everything keeps crashing
I really dont know a whole lot about computers but my problem is everything keeps crashing from itunes to mail to iphoto to firefox. i dont know why this keeps happening. went to disk utility to run a repair and it says everything is fine. the other day i open up my mackbook and its like everything was reinstalled. I never did a reinstall. I still had all my photos and music but it was like it went back to the original settings. Its running really slow and i have no idea how o fix it. If someone has any advise i would appreciate it.
