On the site you go to the drivers section to find the latest driver you could use for your card. To do this you will need your graphics card's type ID code, which you can find as follows:
Right click your My computer icon
Go to the hardware tab
Click device manager
In the new list that appears select "Display Adapters"
Double click on your graphics adapter and a new window will appear
Select the details tab
Make sure the drop down has "Device Instance Id" selected.
The list underneath will display your device information (It looks like PCI\VEN_ etc...)
You can enter this code on the website to find your latest driver.
When I tried the latest driver, the setup did not recognize my card, so I had to get the update INF file as well from the site.
Now my laptop thinks I have a GeForce card but I can live with that... game on!
Hope this helps others with similar NVIDIA problems.
