seem to power on any more.

    Could the monitor have died? Or not be powered?

    You know...I think Apple did away with the diagnostic LEDs instead relying on the power light to indicate status. Though I could have sworn there was an LED on the motherboard that at least signaled some state of the system (such as the clear air shield not being in place).

    Also when you pulled the ram, did you leave a stick in on its own or 2 sticks in the matching slots between top and bottom ram sections
