  • Hi

     

    When you uninstalled the nVidia driver, it sounds like it did not remove the reference to that tray component that is set to start when you turn the computer on.

     

    Go to Start and type   msconfig   in the Search Box. Press Enter.

     

    This will open the Configuration Editor. Select the Startup Tab.

     

    Look for an entry there that refers to that  NvMc Tray.dll file.

     

    Remove the check mark from that entry.

     

    Reboot the computer to see if the error message returns.

     

    Let us know the results.

    What did you find when you opened  msconfig ???

     

    Here are a couple of items that you may see in the msconfig/Startup tab.

     

    RUNDLL32.EXE C:\WINDOWS\System32\NvCpl.dll,NvStartup
    RUNDLL32.EXE C:\WINDOWS\System32\NVMCTRAY.DLL,NvTaskbarInit

     

    Remove the check mark from all of these.

     

    Make sure you click Apply/OK, after you remove the check marks.

     

    Reboot the computer.

     

    Another way to accomplish this is to edit the registry.

     

    Go to Start and type  regedit.exe  in the Search Box. Press Enter.

     

    Approve the UAC prompt.

     

    In the registry, there are 3 locations that will cause this item to be added to the msconfig startup list.

     

    Navigate to each of the following locations.

     

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

     

    In each location, click the 'Run' key and look in the right side of the window.

     

    If you see any value there that shows either of these commands:

     

    RUNDLL32.EXE C:\WINDOWS\System32\NvCpl.dll,NvStartup
    RUNDLL32.EXE C:\WINDOWS\System32\NVMCTRAY.DLL,NvTaskbarInit

     

    Right click the value and select Delete.

     

    Exit the registry editor.

     

    Let us know the results.
