Hi. Three days ago while working with a computer, he dramatically showed me a grey screen and showed no signs of life, after rebooting from a sin far away I ran it in safe mode and everything seems normal. When re-reboot in normal mode it does not boot, after loading Windows the screen remains black and keyboard does not work. Restart and again in safe mode, everything is normal. Decided that problems in the driver video card update I did. Using the utility amd completely removed the driver, then downloaded from the official website fresh, put, reboot, the story is the same as in the beginning, black screen, keyboard not responding. If you fully removed the drivers for the video card the PC is functioning fully. What do I do?
