Hey, I recently inherited a 15" PB 1.5ghz from a coworker running OS 10.3.9. When I received it, it was freezing up all the time (no mouse movement, no commands accepted, only forced reboots worked.) I promptly bought Tiger, zero'd the HDD and installed. The computer ran fine for the first day or so, then began freezing again, once or twice a day. Yesterday, it began kernel panicing as well, so I called AppleCare and went through a day and a half of phone conversations and emails to get a tech tell me to reset the PMU, NVRAM, and PRAM and use the computer in safe boot for several hours to see if it still crashed. Well, it didn't crash in the hour I had it in safe mode, but after that I had to actually get work done and booted back into the regular OS. Worked fine for a couple of hours, then got an odd freeze where several lines of white text on black showed up onscreen. Forced a shutdown, then used it again for several hours, but when I went to set it down for a moment, I shook it a bit and it froze again. This feels alot like HDD failure to me, but I was wondering what the more experienced Mac users thought.
