GeForce 8600M GT Vista

I got a Graphics Card GeForce 8600M GT 256 MB and I’m having some issues about updating it.
Due to windows update system Its updated with latest driver possible but as I can see, current driver is old and there are newer drivers available.
I tried manually downloading the driver to my computer and installing it but It failed because Asus requires it to be downloaded from its own website so I tried to do that but didnt work at all. It says there is no proper card plugged in. So I tried it to update from control panel, but It says ‘latest driver is already installed’ again.

I will send my DxDiag and msinfo files hoping that they may work to identify the problem
