A possible graphics card failure has occurred. • If the computer has a graphics card, remove
the card (see "Removing PCI and PCI
Express Cards" on page 89), reinstall it, and
then restart the computer.
• If the problem still exists, install a graphics
card that you know works and restart the
computer.
• If the problem persists, contact Dell (see
"Contacting Dell" on page 142).
A possible floppy drive or hard drive failure has
occurred. Reseat all power and data cables and restart

installed, remove the modules, reinstall one
module (see "Installing Memory" on

the computer starts normally, reinstall an
additional module. Continue until you have
identified a faulty module or reinstalled all
modules without error.

"Installing Memory" on page 80).

"Contacting Dell" on page 142).

installing are compatible with your computer
(see "Memory" on page 79).
