I have a 12 inch powerbook g4 1.33mhz and for the first time, since i purchased this laptop, its been acting up on me. Every program closes unexpectedly. Safari acting the worst, after 2 minutes of surfing it constantly closes. I've tried repairing the permissions on my laptop, but that seemed to prove useless. I've created another account, and this problem persists on that account as well. Here is a list of programs that I have used and closed unexpectedly: Mail, Firefox, Safari, Iphoto, itunes, ical, AIM and some others. Can anyone help me out and tell me what the problem could be? How can I fix it? I am hoping I dont have to restore my hard drive if i dont have to.
