So I don't know what is the term to explain my problem but in random times I use the laptop (It can be while gaming/normal browsing, or any laptop work), it would suddenly lag for 1-2 seconds. The lag affects mouse movement, and the stuttering sound (to best describe it its like when you play a game and it suddenly dropped to 1 fps for a split second). This problem occurs randomly, sometimes in a session I use my laptop for a long period of time it happens, sometimes it doesn't happen at all. Any idea on what causing this? If there's any more information I need to provide please feel free to ask and mention them. Thank you very much
