I have a MacBook Pro 15" A1150 (MA600LL) that will not boot except in safe mode. It gets almost all of the way through the boot then freezes with two vertical checkerboard lines and the trackpad-controlled pinwheel for a cursor.
Also, the chime works at the beginning, but after boot in ANY mode the sound preference pane says there is no sound output device.
What should I do?
Regards,
Don
