Help!,

when I boot up my macbook pro, it will go to the grey screen, then to the grey screen with the apple logo.

BUT then a grey loading bar appears at the bottom of the screen. It will load a tiny amount, and then the computer shuts down. This whole process takes about 3 minutes. Please help!

 

What should I do?


MacBook Pro, OS X Mountain Lion (10.8.2)
