G4 DA 533 1.5 ram x10.4 No chime at startup. Start button does not stay lit. Red light on motherboard. Fans run but no harddrive activity unless I disconnect the ribbon cable. Tried battery reset, reseating EVERYTHING, and starting without ram. NOW WHAT?
Well, you definitely can't start without RAM. I think sometimes if you incorrectly set the hard drive jumpers, you might not get a chime... though I don't quite remember if that's true. Did you recently adjust/install a new drive, or take one out? Make sure it's set correctly to either Slave or Master. You also might try replacing the ribbon (ATA) cable on your drive.
