i reformatted my gateway notebook and when i try to install nvidia it keeps me telling this the graphics driver could not find compatible graphics hardware
go to nvidia.com and then go to driver download option it will have 2 options 1 is manual serach driver and other is auto search click on auto search driver then download it and then i think you will be fine with that driver
if you're using the driver from nvidia that could be the problem... Laptop OEMs change the video drivers and often do not permit the regular drivers to be installed. check Gateway's website for the driver provided by them.
