Problem Description
A possible graphics card failure has
occurred.
A possible floppy drive or hard drive
failure has occurred.
A possible USB failure has occurred.
No memory modules are detected.
Memory modules are detected, but a
memory configuration or compatibility
error has occurred.
Suggested Resolution
• Reseat any installed graphics cards (see
"Cards" on page 70).
• If available, install a working graphics
card into your computer.
• If the problem persists or the computer
has integrated graphics, contact Dell
(see "Contacting Dell" on page 112).
Reseat all power and data cables.
Reinstall all USB devices and check all
cable connections.
• If two or more memory modules are
installed, remove the modules (see
"Removing Memory" on page 70), then
reinstall one module (see "Installing
Memory" on page 68) and restart the
computer. If the computer starts
normally, continue to install additional
memory modules (one at a time) until
you have identified a faulty module or
reinstalled all modules without error.
• If available, install properly working
memory of the same type into your
computer (see "Installing Memory" on
page 68).
• If the problem persists, contact Dell
(see "Contacting Dell" on page 112).
• Ensure that no special requirements
for memory module/connector
placement exist (see "Memory" on
page 66).
• Ensure that the memory you are using
is supported by your computer (see
"Memory" on page 66).
• If the problem persists, contact Dell
(see "Contacting Dell" on page 112).
