Advanced Troubleshooting 35
A possible expansion card failure has
occurred.
1
Determine if a conflict exists by
removing a card (not a graphics card)
and restarting the computer (see
page 56).
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 44).
4
If the problem persists, contact Dell
(see page 89).
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 page 53).
• 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 make
sure 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 (see page 80) to make sure that
the boot sequence is correct for the
devices installed on your computer.
• If the problem persists, contact Dell
(see page 89).
