Apple Power Macintosh 9600 - Manual (Page 140)

The computer “freezes.”
m Your computer may be trying to complete a task, but it’s taking so long that
it seems that the screen has frozen. If you need to do something else
instead, try simultaneously pressing the Command (x) key and the period
key (.) to cancel the task the computer is working on.
m There may be a temporary software problem that can be fixed by restarting
your computer. Follow the instructions in “Step 2: Restart Your
Computer” in Chapter 9, “Start Here If Trouble Occurs.”
If the problem reoccurs, it may involve one or more of your application
programs. See the next entry for additional suggestions.
A dialog box with a bomb appears, or a dialog box indicates that a software application
program has quit unexpectedly.
The application program needs more memory, or there is a software problem.
m Write down what you were doing when the message appeared, and write
down the text of the message. This information may help a technical
support representative diagnose your problem if you later need to contact
Apple or the manufacturer of the application program.
About the codes in error messages: The number codes in error messages are
used in software development. Sometimes they can help a technician
narrow down the source of a problem. However, the codes are usually too
general or technical in nature to help you diagnose a problem yourself.
