A possible failure has been 

detected in a plug-in 

component such as a graphics 

riser card or memory 

riser card.

Verify that any required power cables are 

connected to the memory and graphics 

riser cards.

A possible power supply 

failure has occurred.

Verify that both power supply cables are 

plugged in to the motherboard.

A possible processor failure has 

occurred.

Reinstall the processor and restart the computer.

A possible expansion card failure 

has occurred.

Determine if a conflict exists by removing a card (not the 

graphics card) and then restarting the computer.

If the problem persists, reinstall the card that you 

removed, remove a different card, and then restart the 

computer.

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 32).

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.

A possible floppy or hard drive 

failure has occurred.

Reseat all power and data cables and restart the computer.
