So many of you have asked how to update drivers in Windows Xp/Visa/7. YOu all probably noticed that drivers that came with your OSX disc are very old, most likely you are stuck with 19x.xx drivers where as current version is already above 28x.xx.
Also you probably stumbled upon a problem with drivers downloaded from Nvidia.com which give you error when you try to install it. So here I compiled a short guide in how to update your drivers.
1. Driver Nvidia 259.47 ( found better performance with this one) for Windows Vista/7 64 BIT ONLy!!! http://laptopvideo2go.com/nvidia/255series/25947_win7x64.exe
Same driver but for windows Vista/ 7 32 BIt Download here
http://laptopvideo2go.com/nvidia/255series/25947_win7x32.exe
2. After you have downloaded drivers you will noticed that they are packed with 7Zip archive (self extracting), unpack it (just remember the location).
3. Download the modified .INF file 64 bit system
http://laptopvideo2go.com/infs/255series/25947_win7x64/nvbl.inf
32bit System
http://laptopvideo2go.com/infs/255series/25947_win7x32/nvbl.inf
NOTE: Even though they have the same name, 32 and 64 bit .INF files are different do not mix them up.
4. Place the .INF file in the same directory as you extracted the driver package, IT WILL SAY THAT .INF FILE ALREADY EXIST, CLICK YES TO REPLACE IT WITH THE ONE YOU DOWNLOADED!!!
5. Run the setup.exe (if your acc is not admin, then right click and press Run as Administrator), proceed with the installation.
6. Message will popup at some point that it cannot verify publisher blah blah blah, press proceed anyway.
7. Sit back this process will take longer than usual driver installation but it will succeed, dont be scared.
8. Just reboot and you are ready to go
P.S also note I wasnt able to find XP drivers so I suggest you move to Win 7 as XP getting less and less support from microsoft, however I think if you can find this drivers on nvidia website for WIndows XP *Just make sure its the same 259.47 drivers, it should work.
I have done it on MBP 13 2010 but this INF files supports ALL apple nvidia based GPUs
Good luck
