AMD technical support staff Hello, I'd like to ask a question. My graphics card driver updates, playing some games seems to appear black screen, no response. This part of the game refers to, for example, China's online games, the best speed OL, I think you have also heard, low version of the drive, it seems that this will happen. I search for solutions to this problem in the network, the solution was obtained in the control panel inside the closure of overDrive, I do not know whether this method is reliable, but I know the update for the latest driver will be black. A few weeks ago sent an email requesting AMD global technical support, but it seemed they didn't reply to me. So I hope you can help me with this problem and give me a solution. Thank！
I don't think so, but I need your help. The AMD global service center has given me an answer to determine if a part of the game black screen may have been caused by insufficient power supply. So how much do you think the HD7700-4G video card needs to be powered by W?
