Just got a new graphics card today, I uninstalled the amd graphic control center along with all the drivers. Restarted then powered it down. Then I installed my new R 290, boots up and my keyboard and mouse are powered on, however when it gets to the login screen they dont work and no longer have lights on. How do I system restore, I have key board and mouse control in the biios and entering into safemode does not work either. How should I resolve this problem ?
