But there is problem since vga drives for my graphics card NVIDIA GEFORCE GTX 960M I dont have driver support I can make gui components work faster. can any one give a like to download the drives that may be compatible with my os(written in c++ and assembly) so that I can start gui. I will be really thankfull for any help.
