The ATI SB450 high-definition audio controller comes on a number of medium- to high-end motherboards. The chipset is also used with some third-party devices to provide high-definition audio. In the past, installing a driver meant locating the device's software and using the Device Manager to install the software manually. Now, Microsoft Windows 7 is able to download drivers from a Microsoft database that contains only the most recent software for your device.

Skill level:


  1. 1

    Click the "Start" button, then click the "Devices and Printers" icon. Right-click your computer in the list, then click the "Device installation settings." Click the "Yes, do this automatically" option box, then click the "Save Settings" button to exit.

  2. 2

    Click the "Start" menu, then type "Update" into the Search box. Click the "Windows Update" option in the list, then click the "Check for Updates" button in the left portion of the dialogue.

  3. 3

    Select the ATI SB450 option from the list, then click the "OK" button. Click the "Install Updates" button to download and install the necessary drivers for your device.
