C:\Windows\System32
To start the DirectX Diagnostic Tool, click???????????? ????,???????????:dxdiag??????????????? ???, ?? ???? ???OK.

The following list contains a description of each tab in theDirectX Diagnostic Tool????? ????? ?? ??????? ?? ??? ?? ..

??????

The??????tab provides system information about your computer and specifies the version of DirectX that is installed on your computer.

DirectX Files

TheDirectX Filestab lists the file name and the version number for each DirectX file that is installed on your computer, as well as the file name and the version number of many common files that are used by games that are running under DirectX.

If the DirectX Diagnostic Tool detects a problem with a DirectX file, a warning message appears in the???????? ????

Display'N'

('N' is the number of the physical display device.)

The????????tab lists your current display settings, and allows you to disable DirectDraw, Direct3D, and AGP Texture Acceleration. This tab also allows testing of DirectDraw and Direct3D. Passing these tests indicates that the DirectX Graphics runtime files are installed and operating correctly. It is not a comprehensive test of your computer's display hardware.

The????????tab also lists your device's available memory and can tell you if your video driver has passed Microsoft's Windows Hardware Quality Labs (WHQL) testing regimen by checking whether theWHQL Logo'd???? ?? ??? ??? ???????,????.

???:Dxdiag.exe cannot report memory that is in use at the time that it starts. Therefore, it is not uncommon to see less memory reported than your video card actually has.

?????

The?????tab displays your current sound settings, and enables you to test DirectSound. The?????tab can tell you if your audio driver is "Signed" - which indicates that it has passed Microsoft's Windows Hardware Quality Labs testing regimen.

The Hardware Sound Acceleration Level slider is used to correct audio glitches that might be caused by some audio drivers. Reducing the acceleration by one notch and re-testing the application is the best way to troubleshoot DirectSound audio problems. Lowering the Hardware Sound Acceleration Level from the default setting of "full acceleration" may disable advanced audio processing techniques, such as 3D spatialization from functioning.

If the DirectX Diagnostic Tool detects a problem with your sound settings, a warning message is displayed in the Notes box.

Music

TheMusictab displays your current MIDI settings, and enables you to test the DirectMusic component of DirectX.

If the DirectX Diagnostic Tool detects a problem with DirectMusic, a warning message is displayed in the Notes box.

???:DirectMusic is a new component included in DirectX 6.1.

?????

The Input tab lists the input devices connected to your computer and the input drivers installed on your computer.

If the DirectX Diagnostic Tool detects a problem with an input device or an input device driver, a warning message is displayed in the Notes box.
