Most of the notebook drivers for nvidia doesn’t work for the specific notebook models like Asus, sony, msi, lenovo, toshiba, dell etc. I don’t know why nvidia doesn’t support specific graphic cards for hardware manufacturers, but it seems like they have given up on the driver support part from notebooks. Well I have made a Asus K53SV Review, and the driver I downloaded from their support website was old a few months and I couldn’t run any game or benchmark properly. Other users reported the same.
As per request, here is a modified nVidia Notebook 270.61 driver for Windows 7 and Windows Vista 64-bit. If you want to do the same procedure by yourself here you can Fix Nvidia Notebook Driver. It’s not as complicated as it looks like and it is worth the try.
