Guide for Updating Video Card Drivers From Nvidia
1. Go to
http://www.nvidia.com and download the notebook specific driver for your version of windows and your video card (either 9400 or 9600).
2. From the Start Menu in Windows, go to run and type dxdiag. Once the window appears, on bottom right hand side there is an option to "Save All Information". Save this information on your Desktop. It will save a .txt file to your desktop.
3. Within this text, file search for "Device Key". You only need to use a certain piece of the Device and Subsystem ID such as "DEV_0863&SUBSYS_00B9106B&REV_B1" from my base MacBook Pro 13. This will be important in the next step.
4. Now you will need a tool like WinRar to extract the files from the Nvidia driver executable. Once you have WinRar or similar installed, you can right on the Nvidia driver executable and choose extract.
5. Within the file folder extracted from the Nvidia driver executable, you will need to open the file nvam.inf with notepad or another text editor. Once the file opens, scroll to the bottom of the file and you should begin to see text such as "NVIDIA_DEV.0862.01 = "NVIDIA GeForce 9400M G"".
Find the first line associated with your video (either 9600GT or 9400M). Now copy the number following NVIDIA_DEV. such as "0862". Now you will need the Device and Subsystem ID found earlier in Step 3.
6. Return to the top of the nvam.inf file, and from your text editor's menu, choose find and enter the number found in Step 5 such as "0862". There are two instances to find. Once you have found the first, towards the end of the line you should see the text "PCI\VEN_10DE&", highlight all the text following this and paste the Device and Subsystem ID found earlier in Step 3. You should end up with something like "%NVIDIA_DEV.0862.01 = Section52, PCI\VEN_10DE&DEV_0863&SUBSYS_00B9106B&REV_B1".
Make sure to do this for both instances.
7. Now you must uninstall the nvidia display driver from the control panel. Make sure to only uninstall the display driver as that is all you are updating (my MacBook Pro had four drivers associated with the Nvidia uninstaller).
8. Now you can reboot. Once your computer has restarted, within the file folder extracted from the Nvidia driver executable, you can simply double click the setup.exe, and your new driver will install.
