Windows 7: Standard VGA Graphics Card and Generic Non-PnP Monitor.. HELP!!

I recently updated my windows vista to windows 7. But for some strange reason windows 7 wont recognise my graphic card :S

The graphic card i have is NVIDIA GeForce 8400M GT,, and i have tried to install the drivers from NVIDIA website but it wont let me install.. it says "NVIDIA Installer cannot continue" and at the bottom is says "This graphics driver could not find compatible graphics hardware"



When i go on Windows Experience Index.. everything seems to be fine except graphics and gaming graphics:
Processor: 5.1
Memory (RAM) : 5.1
Graphics: 1.0
Gaming Graphics: 1.0
Primary Hard disk: 4.8

Can someone please help me out as i can not find any solutions to this problem and i just upgraded to Windows 7 yesterday so i would like to experience how it is really like e.g. Windows Aero..

and can someone show me screenshots if they have solved this problem? if someone knows how to solve this please let me know ASAP..

Thank You

Let me guess, a Sony or Toshiba laptop. If that is the case then the drivers directly from Nvidia will never install on it as neither of them will allow it. The only way to install something other than the driver from Sony or Toshiba (which really is nothing more than the reference Nvidia driver modded with the device IDs that Sony and Toshiba use, and whatever extra bits if any to work with the display on the laptop) is to use a modded driver. You can try one of the ones from here,

Drivers | drivers for mobile cards and laptops | laptopvideo2go.com

Go for one from the 275.xx and down as I haven't seen too many saying much good about the latest 280 beta driver. If those fail to install you can always use whatever Windows 7 or Vista driver (the Vista driver will work in Windows 7) from your laptop manufacturer.
