1- When uninstalling the drivers, the mouse and keyboard work perfectly, these drivers are loaded at startup with windows, ati driver is only for display, and without the screen works the same, but could not use a pc new no?
2- You open the ccleaner, you'll destildas tools >>> start and everything having to do with ati.
3- reboot the pc and start it in safe mode (depends on the mother but usually by pressing F8 before Windows loads), then uninstall the ati driver from the control panel or from the same ccleaner. 3- Then manually delete the folders in both program files in arch. prog (x86)
4- Start menu, Run command, typing "regedit" without the quotes, and the tree hkey_local_machine >> software delete ati tab.
5- spend the ccleaner normally and longer.
6- reboot the pc, the normal start it and come back to install the drivers, so you have left a clean, residue from the previous version installation.
