Solving Problems

Your system has a built-in checking program that automati-
cally 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, use the information in this chapter to determine and
solve the problem. The problem is often one that you can
solve yourself.

PROBLEM CHECKLIST

First check the items in the following list. If these do not
help, see the table that follows the list. If you still cannot
determine the problem, see "If You Need Assistance" in
this chapter.
Check that the following conditions are true for your
computer:
The power switch for each component is on.
All cables and power cords are tightly connected.
The electrical outlet to which your components are con-
nected is working. Test the outlet by plugging in a lamp
or other electrical device.
The monitor's brightness and contrast controls are
adjusted properly.
All option boards in the expansion slots are seated
securely in their connectors.
