MBP Details: 2010 Model, Refurb. 2.4Gz i5 CPU 4GB DDR3 Ram Mac OS X 10.6.7 Hi all, this is my first post here, and I've been having severe problems with my MBP recently. For the past month maybe, it's been crashing more and more often. Now, it seems to crash almost every time I move it from my lap to the coffee table, and even then it randomly does so while I'm using it. I'm never running much more than Chrome and Photoshop/Illustrator and a few menubar addons. The screen freezes, nothing moves and I'm forced to hold the power button until it restarts. Often, if I restart too soon, even gently tapping the machine will cause the screen to tear into a multicoloured rainbow. Any clues as to what might be up? Here's the latest crash report: NOTE: I desperately needed the machine recently but I'll be finishing college soon for the summer and will be able to send it off as it's still under warranty.
