So I have panther on my 12" 867 pb with superdrive, a few months ago i started getting random lockups and I was forced to restart my computer, so about a month ago I did a clean reinstall and ran 10.3.1 because I thought 10.3.2 was the problem, low and behold it was not the problem because the same issue persisted. At night I used to like to leave my laptop in screensaver mode/ screen off with my away message up and now every time I do that over night I come back and the computer is frozen and i have to shut down via the power button and restart. Any ideas on what this is. I repaired permissions about two weeks ago after installing iLife and have had any big installs since.
