    You will need to find Xp drivers , You can do this by going to www or going to the manufactures web site for each device. Or you could go to and download there free software drivers program. The card maybe bad but it just maybe the case of the drivers. I have had this happen when switching from vista to XP. Goodluck.

    Have you been able to fix your problem? If not yet, another possible cause comes to mind. Please provide the following info so I can check

    List any Problem devices
    • Make sure devices are connected and powered on
    • Click Start->Run, enter: msinfo32. Click the + sign next to Components to expand it
    • Click Problem Devices. Anything appear?
    • If yes, click on it, Ctrl-A to select all, Ctrl-C to copy it, Ctrl-V to paste into next post
    • On the other hand, if no devices are listed, tell me so
    Generate and attach a DirectX report
    • Click Start->Run, enter dxdiag and click OK
      ===> If you’re running 32 bit Windows, dxdiag will launch on its own
      ===> If you’re running 64 bit Windows, you’ll see 64-bit DxDiag. Click it to launch the 64-bit version of dxdiag
    • Notice progress in lower left window corner
    • When done, click Save Information button and save as a text file to your Desktop
    • Attach it to your next post by clicking the Upload a File button
