Advanced Troubleshooting

A possible expansion card failure has occurred. 1 Determine whether a conflict exists by
removing a card and restarting the computer
(see page 66).
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 page 49).
4 If the problem persists, contact Dell (see
page 102).
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 61).
• 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 (see page 91)
to make sure the boot sequence is correct for
the devices installed on your computer.
• If the problem persists, contact Dell (see
page 102).
During normal operation, all of the diagnostic
lights turn on and then turn off before the
system starts.
NOTE:
If all of the diagnostic lights are on and
the system does not start, there may be a
problem with the power supply or with the
processor.
If the system does not start, plug the
computer into a working electrical outlet. Also
see "Power Problems" on page 36.
If there are no power problems and the system
does not start, contact Dell (see page 102).
