Interesting. I had the same experience with a MDD DP 1.25 pre-2003 ($1000 at the time). Replacing the PS didn't fix it. Took it to Apple store. Genius said the processor was shot. Replaced the processor with a good used one...no go. Figured when it went, it took out the mobo or vice versa so I put in another used mobo with my old processor. Nada. Replace processor with the good used one. Ta-da! I guess both items were toasted. :-( -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
