Okay, I've been having an odd problem with my Macbook Pro (Core2Duo) for some time now. I went on a ski trip, and while using my macbook in the room, the computer froze and the graphics became distorted. A quick restart fixed it. When I got back up to school, I tried to turn my macbook on and the same grey particles were on the screen and the screenshot below is where I'd end up. Was about to get ready to go to the Mac store, tried it again and it works fine. For about a month there was no problems, and then all of a sudden last night I have the same exact problem. It just freezes out of nowhere and ends up with the same screen. Left the laptop at the screen posted below, came home a while later and now it works fine again. I want to say it's the graphics processor (8600GT) but why would it keep fixing itself? My warranty is up, so no help there. Let me know what you guys think. A PRAM reset doesn't help. Your thoughts.
