Windows not recognizing NVidia GeForce 8400M GT

Torrentn thanks for the Inf file but I do run windows 7 64bit. Can you revise the inf file for 64 bit windows home premium. Sorry for the inconvenience.

Rar the inf you want me to edit and attach to a post. Download from NVidia's site for desktop model first, if you don't have an installer package. You can overwrite the .inf with mine when I post again with it.

Torrentg, I am new so do not know my way around this forum yet. Thanks for the inf file but I forgot to specify I am running window 7 64bit so it did not work. Can you make a correction for me? Thanks for all of your help and sorry for the inconvenience. Take care

Torrentg here is the Inf. file you sent me previosuly. I have already downloaded the latest nvidia mobility drive so I am just waiting for your new inf file. I am using windows 7 64 bit. Thanks

You're welcome but see my previous post. You have to download for your model of card, only tell it for desktop model (without m) for Win 7 x64.

Then run it and extract to C:\NVIDIA - close when extraction is done. Installer not needed any longer.
In there someplace will be the inf you have to use Winrar on and attach the .rar to a post.

Drivers - Download NVIDIA Drivers

You're going to have real problems with this anyway because of driver enforcement. You really should be running x86 Windows.

I'll edit it for you and the rest is in your hands. You can download, replace the original with mine and install using the device manager like I tell everyone else.

You'll be waiting quite a long time if you don't reread my previous post better.

Nevermind. I'll make it happen. Give me a few (I'm feeling kind today.)

Here's your .inf - look at my posts to other people and install the exact same way. Make sure you copy and paste this .inf over the original one that you just downloaded and extracted somewhere in C:\NVIDIA

Torrentg, attached is the inf file I download form nvidia desktop as per your instruction. ALso here are the properties of my display driver if you need them again:

PCI\VEN_10DE&DEV_0427&SUBSYS_9008104D&REV_A1
PCI\VEN_10DE&DEV_0427&SUBSYS_9008104D
PCI\VEN_10DE&DEV_0427&CC_030000
PCI\VEN_10DE&DEV_0427&CC_0300

Thanks again for all of your help

Torrentg, I download your latest inf file and downlaod nvidia driver 191.07 extract your inf file and replace the nvidia one with your, update the drive with your instruction choosing 8400 gs but it keep giving me error that the video card is not supported. I tried it many time to no avail. ANy suggestion? thanks

Hi Torrentg,

I have exactly the same hardware id as Vaio 77 above post:-

PCI\VEN_10DE&DEV_0426&SUBSYS_9016104D&REV_A1
PCI\VEN_10DE&DEV_0426&SUBSYS_9016104D
PCI\VEN_10DE&DEV_0426&CC_030000
PCI\VEN_10DE&DEV_0426&CC_0300
Sony Vaio VGN-AR51E laptop.
I have just upgraded from vista 32 to w7 but took across all my files and settings - did not do the clean install. Well I have pasted your NV_DISP.inf in the NVIDIA driver folder for the latest desktop driver 191.07 and followed your instructions to the letter. WellI get an error message at the end:-
"Windows found driver software for your device but encountered an error while installing it.
NVIDIA GeForce 8400M GT.
The system cannot find the file specified ."

I wonder what you could suggest?

Thanks,

Ray
