Incompatible Software
---------------------
Many pieces of software (System, INITs, Applications) are loaded into
memory and run at the same time. System bombs occur if the versions of the
software aren't compatible. You may call the application's manufacturer to
find out if the software is compatible with your system and the other
software you are running. You can find versions of programs, INITs, and
the System file by selecting the file's icon at the Finder and choosing Get
Info from the File menu.
Corrupt Software
----------------
Sometimes a piece of software may become corrupted. Events that can
corrupt files include:
- Not choosing Shut Down before turning off your Macintosh.
- SCSI data line problems can corrupt software or even the format of your
hard disk.
Viruses
-------
A virus is seldom destructive, but can do any of the following:
- Display messages.
- Corrupt software.
- Change software or hardware settings.
- Cause system bombs.
The Tech Info Library contains several articles about viruses and their
symptoms.
Hardware Problems
-----------------
In a few cases, certain hardware problems may cause system bombs. Using
peripherals or expansion cards that aren't fully compatible with the
computer can cause bombs. Bad or insufficient memory may also cause bombs.
