My PowerBook G4 15in 1.25GHz has been having a bunch of issues sadly. The issue is that it keeps freezing at random, most of the time without a KP. I've swapped the RAM multiple times to known working sticks, formatted the drive and reinstalled Leopard and Tiger, did a PMU reset, opened it up and unplugged everything and plugged it back in, and lastly I did a PRAM reset (which seems to help for a little while longer than normal). The only diagnostic task i haven't done is try another HDD. Anyone have any ideas? I really like this machine... It's the perfect size! (although I'm typing this from my 17in, which feels really nice ) Also, happy thanksgiving to all the US people here!
