What older driver worked for you? You can find this ino here. From within Windows, click on the Start button -> Settings -> Control Panel. This will bring up the Control Panel. Double click on the Display icon. This will open up your display properties. Inside the display properties, click on Settings -> Advanced, and then click on the tab with the name of the NVIDIA graphics card installed in your PC. On the bottom of this tab, you will see a white box listing the driver files followed by the driver version. They should all display the same number. The last four digits represent the driver version (ex: 4.13.01.2183 means the driver version is 21.83).
