Light Pattern Problem Description
A possible expansion
card failure has
occurred.
Another failure has
occurred.
Suggested Resolution
1
Determine if a conflict exists by
removing an expansion card (not a
graphics card) and restarting the
computer (see "Cards" on page 162).
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 "Restoring Your
Operating System" on page 136).
4
If the problem persists, contact Dell
(see "Contacting Dell" on page 269).
• Ensure that all hard drive and
CD/DVD drive cables are properly
connected to the system board (see
"System Board Components" on
page 148).
• 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 CD/DVD drive), check
system setup (see "System Setup" on
page 81) 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 269).
