My Monitor Lose signal when playing video games

My Monitor randomly lose signal when playing video games and I can hear the sound of a disconnected USB when this occur, also I can still hear the sound of the game running on the backgroud for a minute or so and I had to hard reset my Computer by pressing the power button to turn it off and then restart . I checked my CPU and GPU temperatures and they are just fine never got above 60C, I changed the thermal paste for both of them.
