Problem Cause Solution
A new device is not recognized as
part of the system.
Device is not seated or
connected properly.
Be sure that the device is properly and securely connected
and that pins in the connector are not bent.
Cables of new external device
are loose or power cables are
unplugged.
Be sure that all cables are properly and securely connected
and that pins in the cable or connector are not bent.

A PNP board might not
automatically configure when
added if the default
configuration conflicts with
other devices.
Use the Device Manager to clear the automatic settings for
the board and select a basic configuration that does not
cause a resource conflict. You can also use Computer
Setup to reconfigure or disable devices to resolve the
resource conflict.
Device hardware is not
properly jumpered or
otherwise configured.
Read the device-specific configuration information and
check for incorrect settings or conflicts with other devices
already installed in the system.
Workstation will not start. Wrong memory modules were
used in the upgrade or memory
