Solved Nvidia GeForce 8400M GT not found after Windows 7 64bit install

[TwoCables]

I apologize for not catching this in time. You have to run "setup.exe" which is located in C:\NVIDIA\DisplayDriver\(version number goes here)\WinVista_Win7_64\English. Or another way to say it is, you have to look for this:

So do the .INF file again and then run setup.exe. It should work perfectly.

I have followed all the steps for downloading/extracting the driver and the INF file stuff for driver 302.77.

After modding the INF by copying and pasting the info, I clicked the setup.exe but the installer still says:

Nvidia installer cannot continue.
The graphics driver could not find compatible graphics hardware.

Should I try downloading an earlier driver and trying the process again? if so would I need to delete the files that have been extracted by the other driver downloads.

It might be easier than we think. The .INF contains the version number at the very top of the document. You will also need to make sure the path to setup.exe matches the version number. For example: C:\NVIDIA\DisplayDriver\302.77\WinVista_Win7_64\English

It's important for the .INF to be for the exact same driver version as well. So if everything is matching up and this is still happening, then I don't know what else to try. I mean, if he's right about the reference driver not being able to install without some fancy trick like this, then it would mean that you'd have to keep trying things until it works.

Wait a minute. The name of the .inf file is supposed to be nv_disp.inf.

Basically, I have gone to this website LaptopVideo2Go: Drivers

then in the search terms the first box needs to be filled 0426 and the second box 3016104D. Then I also clicked for only windows 7 64bit drivers.

I have followed the page to where u can view the modded INF, and looking at it I haven't seen anything wrong with it that doesnt match to the driver its associated with on the site.

I know nothing about all this though so if you can view the INF mod that is associated with the driver and see if it does indeed match fine then that would be much appreciated. I am going to keep looking through the modded INF to look for any mismatch.

There is no such file in the relevant folder, the only INF file is the NVDM.

Should I try a different driver number and see if one is created after attempting the install for it?


Before i download another driver should I choose the most recent one available or an earlier version??

What is the path to your setup.exe file? Does the version number in the path match the version number of the nv_disp.inf file that you downloaded?

Maybe what you're supposed to do is just download their setup file for the driver. I sorted only by Windows 7 64-bit and here's the latest WHQL Certified driver:

http://download.laptopvideo2go.com/nvidia/300series/30292_win7x64.exe

This may not require you to do anything but install it.

I am downloading that driver as we speak. I have started from scratch and deleted the 302.77 Folder from C: > Nvidia > DisplayDriver

After download/extraction, I will attempt an install using the setup.exe, which will show the error message I mentioned earlier, but then that should create the nv_disp.inf file right??.

I have just clicked on the download modded INF file for the driver you suggested, but it says it is not available??

Should I try an earlier driver which has the modded INF available?

This installer might not need any fancy tricks. It might work as it is.

Regarding the other installers you've downloaded so far: were any of them from this LaptopVideo2Go site?

 

[conorgreen]

By installers, i mean the setup.exe that you showed the icon of earlier. And yes they were all from the same site, as they are extracted from the downloaded file.

Once the file is downloaded it extracts itself into my downloaded files as a folder, then i cut that folder to C: > NVIDIA > DisplayDriver. so its inside DisplayDriver folder.

 

[conorgreen]

I just ran the setup.exe from the extracted driver 302.92, and the error message appears as it did before. But no INF file is created in the folder after.


The whole aim was to have DirectX 9.0c installed, but because my graphics card was not detected, installations kept failing etc.

I see what's happening now and now I know why you grabbed 302.77. Try this. If it's what you've already done, then I apologize for the repetition. This is new to me too.

1. Download 302.77 (from LaptopVideo2Go's site) and extract it to anywhere you want. It doesn't matter where it gets extracted to. It also doesn't have to be inside of C:\NVIDIA\DisplayDriver.
2. Right-click this and choose Save As: http://www.laptopvideo2go.com/infs/300series/30277_win7x64/NVDM.INF
3. Save it to the the extracted folder in order to overwrite both of the existing NVDM.INF files located in the same folder as setup.exe and also in the folder at 302.77_win7x64\Display.Driver
4. Run the setup.exe from inside the extracted folder

If this doesn't work, then I think I'd have to admit defeat.

 

[conorgreen]

With number 2. is it Save Link As? then i just save it into the extracted folder and it should overwrite both the nvdm file in that folder and also the one in displaydriver, or would i manually have to save it again in displaydriver?

You could save it once, and then copy it and then paste it into the Display.Driver (not "DisplayDriver").

For me, these the paths to both NVDM.INF files:

D:\My Documents\Setup Files\302.77_win7x64

D:\My Documents\Setup Files\302.77_win7x64\Display.Driver

So, it just depends on where it's located. After that, you'd run setup.exe from inside of the folder named "302.77_win7x64".

 

[conorgreen]

I saved it into the folder that setup is in (the base folder) and it prompted to accept the overwrite, which i did.

when i copied into the display.driver folder there was no prompt. but the file is now saved there too one place underneath the original NVDM file that is there. should i get rid of the original file so its just the new one saved in display.driver? then run the setup?

The file type for the original NVDM file says setup information, whereas the new NVDM file type shows Firefox HTML Document, is all this correct?

 

[conorgreen]

I just clicked the link for the INF file for 302.77 and it says the file is not available. So could this be why its not working yet?? Would a different version driver with the modded INF available work?

There shouldn't be an original because you told Windows to overwrite it. As for there being no prompt for the Display.Driver folder, that means there wasn't one there to begin with.

However, what you said below might explain it:

The file type for the original NVDM file says setup information, whereas the new NVDM file type shows Firefox HTML Document, is all this correct?

I didn't know Firefox would do that. I need a few minutes.

Edit: Oh, they don't allow linking on forums and other outside types of linking. So you have to go here: http://www.laptopvideo2go.com/drivers/win7x64/302.77/disclaimer

Right-click the link for the INF file and choose "Save Link As" and save it somewhere. After that, rename it and remove ".txt" so that all that's left is "NVDM.INF". Windows will ask you if you're ok with doing this because it might become unstable (which won't be true for this file). So say Yes and it will change instantly. This is the file to copy into both of those folders I specified.

 

[conorgreen]

I think because the link doesnt work, it hasnt worked properly. because the file is called NVDM.INF and the file type is shown as firefox html document. i will try a different driver update to one that has a moded INF available n see if it works.


The new driver I will try is 301.40. I have it downloading now, can you create a link for the INF like you did for the previous driver as I dont know how to do this.

 

[TwoCables]

I ninja-edited you.

 

[conorgreen]

So can I copy what comes up when i click download modded INF and paste it into the file NVDM that would appear in the 301.40 extracted folder like before and do the same for the display.driver nvdm file.
