A possible expansion card failure has occurred. 1
Determine if a conflict exists by removing an
expansion card (not a graphics card) and
restarting the computer (see "Removing PCI
and PCI Express Cards" on page 95).
2
If the problem persists, reinstall the card you
removed, then remove a different card and
restart the computer.
3
Repeat this process for each expansion card
installed. If the computer starts normally,
troubleshoot the last card removed from the
computer for resource conflicts (see
"Troubleshooting Software and Hardware
Problems" on page 83).
4
If the problem persists, contact Dell (see
"Contacting Dell
" on page 179).
Another failure has occurred.
• Ensure that all hard drive and optical drive
cables are properly connected to the system
board (see "System Board Components" on
page 89).
• 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 166) 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 179).
