Iron

At one point, the video card on the Lenovo laptop stopped working / is loaded.

Brief characteristics of my PC:
Processor: Intel Pentium N3710 1.60GHz
Video card: Nvidia Geforce 920m 2Gb
RAM: 4Gb 1 chip 1666MHz

When I run any application or game through a discrete video card, it almost does not load 0-1%.
It became sudden. In the evening I played CS:GO after I turned it off and then the PC itself. The next day I went to a friend with a laptop. We wanted to play online games with him. When I went in, the fps fell by 40-50. The download took a very long time. It was the same in other applications and games.

Please, help!
