Light Pattern | Problem Description | Suggested Resolution |
A possible expansion card failure has occurred.
1 Determine if a conflict exists by removing a card (not the graphics card) and then restarting the computer (see "Cards" on page 193).
2 If the problem persists, reinstall the card that you removed, remove a different card, and then restart the computer.
3 Repeat this process for each card. If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts (see "Troubleshooting Software and Hardware Problems in the Microsoft® Windows® XP and Microsoft Windows Vista™ Operating Systems" on page 143).
4 If the problem persists, contact Dell for technical assistance (see "Contacting Dell" on page 295).
