I can not speak English well but i need some help.
Before 2 or 3 days ago, i saw a update on AMD Radeon HD 6800 Series (6850) display card. so i tried to update my card. after that my screen was black. i tried everything but i cant fixed it. i opened my computer in safe mode and used some programs to delete my driver. after delete i opened my computer normally but when i install the driver again screen turned black again. i tried formatting and download driver again. i think that was fixed but my screen is turned black 2 times again. is it about last update? i cant find what the problem is. can i fix it permanently?
