A possible graphics card failure
has occurred.
Suggested Resolution
• If you have one memory
module installed, reinstall it
and restart the computer (see
the online User's Guide for
instructions on how to
remove and install memory
modules).
• If you have two or more
memory modules installed,

have identified a faulty
module or reinstalled all
modules without error.
• If available, install properly
working memory of the same
type into your computer.
• If the problem persists,
contact Dell.
• If the computer has a
graphics card, remove the
card, 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 or the
computer has integrated
graphics, contact Dell for
technical assistance. For
