Memory modules are detected,
but a memory failure has
occurred. • 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,
remove the modules, reinstall
one module, and then restart
the computer. If the
computer starts normally,
reinstall an additional
module. Continue 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.
• If the problem persists,
contact Dell.
A possible graphics card failure
has occurred. • 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
information on contacting
Dell, see your online
User’s
