I am using iBook G4 laptop and I have 512 MB RAM and ATI Mobility Radeon 9550 graphics. I have Mac OS X 10.4 in my laptop. My laptop was working like a charm and it has suddenly started giving me problems. Now when I use Safari browser at that time it crashes. I have tried to find reason forth is issue and after spending some hours I have come to know that java is causing this problem. If I disable java then safari browse works fine but websites does not load properly with java disabled. Please tell me what should I do to solve this problem?
