Driver problem

Im on my little brothers pc and i saw that he had a black border when he uses a hdmi. I looked but the pc didnt have catalyst control center to fix the issue. I ccc but it seems i dowloaded the beta. Heres where things get weird. With thid type of control center comes a bug that on certain pc's makes the screen black and white. After researching on what to do i downloaded display driver uninstaller that would fix the problem. Only the program stuck or something and when in tried to restart the pc it wont start up again. Did it delete all the drivers?
