Chapter 8. Solving Computer Problems

Computer problems can be caused by software, hardware, or both.
You can diagnose and solve many problems with the assistance of
the self-tests and system programs contained in Easy-Setup. If a
hardware problem is detected by the self-tests, an error message is
displayed.

The system programs can identify a problem or provide information
for the service representative. Make a note of all error codes and
give them to the service representative when you call for service. If
the system programs cannot be loaded, the troubleshooting charts
and other information will help you determine what corrective action
to take.
