Hello Everyone, I am facing a serious problem with installation of my CUDA driver with Nvidia card for my Sony VGN-AW41ZF/B, so I am just posting the posting he problem faced by me during installation. I have a Sony laptop i.e., VGN-AW41ZF/B . and whenever I tried to install CUDA Toolkit 4.0 driver and Notebook developer drivers for the Windows Vista and Windows 7 , I always use to get a error message that “the graphics drivers couldn’t able to search for the compatible graphic hardware” and all comes to end here. So what the exact problem is this ? does anyone have any idea about this. please help!!
