Power Light Problem Description Suggested Resolution Memory modules are detected, but a memory configuration or compatibility error has occurred. • Ensure that no special requirements for memory module/connector placement exist (see "Memory" in the User's Guide). • Ensure that the memory you are using is supported by your computer (see the specifications for your system). • If the problem persists, contact Dell (see "Contacting Dell" in the User's Guide). A possible expansion card failure has occurred. 1 Determine if a conflict exists by removing an expansion card (not a graphics card) and restarting the computer (see the "Cards" section for your system). 2 If the problem persists, reinstall the card you removed, then remove a different card and restart the computer. 3 Repeat this process for each expansion card installed. If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts (see "Resolving Software and Hardware Incompatibilities" on page 72). 4 If the problem persists, contact Dell (see "Contacting Dell" in the User's Guide).
