Reinstalling Drivers and Utilities
NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities CD provide approved drivers for
Dell™ computers. If you install drivers obtained from other sources, your computer might not work correctly.
NOTE: The Drivers and Utilities CD (ResourceCD) is optional, and as such, may not ship with all computers.

the driver with the previously installed version.
