When i play games cpu normaly in big games is used 99% the max. Now i cleaned it, re applied thermal paste and it goes up to 100%. When it hit 100% the game start to lag and fps drops, when its 99% the game works 60 fps and up. Only when it hits 100%, but before it never hited 100% while gaming only 99% .Did anti virus scan, degfrag, check disk all the things not working. Using win7.
