Ok so like, I just had to get a new hard drive, yesterday I talked to Microsoft and they got me my windows 8.1 activation key. Now I'm trying to get a graphics driver because it just says I have the windows thing. Now whenever I use the auto detect thing and click download and try to install one, it never actually does anything. Usually it either fails or it just says it installs and asks me to restart, which I do, only to find nothings changed. Why?
