Solving System Problems 8-1

Solving System
Problems

Occasionally, you may encounter a problem with your
computer. In most cases, the problem is one that you can
solve yourself.

Your system has a built-in checking program that
automatically tests its components when you turn the
system unit power on. If there is a problem, the system
displays an error message. If this happens, follow any
instructions on the screen.

If screen messages do not help or an error message does not
appear, refer to the following information in this chapter to
determine and solve the problem:

“Finding Solutions to Common Problems”
Refer to this section to solve common minor problems.

“Using the Diagnostic Diskette”
If your system boots, use the diagnostic diskette to
determine and resolve the problem.

“Getting Help”
Refer to this section if the above listed procedures have
failed to correct the problem.

FINDING SOLUTIONS TO COMMON PROBLEMS

See the following sections to match your problem area and
view the possible causes and solutions.

When trying to solve problems, you should note what the
system was doing when the problem occurred and what you
attempted to do to correct the problem. This information is
useful if you request assistance.
