Guest beemer Posted September 25, 2008 Posted September 25, 2008 A problem that I share with others is that the Nvidia Control panel fails to open. This was cured when I did a registry fix to enable an older "Classic Control Panel". After a second try to open the Classic version it too will not open. I now cannot change the brightness or contrast of either of my two displays as the control panel when it was working adjusted the levels beyond the display's own manual adjustment. Despite uninstalling, cleaning out old drivers and reinstalling the driver (new and old) I cannot get the Nvidia control panel to open. This is why I am wanting to know if I can "reset" the NVidia to its default through the XP registry? Hope someone can help. regards, Beemer
Guest ju.c Posted September 25, 2008 Posted September 25, 2008 Re: Does the XP registry hold Nvidia video card settings? Hopefully something here will work. Try registering these files: Open the Run box and, one at a time, enter: regsvr32 C:\WINDOWS\system32\nvcpl.dll regsvr32 C:\WINDOWS\system32\nvcpl.cpl See if you can open the nVidia Control Panel manually. Open the Run box and enter: %SystemRoot%\system32\nvcplui.exe Are you sure you've got the latest driver? There is a link here to do an automatic scan: http://www.nvidia.com/Download/index.aspx?lang=en-us These keys and their subkeys hold the settings: [HKEY_CURRENT_USER\Software\NVIDIA Corporation\Global\nView] [HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak\Defaults\Overlay] ju.c "beemer" <beemer@nowhere.com> wrote in message news:uNnK#CvHJHA.1160@TK2MSFTNGP05.phx.gbl... > A problem that I share with others is that the Nvidia Control panel fails to > open.

That just eliminates one possibility. > "DllRegisterServer in C:\windows\system32\nvcpl.dll failed. Return code was: 0x80070005 That's a problem. Usually it is recomended to uninstall nVidia, reboot and install the latest version. (Because it is easier than trying to figure out what the actual problem is) But since you said you already did that you're going to find it hard to solve this problem. Keep looking. Did this work? See if you can open the nVidia Control Panel manually.
