7-4 Solving Problems
Troubleshooting
PROBLEM CORRECTIVE ACTION
There is constant movement
on the screen.
A magnetic field is affecting your monitor. If
you have another monitor nearby, or other
device with a motor that generates a
magnetic field (for example, a fan), move
the monitor or device away from the
affected monitor.
Your screen display is fuzzy or
graphics characters or “garbage”
appear on the screen.
Check that your monitor is set up correctly.
Check the monitor connections. Make sure
that the monitor signal connector pins
are not damaged. Be sure that the correct
video driver is installed.
Keyboard/Mouse Problems
An image appears on the screen
but nothing happens when you
use the keyboard or mouse.
Check and tighten the keyboard or mouse
cable connection. If this doesn't help, power
off the system. Wait 5 seconds and power
on the system.
Performance Problems
System performance appears
sluggish.
Check that you have your system set for
optimal operation. See your Microsoft
Windows for Workgroups and MS-DOS
documentation.
Check the memory requirements of your
software applications. If required, install
additional memory (see “SIMM Upgrade
Kits” in Chapter 5).
If you added optional memory, check that
you installed the SIMM sticks correctly (see
“SIMM Upgrade Kits” in Chapter 5).
