A possible graphics card failure has occurred. A possible floppy or hard drive failure has occurred. If you have one memory module installed, reinstall it (see page 57) and restart the computer. If you have two or more memory modules installed, remove the modules, reinstall one module (see page 57), 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 57). If the problem persists, contact Dell (see page 105). If the computer has a graphics card, remove the card, reinstall it (see page 60), 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 (see page 105). Reseat all power and data cables and restart the computer. A possible USB failure has occurred. Reinstall all USB devices, check cable connections, and then restart the computer.
Light Pattern Problem Description Suggested Resolution A B C D A B C D = yellow = green = off Memory modules are detected, but a memory configuration or compatibility error exists. A possible expansion card failure has occurred. Ensure that no special memory module/memory connector placement requirements exist (see page 57). Verify that the memory modules that you are installing are compatible with your computer (see page 57). If the problem persists, contact Dell (see page 105). 1 Determine if a conflict exists by removing a card (not a graphics card) and restarting the computer (see page 60). 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 46). 4 If the problem persists, contact Dell (see page 105).
