My CPU was fine but i'm having a problem now i did a test with the problem that i am having. I started playing a game and then when the lag problem started i notice it was my CPU. The CPU usage was at 65-70% used and all of a sudden it drops down to 27-33% for like 2-6 seconds,then it goes back to normal 65-70% , the problem is very constant it happens every 3-6 min Please some one help and excuse my grammar
