Under Search Criteria, select the appropriate categories from the System Model, Operating System, and Topic drop-down menus. A link or links appear(s) for the specific drivers and utilities used by your computer. 6. Click the link of a specific driver or utility to display information about the driver or utility that you want to install. 7. Click the Install button (if present) to begin installing the driver or utility. At the welcome screen, follow the screen prompts to complete the installation.
