DirectX Diagnostic Tool..

  1. When I type "dxdiag" in the run box in the start menu, the tool loads half way and then a notice appears saying that DirectX has to close. When I go back to run DXDT again I get a message when it is in the middle of loading asking me if I want to bypass DirectShow, and that there was an issue with DirectShow last time I loaded DXDT. Does anyone know why this is happening, what it means, or how to fix it? Any helpful response would be appreciated greatly. :)


    -Windows Vista Home Premium (never used to have this problem with XP)

    -Nvidia 8800GTX - Driver Date = 3/2/2007 Driver Version =

    Also, I am not sure if this problem is causing or at all related to the Steam games issue I am currently having when I start my Steam games and the main menu goes black...

    What version of DirectX do you have? If it isn't the latest try downloading it. That's what I would do if it happened to me. I'm no computer guru but ya know.

    I agree

    But try a seach for Dxdiag.exe.If it appears dbl click it there.
    But 9.0c has an update that might repair it.
    But a search at will quickly find the newest download.
    Not Windows update.
    It also might be a seperate install on your Vista CD.
    You absolutely need this system device,latest version.

    I have DirectX 10, that's what it says on the VERSION column.

    I would say it's a bug in the system. See if any other Windows Vista Home Premium users have that problem as well.
