My wife was using the computer earlier and when she was finished shut it down normally. She went to turn it on a little bit ago and it got to the grey screen with the apple and the thing spinning symbolizing loading I guess but it never loads to the desktop (sorry I'm a PC guy). I ran the hardware test on the OS X (holding D down) and everything checked out fine. I also tried holding down C and got to the screen where it ask if I want to install anything and I just click boot from HD and still nothing. Also tried taking the battery out and holding down the power button but that did nothing as well. I'm going to have to take this back to the store but does anyone know what the problem is?
