Follow this procedure to troubleshoot resource and device conflicts.

NOTES:

• Install any original or updated device drivers available online.
• Some devices may not be seen or easily removed without starting the computer in Safe Mode .
• Because each of these steps represents a possible solution to this problem, check the device status in Device Manager after completing each step.

1. Restart the computer.
2. Remove any conflicting or disabled devices  from Device Manager.
3. Reset the computer BIOS to the default values.  
4. Ensure any added hardware device is properly connected.
5. Remove all third-party hardware.

   NOTE: If removing third-party hardware resolves the issue, contact the third-party manufacturer for additional help installing the hardware without conflicts.

6. Restore the computer to a previous working configuration using the System Restore feature.

If the issue is still unresolved, service may be required.
