Hello I have a upgraded prebiult Pc with a fx4130 quad core cpu and a new gtx750ti. And recently when ive been baming my PC will just freeze randomly when I play games. For example I will be playing Black ops 3 and mid game my screen will freeze for 35-40 seconds and resume like nothing happened. That botherred me alot so I quit playing it and tried to play some Skyrim the other day and every time i'd try to do something it would freeze up. Specifically when I tried to go to the menus. When these things happen usually a short bit of audio would repeat. Like if I was firing my gun in Black ops it would be that noise constantly. Or sometimes i'd be in a Skype call and i'd hear their voice over and over. If I were to buy a cpu like the fx6350 or 6300 would that fix these problems. Also could my hard drive be to blame. My hard drive seems to be very slow at times. Im not sure what brand it is or anything. Also how easy would it be to switch all my stuff from one hard drive to another.
