Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove
hardware, such as an additional drive or expansion card. If you install
a plug and play device, Windows XP Home/Professional/Vista will
automatically recognize the device and configure the computer. If
you install a nonplug and play device, you must reconfigure the
computer after completing installation of the new hardware. In
Windows XP Home/Professional/Vista, use the
Add Hardware
Wizard
and follow the instructions that appear on the screen.
Problem

recognized as part of the
system.
Cause
Device is not seated or
connected properly.
Cable(s) of new external
device are loose or power
cables are unplugged.
Power switch of new
external device is not turned
on.
When the system advised
you of changes to the
configuration, you did not
accept them.
A plug and play board may
not automatically configure

other devices.
Solution
Ensure that the device is
properly and securely
connected and that pins in

Turn off the computer, turn

Reboot the computer and
follow the instructions for
accepting the changes.
Use Windows XP Device
