Go to Lenovo's support site, install the system update utility from there, run it. It will find and install the latest drivers for your system. If you tried to get the video drivers directly from nVidia, that won't work properly for the laptop, you need to use the Lenovo drivers.
If your card does not have the correct specs to run the program, you will need to get a new laptop, you can't just add more dedicated memory to a video card through drivers, the memory is physiclaly on the board.
