Advanced Troubleshooting 41
A possible video card failure has
occurred.
• If the computer has a video card,
remove the card and reinstall it
(see page 62), and restart the
computer.
• If the problem still exists, install
a video card that you know works
and restart the computer.
• If the problem persists or the
computer has integrated video,
contact Dell (see page 90).
A possible floppy or hard drive failure
has occurred.
Reseat all power and data cables
and restart the computer.
A possible USB failure has occurred. Reinstall all USB devices, check
cable connections, and then restart
the computer.
No memory modules are detected.
• Reinstall all memory modules
(see page 75) and restart the
computer.
• To eliminate the possibility of a
faulty memory connector, remove
all memory modules (see
page 75), reinstall one memory
module (if the computer
supports a single module), and
then restart the computer. If the
computer starts normally, move
the memory module to a
different connector and restart
the computer. Continue until
you have identified a faulty
connector or reinstalled all
modules without error.
