Quite recently, I finally deleted all my Nvidia GeForce driver stuff since I had changed to AMD. One of the deletions required that my computer be rebooted. So, I rebooted , and Windows 8 started up with a black screen. I could use the cursor, but couldn't do anything with it, and I saw the network (I think) sign on the login page blink at random. I rebooted my computer, and was able to boot into safe mode with networking, which is what I am using now. Obviously, the screen is working in safe mode. I have a backup on an external hard drive, so I tried to replace certain files regarding the NVidea stuff I lost. Unfortunately, it seems as though I might need to replace the registry as well, and the driver folder too. Also, since I am in safe mode, I can't install any new AMD or NVidea drivers. (I wouldn't have been able to install the NVidea ones anyway) Does anyone know how to fix this problem? To me, it seems very much like a driver problem, and maybe even a registry problem.
