It started when my Powerbook G4 starting acting strange. Firefox, Rapid Weaver, Safari, and Flock all kept crashing and i would get kernel panics. I brought it to the Genius Bar and they guy told me that there was nothing physically wrong with the HD, but I needed to do an erase and install. I tried that but when i did i got an error. I tried it again and same thing. Now I am stuck with a PBook with no OS. Any suggestions
