Windows 7: Hi all. Need solution for my graphic card problem.

Hi all. Need solution for my graphic card problem.

Hi all,

I am using a Sony vaio laptop VGN-SZ75GN. I recently upgraded my windows vista busniess 32-bit to a windows 7 ulitmate 64-bit using a clean installation.

I have a external graphic card which is NVIDIA® GeForce® 8400M GS notebook graphics processing unit(GPU) (SPEED MODE) / Intel® Graphics Media Accelerator X3100 (STAMINA MODE). After installing Windows 7, it couldn't detect the graphic card. This was done by looking at the device manager saying that it only detected a stardard VGA Graphic Adapter. I tried to check for updates, but it said that the stardard VGA Graphic Adapter was the best driver software. I looked around the forum like a headless chicken and couldn't find a solution for my laptop.

Can anyone find a solution for my problem? Will be very much apprieciated.
This are some of the pictures of my laptop's specs.

Yours Sincerely,
Legendation.

Hi Torrentg,

I cannot seem to find NV_DISP.inf anywhere? Thanks for the fast response.

You're welcome.

If you ran the .exe that you downloaded in step one, it will have extracted to C:\NVIDIA folder.

The exact location of the .inf is inside this folder -

C:\NVIDIA\DisplayDriver\191.07\WinVista_Win7\English

Make note of that because you will have to click on it as part of the install process, after you edit it.

Let me know how it goes for you and also take special note of the condition for this to work for x64 users, in the OP.

I had the EXACT same issue with 2 different chips. Install the old vista drivers in compatibility mode, reboot, then run the new drivers. Use the uninstaller first from the new graphics card. I wouldn't recommend disabling driver enforcement. It has its uses in a 64-bit environment.

Hi torrentg,

I have extracted the driver file. This is the location -
Local Dick ( C : )-NVIDIA-DisplayDriver-186.81-International...
In the international folder there are Display folders, HDAudio Folder and other files. Dont' seem to see the NV_DISP.inf file.

Go to C:\NVIDIA

In the top right search box, enter *.inf then hit enter.

Hi torrentg,

Sorry for the mixed up. The driver that I'm suppose to install is the desktop driver? So if I have a 8400M GS, I'm suppose to download the 8400 driver?
Thanks for the response. Hope to hear from you soon.

Yes. Follow what it says in the link I posted in #2 above.

You're going to have slight problems because of the intro to the post there, but you really should have installed x86 version on that machine. If you follow well, will work well though. Look down in the thread for how to disable driver enforcement.
