Problem Description
A possible expansion card failure has occurred.
Another failure has occurred.
Suggested Resolution
Determine if a conflict exists by removing an
1
expansion card (not a graphics card) and
restarting the computer (see the "Cards"
section for your computer).
If the problem persists, reinstall the card you
2
removed, then remove a different card and
restart the computer.
Repeat this process for each expansion card
3
installed. 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
and Microsoft Windows Vista
Systems" on page 358).
If the problem persists, contact Dell (see
4
"Contacting Dell" on page 370).
• Ensure that all hard drive and optical drive
cables are properly connected to the system
board (see the "System Board Components"
section for your computer).
• If there is an error message on the screen
identifying a problem with a device (such as
the floppy drive or hard drive), check the
device to make sure it is functioning properly.
• If the operating system is attempting to boot
from a device (such as the floppy drive or
optical drive), check system setup (see
"System Setup" on page 280) to ensure the
boot sequence is correct for the devices
installed on your computer.
• If the problem persists, contact Dell (see
"Contacting Dell" on page 370).
