Hi all, I've recently bought an Alienware m15x second hand, and it came with a HD5870 graphics card. I've since found an Nvidia 680M that I want to install. I've done the physical installation OK, but no Nvidia driver will recognise the adapter is present! Currently Windows 7 recognises only a standard VGA adapter (because the drivers aren't loaded of course).

I have tried editing the INF file as per instructions here - http://forums.guru3d.com/showthread.php?t=377158 but it hasn't worked. .I'm not sure what else to do? I've tried a few different NVIDIA drivers, all don't pick up the 680M is present.

I'm running WIndows 7 Home Premium and my Bios is already A09.

Help? :)
