You have 64 bit Windows and unfortunately Asus only has that for 32 bit. With that said your laptop has a Nvidia chipset in it, 610/7000M. No promises as it is for the Nvidia desktop chipsets but you can try this, NVIDIA Nforce 15.53 WHQL Windows 7 64-bit download from Guru3D.com
which may or may not install. It may in that I had a look at the INF's in both it and the one from Asus, and some of the device IDs from the Asus driver are in the reference Nvidia driver. If yours happens to be one of those that is in it, then it should install no problem.
If it doesn't install then it might be possible to get it to install by adding the rest of the device IDs from the Asus driver to the reference driver.
