I reccomend you to update your bios to latest and play games and post the task mgr image here.

Already did that and still the same, the game that has worst fps is la noire the cpu goes 100% and the gpu stays in 16% when minimize to check the gpu ussage a couple of times i gain fps and the the gpu goes to 60% but then goes down again, could it be a faulty motherboard or cpu
