Boots in safe mode but hangs at blue screen otherwise
MacBook Pro 15" Core Duo Model A1150 2GHz
My MacBook Pro started displaying strange colored bars all over the screen and then it hung. A hard power down and restart worked once, but the next time it did it, it got stuck with a blue screen. Now, it always gets stuck there. I can boot it in Safe Mode and it will boot all the way and display graphics just fine. The external DVI connector also works in Safe Mode. I can get into single user mode without any problems. What could be causing it to hang at the blue screen during a normal boot?
