Suggested Resolution

 

 

 

 

 

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 "Removing PCI

 

 

 

and PCI Express Cards" on page 95).

 

 

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

 

 

 

"Troubleshooting Software and Hardware

 

 

 

Problems" on page 83).

 

 

4

If the problem persists, contact Dell (see

 

 

 

"Contacting Dell" on page 179).

 

 

 

 

Another failure has occurred.

• Ensure that all hard drive and optical drive

 

 

 

cables are properly connected to the system

 

 

 

board (see "System Board Components" on

 

 

 

page 89).

• If there is an error message on the screen identifying a problem with a device (such as the floppy drive or hard drive), check the device to make sure it is functioning properly.

• If the operating system is attempting to boot from a device (such as the floppy drive or optical drive), check system setup (see "System Setup" on page 166) to ensure the boot sequence is correct for the devices installed on your computer.

• If the problem persists, contact Dell (see "Contacting Dell" on page 179).
