    what is the most common cause of the G5 starting up with no chime and then not displaying video? It seems like the causes are widely varied.

    A video card problem or a memory issue.

    Power Mac G5 boots fine without graphics card, so if it shows up in your network, there is your answer.

    If you see that power led blinks few times after power on, that is RAM or memory controler / dimm slots on logic board.

    Else: logic board.

    Perhaps we could assume common sense. The power button lights up the chime does not occur. I've determined it is not the video card it's either bad ram or the logic board. I ordered a new G5 to replace it for now.

    Thank you Detective Sherlocke.

    TRUST ME - Part of my job is to help people out at work with their IT, you'd be suprised how many people complay their PC or laptop won;t start up when either the battery is dead or someone has unplugged it!

    There is a website that had a solution to this I saw recently - https://happymacs.wordpress.com/ - they have an article about a special switch inside some G5's that allows a force restart of the power system on the machine and this can sometimes make them work a when there's no start-up chime.

    G5s are a special (and aging) machine. There's a lot of specialist knowledge in this sub-forum on the G5.
