Solving Computer Problems
Problems with your computer can be caused by software, hardware,
or both. You can test the hardware yourself using computer internal
self-tests and the testing programs on the backup copy of the
Reference Diskette. If a hardware problem occurs during this testing,
an error message appears with the cause of the problem and the
action to take.
By using the Reference Diskette, the Troubleshooting Charts, and
the other information in this section, you should be able to solve the
problem yourself or obtain a considerable amount of information
about the problem.
Always use the backup copy of the Reference Diskette. The backup
copy should contain your computer's current configuration
information and testing programs.
