I have installed the driver of the 9600 GT from the official site of the Nvidia. I have installed the 258.96. version at the time of installing it giving me the error of installing the driver in my computer system. I am having Intel core2duo processor and windows vista operating system running on my computer system. I am unable to get what exact problem I am facing with my computer system at the time of installing the driver. Do anyone have the same problem same as me. Please suggest me the solution. Thank you in advance.
