Problem Description A possible expansion card failure has occurred.
Troubleshooting
Steps
• Determine if a conflict exists by removing an
expansion card (not a graphics card) and restarting
the computer.
• If the problem persists, reinstall the card you
removed, then remove a different card and restart
the computer.
• Repeat this process for each expansion card
installed. If the computer starts normally,
troubleshoot the last card removed from the
computer for resource conflicts.
