Can't play (The Witcher 3: Wild Hunt)

I bought a license, threw the save and started H + The problem is that after about five minutes of the game, the game hangs tightly, the sound in the game is heard, and then crashes. At the bottom right, the video driver has stopped responding and has been restored. Before that, I played six months ago, everything was normal. Who faced this help !!!
