Hi, i have a AMD radeon HD 6850 and 1 week ago i started getting black screens at boot up.I reinstalled the Windows and everything was working fine untill i tryed installing the AMD driver 14.9. After that the same problem after windows logo i get black screen but the system is still working and there are no strange sounds .I uninstalled the driver with DDU and tryed installing a older version and the same problem occured.Anyone knows how to fix this?
