Hi all, I'm having a problem. I have a Mirrored Drive G4 Dual 1 Ghz. It seems to start up fine, I get the Mac chime but then nothing. I thought it might be my drive so I tried a start up disk and a repair disk, holding down the "C" key while starting up , get my start up chime but nothing else. I just replaced the Motherboard thinking it might be that but that didn't work either. Any suggestions.

Might not be the same problem, but I replaced the motherboard battery on my G4 with those symtoms and the G4 lives on

Do as louishen suggests and change the PRAM battery. MDD models are extremely suspectible to this behaviour with a dead PRAM battery.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Also make sure the graphics card is working - if you're not getting anything on the monitor...
