Just to add another frustrating detail to the problem: earlier I turned it on, let it boot, and did NOTHING - just let Finder sit there. It must've been on for 10 minutes before I realized that the screensaver hadn't even started...move the trackpad, NOTHING. So here we have a computer that boots nothing but the operating system freezing consistently. I wanted to isolate a program installed that would cause the system's instability, but this adds a whole new dimension to the problem...it's freezing for no reason, with no intervention. -------------- next part -------------- An HTML attachment was scrubbed...
