Apple Power Macintosh 7200 - Manual (Page 80)

A dialog box with a bomb appears.
Your system has a software problem.
m Write down what you were doing when the message appeared and write
down the message’s text and its number, if there is one.
m Restart your Macintosh. (See “Start Over” in the section “If You Have
Trouble” earlier in this chapter for instructions.) Most software problems
are temporary, and restarting usually corrects the problem.
m Check the startup disk and application program you were using when the
dialog box appeared. Make sure that all programs, desk accessories, and
system extensions you’re using are compatible with the system software.
Reinstalling the system software may correct the problem.
m If the bomb only occurs in one application program, try reinstalling the
program from the original disks. If reinstalling doesn’t solve the problem,
contact the manufacturer of the program.
m Sometimes incompatible system extensions or control panels can cause
system software problems. Restart while holding down the Shift key to
temporarily turn off all system extensions.
If your computer works normally after you do this, restart your computer
again. Then use the Extensions Manager control panel to turn off
individual extensions and control panels. For detailed instructions, see the
“Customizing Your Computer” or “Setting Options” topic of Macintosh
Guide, available in the Guide (h) menu.
If your computer performs better when a particular extension or control
panel is turned off, contact the extension’s or control panel’s manufacturer
for information or an upgrade.
m If the problem recurs, you may need to reinstall system software. See
“Installing or Reinstalling System Software” later in this chapter for
instructions.
