Hello, I have a macbook pro (late 2007-2.4ghz). Nearly a year ago I had my logic board changed as there were no display on the monitor though my computer was working. They said it is a production mistake and my logic board would be changed even if it was not on warranty. But now when my computer overheats a green vertical line at the left side of my monitor displays. when it cools this line disappears. I know 17 inch unibody macbook pros had same issue with 9600 gts graphic cards. My graphic card is 8800m gt. Is there a solution for that or I had to change my logic board again? Thank You.
