I was somewhat distraught recently because my 12-inch powerbook had the penchant for crashing with more regularity than I would like. (I am defining crash as the window popping up telling me in several languages that something very bad has happened and I must hard-restart the machine.) Doesn't matter if I'm word processing, internetting, DVD-watching or nothing is running except OSX. Well, I figure out out what it is. If I try to pick up the machine from the front-left (as I look at it) quadrant, it crashes. Everytime. Conversely, it never crashes at other times. I guess I'm pinching the hard drive or something. Would that cause the crash? Any techies know? Anybody else have this experience?
