    Hi everyone. I recently changed out a PS from my MDD Dual 1.4 GHZ model to my MDD 1.2 single GHZ model. Both PS were the same model except the 1.4 had some newer fans on it thus quieter so I swithed it out to my dual booting 1.2 model since I am getting rid of my dual 1.4 model. However, now once I hit the power button it clicks on for a sec and then shut rights off. Meanwhile, the other mac with the PS from the 1.2 powers and boots just fine. So whats up? I did add another HD to it but that shouldnt effect it right?
    Did I fry the other PS, changing it?

    Try switching them back. It shouldn't be too hard!
