My MacBook Pro crashed and won't restart
Today I was watching a movie on iTunes when the screen froze. I tried force quitting iTunes but it wouldn't react to control+command+del. When everything on the screen froze and remained that way, I shut down the computer by holding down the power. When I later tried to restart it would start making this screetching sound ending with a click and then go silent again. After some time a picture of a folder with a question mark would appear on the otherwise blank screen. Finally the computer would shut down by it self after some 30 minutes or so. Please help!
Much appreciated.
MacBook Pro, Mac OS X (10.7.3)
