I'm currently on Macbook Pro #7. Lucky Number Seven. This one has lasted a year and two months. My screen started freezing. Anytime I went into Spaces or did something that required some transparencies, it went bluish glitchy. It did it several times. Fans would spin up, then Poof, it'd turn off. I then reinstalled Leopard, did all the updates, and removed the second monitor. The moment it went to a screen saver... that nice flurry one, it froze. I get "Graphics Channel Timeout" entries pop into the system log when I check it. The problem is... these problems happened RIGHT when the semester starts and I really need a computer that can crunch stuff for school. I've had incredibly bad and lengthy experiences with Apple in the past. I mean, long. Between 1-3 months per problem. Worst case ended up being almost 10 months because some one didn't issue me a refund. What do I do? Does the Genius Bar give out temporary laptops while they fix mine? I'm just getting sick and tired of this bullsh*t. Suggestions, ideas, HELP!?
