So my wife asks me whats wrong with the iMac. Nothing I know of. SHe says the screen is all grey. She restarted it to try and get it working, and it returnes to the grey screen... So I check it out- sure enough, it is that grey weave screen that is the BG on Lion. The cursor arrow is there- and moves- but that is it. I figger at this point there is not a whole lot to screw up, so I power it down with the button. It powers down rather quickly. I wait 30 seconds and power up... I would say within 10 seconds, I am back to the grey weave screen... that is it- nothing else. Any ideas what to do here? Thanks!
