Windows 7 32bit seeing Nvidia 8400M GT as Standard VGA, Sony Vaio

Hello All,

I've searched the forum for threads relating to this and have had a modicum of success, but am still not all the way to solving this prolem.

My System:

Sony Vaio VGN-FZ38M
Windows 7 Home Premium 32bit
Nvidia Geforece 8400M GT
Drivers tried - 306.97

I've inspected the Device manager and got the following device ids


In the Nvidia driver folder I've found the files:


... and I've edited them as suggested.

ListDevices.txt now has the following edit:

Red entries are my edits. As you can see in nvmt.ini I've copied the Section numbers from the previous entries, as in:

%NVIDIA_DEV.0426.9005.104D% = Section006, PCI\VEN_10DE&DEV_0426&SUBSYS_9005104D

I've had some limited success...

My system now sees the GPU as an Nvidia 8400M. So far so good.

However I'm still getting error messages.

Firstly, on reboot, the system stops the card because of driver problems.
Secondly, if I run the Nvidia software, it says the monitor is not connected to an Nvidia card.
Lastly, if I update the driver, it reverts to Standard VGA in the Device Driver list.

So, It looks as if I need to do more.

My immediate thoughts are:

1) Should I be editing the nvmt.inf file, or perhaps another one - nvmm.ini or How do I know which nv??.inf to edit?
2) In the nv??.inf file, I have no idea which 'section' to point at. I tried 11 and 12 as seen in another thread, but got the same issues. So I tried the same section entries as the next most similar card, but to no avail.

Any help would be appreciated!

Hi Roger and welcome to W7 Forums

Where are you getting the driver from? Normally, I would say to go to the hardware manufacturer (in this case NVidia), but with Sony Vaios (and some other manufacturers as well) you need to go to the laptop manufacturer instead. This is because they customise the drivers so much that only the drivers that they supply will install.

Hi Dwarf, thanks for the reply. The driver file is the same either from Sony or Nvidia.
