How to Find DXDiag on Vista

Programs created with DirectX require a specific level of hardware and drivers in order to function properly. When troubleshooting problems with your hardware or running DirectX-related software, use the DirectX Diagnostic Utility, or DXDiag, to confirm the specifications and drivers for all of your hardware and to identify any problems they may have.
