A possible floppy or hard drive failure

has occurred.

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.

No memory modules are detected.

• Reinstall all memory modules (see

page 64) and restart the computer.

• To eliminate the possibility of a

faulty memory connector, remove

all memory modules, reinstall one

memory module (if the computer

supports a single module) (see

page 64), and then restart the

computer. If the computer starts

normally, move the memory module

to a different connector and restart

the computer. Continue until you

have identified a faulty connector or

reinstalled all modules without

error.

Memory modules are detected, but a

memory configuration or

compatibility error exists.

• Ensure that no special memory

module/memory connector

placement requirements (see

page 64) exist.

• Verify that the memory modules

that you are installing are

compatible with your computer (see

page 70).

• If the problem persists, contact Dell

(see page 78).
