Troubleshooting Tools 49
A possible expansion card failure
has occurred.
1
Determine whether a conflict exists by
removing a card (not a graphics card) and
restarting the computer. See "Cards" on
page 73.
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 "Resolving Software
and Hardware Incompatibilities" on
page 53).
4
If the problem persists, contact Dell (see
"Contacting Dell" on page 124).
Another failure has occurred.
• Ensure that the cables are properly
connected to the system board from the
hard drive, CD drive, and DVD drive (see
"Drives" on page 86).
• If there is an error message on your screen
identifying a problem with a device (such
as the floppy drive or hard drive), check the
device to ensure that it is functioning
properly.
• The operating system is attempting to boot
from a device (such as the floppy drive or
hard drive); check system setup to ensure
that the boot sequence is correct for the
devices installed on your computer (see
"System Setup" on page 113).
• If the problem persists, contact Dell (see
"Contacting Dell
" on page 124).
