How to get out of lock-ups or freezes?
Many computer lock ups are caused by memory over load or by one particular program freezing. The best thing you can do when you suspect your computer is locked up is hold down the Apple, Option keys and hit the Esc button. This will bring up a window that says Force Quit and it will list the program that is currently frozen. It may let you Force Quit that program and sometimes not. Either way after this procedure you should also restart your computer. Another trick that comes in handy if you don’t know how to get out of a program, especially happens with games, is to use the Apple key and the Q key to Quit an application.
