A possible PCI expansion card failure
has occurred. • Determine if a conflict exists by removing a card (not the
video card) and then restarting the computer.
• If the problem persists, reinstall the card that you
removed, remove a different card, and then restart the
computer.
• Repeat this process for each card. If the computer starts
normally, troubleshoot the last card removed from the
computer for resource conflicts (see ""Resolving Software
and Hardware Incompatibilities" on page 24").

restart the computer after each move.
