This problem started a while ago . I noticed that sometimes , in overwatch , my fps dropped from 120-140 to 50 . I didnt really care at that time because it didnt really annoy me . Now it got worse . This happens is almost every game and the fps drops to 20 I noticed that when this happens the audio also gets distorted . I tried reistalling the games , windows and nothing has worked so far . Any clues on what i should do ?
