Ok so I just replaced my logic board (did it my self becase my warranty was up & didn't want to send $1200 to have apple fix it). Now that it is replaced the computer works, but now I have these vertical blue lines going up & down my screen, i say it's erratic because some parts of my browser stays "normal" while other parts have these lines going up & down. After browsing through some of the discussion boards I am more confused then when I started, some people say it's a software issue, some say it's the screen & some say it's the NVIDIA graphics card. I ran apple's extended hardware test & everything comes up fine. If it is a software issue how can I resolve it. I also read something about needing to apply more thermal paste to the logic board. Again i'm confused & would like these lines to go away. Can someone please lead me in the right direction so I can finally have my laptop working properly & not need glasses! Thanks

    Without actually running any diagnostics all anyone here can do is "guess" what the actual issue is.
    Take your computer to an Apple Store. The staff will be able to check to determine if your model MacBook Pro is suffering from hardware problems. The diagnostic testing is free. If you are suffering from the dreaded NVIDIA graphics card issue, repairs are free also if you qualify - MacBook Pro: Distorted video or no video issues
