i got this gtx 980 and i7 3770 , 8 gb ram and it stuttering like hell in aaa games, because of the old hdd i am sure,when i am playing it always gets to 100/100 and even when i start the pc it sucks as hell with a 100/100 usage, can it be fixed, i tried defragment, disk doctor, and in hd tune it says that my 250 gb hdd sector is damaged, btw it gets to 56 c heat.... so it's a new hdd or nothing ....right ?
