built this system about 2 weeks ago everything is working great !! one thing i noticed is that there is always one core of the 8 core that is always running at 70 to 90 % when my pc is at idle !! Now if i look in task manager and go to processes, there is one that is called system idle process, image name i guess its called and the description of it is this (percentage of time the processor is idle) !! there is a number beside that and its between 80 and 90 all the time !! its really anoying, do i need to learn to live with it or can i stop it ?? it wont let me end the process either !! does anyone know what i'm talking about at least !!
