Question Monitor goes black..

[_tafpi_]

When I play games on 'fullscreen' and press any buton, my monitor turns black for 1-2 seconds . Every time I press any buttom this happens . This happened today for the first time . I downloaded an update of my GPU ( rx 570 ) so I can fix the problem , but instead of getting it fixed , now , the probelm appears on 'windowed fullscreen' too... (games I played : LoL , csgo) . What is wrong...?!



Ps. Everything works normal on google (YT videos etc.)
