Well, not crashed, but overheated it. First time that's ever happened on the Macbook Pro. I was trying to run the stabilization process on my movies, had been running it for some 2 days now and was about 20-25% complete, when all of a sudden the screen started getting flaky, programs started slowing down, and eventually the external display died and the computer slowly started seizing up. Rebooted and everything is fine now, but let that be a lesson to you: iMovie's Image Stabilization is extremely intensive. My processor was running at 101 Celcius for a while... I think I'm going to be more conservative with my stabilization, and give the poor computer a chance to breathe every now and again.
