When attempting boot, only get a small blue photo of the world in the center of the screen which later turns into a folder after a few min. The fans run fine. No chime. Hard drive removed and tested good & able to read on another computer. G4 will not find CD w/ “C” held down and start up cd installed. I Reset PMU button. Installed another hard drive to attempt to reload software. Still cannot boot from CD Drive holding the “C” key during power on. I used IFIX IT USB device to run removed hard drive on another computer. The USB adapter is a beautiful thing! Any ideas. I bet new logic board is in my future. JOHN
The world symbol means it’s trying to network boot - (That age machine will not boot from an external USB drive - it must be a FireWire {IEEE 1394} drive). You may have bad cables/connectors failed drives connected at the HD and optical points. IF you share a System folder on your network it should show it as a boot source. That would allow you to proceed and see what else might be wrong. If this Answer is helpful please remember to return and mark it Accepted.
