Guys, hopefully someone can help me out. I've been at this for 3 days and I'm not making any progress: I acquired a G4 MDD Dual 1 Gz processor Power Pc What happens is this: When I press the power button, it lites up, then goes off, then slowly lites up again. I get NO Chime. I do get Video, but I get the white/gray screen with the rotating little circle. And thats all. It never boots into OSX. I tried to reset PRAM, but it still went to the white screen. With no chime, its almost impossible to do anyway. The PRAM battery has been replaced. Both the little and Huge fans are spinning. The red lite on the MD is on. The two fans on the power supply are rotating and pushing air. The Memory in the box are Two Crucial 512MB DDR 400 CL3 (this is memory I had laying around, it did not come with the pc) MT 200401 I have pulled the battery, reset the PMU button, pulled all cards, memory, etc, to try and reset the box. nothing has worked. I never get a chime. Could no chime be a processor issue? Based on what I see, I am thinking its the dual processor board that is bad. I can a replacement fairly cheaply on EBAY. Do you guys think its the processor and NOT the MOBO? Or something else. ANY help is appreciated!~! Many thank you for any comments.
