www.dell.com | support.dell.com Light Pattern ABCD ABCD ABCD = yellow = green = off Problem Description Memory modules are detected, but a memory failure has occurred. A possible expansion card failure has occurred. Suggested Resolution • If you have one memory module installed, reinstall it (see page 64) and restart the computer. • If you have two or more memory modules installed, remove the modules, reinstall one module (see page 64), 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 (see page 64). • If the problem persists, contact Dell (see page 78). 1 Determine if a conflict exists by removing a card (not the video card) (see page 51) and then restarting the computer. 2 If the problem persists, reinstall the card that you removed, remove a different card, and then restart the computer. 3 Repeat this process for each card. If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts (see "Resolving Software and Hardware Incompatibilities" on page 44). 4 If the problem persists, contact Dell (see page 78). 36 Advanced Troubleshooting
