    My earlier post listed the computer as a G3. My mistake. It is a G4 tourquoise tower. I believe its a PCI Graphics version. When I plug it in and hit the power button. Absolutely nothing happens. No light, no sound. If its the power supply box, is that something I can replace myself. How can I confirm the power box is dead and not something else.

    Thanks for your help on this.

    This may not be too much help, but you've checked that the socket works? Also, loose RAM can cause failure to start up, if it's been moved recently or the RAM has been played with it would be worth checking it's still securely in place...
