Yes you can if you download the driver e.g. here.

 

The drivers on the Nvidia site won't work with Sony Vaio laptops, its mentioned somewhere below where you click to download it. Sony for some reason does not want its customers to have access to the Nvidia driver updates.

Because of this you have two option: laptopvideo2go.com or get the drivers off sony e support.

 

or you can modify the official Nvidia inf yourself (not that hard) to make it install in your Sony.

 

Not without breaking driver signing, and having to either turn off large parts of the Vista security features or live with two requesters on every startup.

 

i downloaded the nvidia driver at laptopvideo2go.com but i also get the same error. So i should just go to sony vaio site to download the driver ? sorry i am noob in these kind of stuff >_<

 

Why don't you use my link?

 

sorry man, i will try now =)

EDIT: THANKS MAN IT WORKS NOW ! i love you !! ( no gay ) XD thankss !! +rep

 

Rajeesh,

Would you mind posting the instructions for doing this modification. Maybe in a separate thread. And does you method mitigate the issue that arth1 brings up?

Gary

 

I will post the instructions soon. Modifying the driver inf invalidates the digital signature associated with that inf and so the digital signature is not valid for that modified inf. Vista will pop up an alert saying "the driver is not digitally signed" only during installation. The alert can be safely ignored in a 32-bit OS, but not in a 64-bit OS, which enforces driver signing and you cannot install the driver in a 64-bit OS.

 

You're welcome.
