Title:

Screen distorts and freezes, but show no distortions in safe boot.

Text:

The screen on my MBP 2GHz Core Duo randomly distorts the screen in a "chopped up" kind of fashion and freezes the machine. It happened for the first time about a week ago, the computer was fine the day after, but later the same problem reappeared. Now it is impossible to start it normally without the distortions. It mainly happens when there is some kind of motion on the screen, like a flash-ad etc.
The computer starts up fine in safe boot with no distortions or troubles, but on regular start up, the screen distorts when its about to show the login screen. Either in a "many layered squares with blue horizontal lines" way or as a gray screen with two black vertical "tire track" looking lines.
The distortions does not show on an external screen when it happens.
Is it the logic board, the screen, an overheating issue or something else?
The only thing I know about the condition of the computer is that is the battery is bad and should be replaced.
The logic board was also replaced one year after purchase.
