I have a 21.5, 3.ghz imac and does not get beyond the grey screen at start up. The chimes sound, the screen changes from black where there is no power to grey where it begins the start up process and then stops. It will not fire up in safe mode nor does it start with the snow leopard dvd inserted and holding down the c key. Any ideas what it could be.
