Sony Vaio VGN-NR21Z laptop Windows 7 NVidia 8400 Video Driver required

[misphit2011]

Hi all, I have just installed Windows 7 on to my Sony Vaio VGN-NR21Z but can't seem to find the correct drivers or be able to install them. Every time I check on Device Manager it just says " Standard VGA Graphics Adapter" and not "NVidia 8400M GT" as it should.

Please can someone help me find the correct video graphics driver for my laptop and tell me what method to install it.

Thanks I really appreciate it.

Hi misphit2011,

Assuming you have tried to install the original Vista driver (that is available from Sony Support site) and this hasn’t worked you will need to resort to a driver from Nvidia plus a modified INF file that will allow an install on an OEM system.

Have a look at the following links and be sure to read the quick start guide towards the bottom of the page on the first link.
