I have a laptop with graphics card amd radeon hd 7640g worked for almost 3 years and 1 day the driver took off. None of the games will not start. I pereustanavlyuvav vindovs. W 7, W 8, W 10. Put them in the driver anyway but did not start writing that the drivers are installed and in Device Manager indicates that the video card is not opiznana not connected. What to do?
