It does not seem to matter what I am doing it will freeze up after just a few key strokes. I have to force quit by holding down the start button. When I turn it back on it takes even fewer key strokes for it to freeze up. Basically, I can not use it like this. It worked fine until this happened. The first time it happened I did not know how to force quit. I tried unplugging and then I tried taking the battery out(neither worked). I then used another computer and discovered how to force quit. Any help will be appreciated.
