I am going to re-install Windows 7 as I would like to completely delete old drivers that were there due to an old motherboard. I backed up all my information from the hard drive with windows existing on it, but I'm unsure that when I restore all this information and files that it will restore the old drivers? I have been told that re-installing windows is the best way to completely remove old drivers but I do not know that If I back up the hard drive with them on, it will restore them again?
