On some configurations, DirectX« Diagnostic Tool allows you to restore older audio and video drivers. This may be the best way of solving problems with incompatible drivers.
If a Restore button appears on the More Help page, click this button to run the DirectX Setup program.
DirectX Setup has two buttons labeled Restore Audio Drivers and Restore Display Drivers. Clicking either of these buttons restores drivers that were replaced when DirectX was installed on your system. If a button is disabled, you do not have older drivers to switch back to. In that case, contact the hardware manufacturer for the newest drivers.
DirectX Setup also provides a checkbox to disable Direct3D hardware acceleration, which is something you can already do from within DxDiag. (See Overriding Default Behavior.)
