I shut down this I mac this morning but when i tried to start it back up this afternoon I pushed the power button in the back, no chime; it when to the white screeen and the "spinning wheel" started, no cursor visable, then the Fan when on and the MAc shut down. I unhoked the power cord and the internet connection. retried but nothing changed.
would Zapping the pram or any other Key commands help?
