Windows 7: Windows 7 and NVIDIA GeForce 7400 Issue

Windows 7 and NVIDIA GeForce 7400 Issue

Hey Guys,

I've done quite a bit of searching about and while this seems to be a common problem I can't find a solution that works! Would appreciate any help that can be provided.

I did a clean install of Windows 7 Home Premium and it's not recognising my graphics card which is a built in NVIDIA Geforce 7400 on my Sony Vaio (VGN-SZ48GN). In its place is listed 'Generic Non-PnP Monitor on Standard VGA Graphics Adapter', which displays as 4:3 instead of widescreen. Very frustrating.

I have tried the following -

1) Getting the newest drivers from NVIDIA - Does not complete install as Windows fails to recognise this is the hardware I have.

2) Uninstalling the display adapter in 'Device Manager' - Reinstalls the same generic card on reboot

3) Using the old drivers in Windows.old - Already says I have the best drivers for my device.

Please help!!

Hey, i can understand your frustration but have you tried installing any other operating system other than windows7. Other probably would be monitor but I guess your system is new. I had some issue with Nvidia MX400 but it was due to my old monitor. I would suggest you to try installing other OS like XP,vista and let me know your feedback.

PunkedbyWindows, welcome to the forums.

This isn't a Windows problem but a Sony problem (or most laptops for that matter). In most cases the reference driver from the video card manufacturer (Nvidia and ATI), while it installs and works no problem with the desktop versions, for the laptop versions you are usually stuck relying on the laptop manufacturer for the driver.

In your case from looking at the driver page for your laptop,

VGN-SZ48GN : Downloads : Support : Sony Asia Pacific

it would appear that Sony basically stopped support for it as far as drivers go at XP. One thing you can try is the driver from here,

NVIDIA & Laptop News | Latest NVIDIA drivers and related news |

It comes with a modded INF that allows it to be installed on just about any laptop video card.
