GarageBand does not open (says its missing Quicktime content), Firefox freezes and crashes every 5-10 minutes and keyboard and trackpad do not work from time to time (not responsive at all sometimes).
What should I do?
I have stock RAM but I have a lot of third pary apps like Google Earth, HoltPuzzle Pro, Logger Pro 3, Macromedia Suit, Marble Blast Gold, Stuffit Expander and USB Shot.
