I have a 2010 MacBook Pro 15" with i5. I was searching the web and all of a sudden my computer freezes. I force shut down and when it restart I get weird patterns on screen and won't boot. Goes one third of the bar and then restarts. Here's the epic part, if I place the laptop upside down, LCD on the desk and the bottom part 90 degrees from the surface and I take out the battery and the back panel from the unibody, it boots perfectly fine and got to use it but If I put the panel back it freezes again. Any clues??
