How to Troubleshoot DirectX Video Problems

• Microsoft Windows 95

SUMMARY

This article describes how to troubleshoot problems related to the video components of DirectX, which include DirectDraw and Direct3D. DirectX is a suite of components that helps multimedia programs achieve higher performance by accessing hardware features directly. DirectDraw is used to directly access video adapter hardware. Direct3D is used to directly access 3D rendering features built in to many video adapters.

DirectX may be installed by programs such as a game, or you can download DirectX 5.0 as a separate component from the following Microsoft Web site:

Certification of DirectX Components

1. To determine if your DirectX drivers are certified, run the Maintenance-Mode DirectX Setup program (Dxsetup.exe).

   1. Click Start, point to Find, and then click Files Or Folders.
   
   
   
   2. Type the following line in the Named box, and then click Find Now:

      dxsetup.exe

   
   
   
   3. Double-click Dxsetup.exe.

Display Problems Due to Conflicting Versions of DirectX

1. If you are running DirectX 5.0, use the DirectX Driver Tool (Dxtool.exe) to display version information for each DirectX component.



2. If you do not have DirectX 5.0 or the DirectX Driver Tool is unavailable, check the file versions of specific files. For more information, see the following articles in the Microsoft Knowledge Base:

   Q158959 Files Installed by DirectX 1.0
   
   Q158960 Files Installed by DirectX 2.0a
   
   Q158961 Files Installed by DirectX 3.0
   
   Q173479 Files Installed by DirectX 5.0




3. If you are using DirectX 5.0, you can also use DirectX Information (Dxinfo.exe) to determine which DirectX files are installed. Dxinfo.exe is located in the Program Files\Directx\Setup folder and lists each file installed with DirectX, including the file version number, file date, and file size. This information can also be saved as a text file. If the file is not located in this folder, look for the file. To do so, follow these steps:
   
   
   1. Click Start, point to Find, and then click Files Or Folders.
   
   
   
   2. In the Named box, type the following line, and then click Find Now:

      dxinfo.exe

   
   
   
   3. Double click Dxinfo.exe.
   
   
   



4. If you have conflicting versions installed, rename any files from the older version of DirectX. To do so, follow these steps:
   
   
   1. Click Start, point to Find, and then click Files Or Folders.
   
   
   
   2. In the Named box, type the following line, and then click Find Now

      <dxdriver>

      where <dxdriver> is the name of one of the older DirectX drivers.
   
   
   
   3. Click a file, and then click Rename on the File menu.
   
   
   
   4. Type the name of the file as follows

      <dxdriver>.xxx

      where <dxdriver> is the name of the DirectX driver file.
   
   
   
   5. Repeat steps 1-2 for each older DirectX file.
   
   
   
   6. Reinstall the more recent version of DirectX.
   
   
   
   7. Test the DirectX program and verify that the problem no longer occurs.
   
   
   
   8. If the problem no longer occurs, click Start, point to Find, and then click Files Or Folders.
   
   
   
   9. In the Named box, type the following line, and then click Find Now

      <dxdriver>.xxx

      where <dxdriver> is the name of one of the renamed DirectX drivers.
   
   
   
   10. Click Delete on the File menu.
   
   
   
   11. Repeat steps I-J for each file renamed in steps C-E.
   
   
   



5. If you still experience problems, you may want to reinstall DirectX. You may receive the following error message attempting to reinstall DirectX:

   Insert Disk
   The disk labeled 'DirectDraw Drivers' is now required
   This disk is provided by your computer manufacturer.
   Click OK to continue.

   If you receive this error message, see the following article in the Microsoft Knowledge Base:

1. If you did not experience problems with an earlier version of DirectX, you may want to revert to the earlier version of the DirectX driver. To do so, follow these steps:
   
   
   1. Click Start, point to Find, and then click Files Or Folders.
   
   
   
   2. In the Named box, type the following line, and then click Find Now:

      dxsetup.exe

   
   
   
   3. Double click Dxsetup.exe.
   
   
   
   4. Click Restore Display Drivers, and then click OK.
