Need some advice on my Macbook Pro. Got it some time in April of 2006 and immediately noticed the CPU whine that was common with them at that time. After some fighting with Apple I had the logic board replaced under warranty just before the warranty was up (apr07). BIG MISTAKE, I should have left it alone. After a couple days I started getting video corruption. No big deal, it had a 90 day warranty on the new board, so I took it in again and had it replaced. Problems solved. Today, 5 months later I popped the lid and woke it up from sleep to find diagonal squares all over my screen..... crap, video card. Took it to the local shop and they estimate a $1200 logic board.... AGAIN. That will be the 4th logic board in this thing in less then 2 years. So here I am being held hostage by my logic board devouring macbook that is out of warranty. It's like a lemon car but worse. Help me!!
