When ever I am doing anything on my computer there is always a few times when my screen will just freeze I usually still have audio and about 30 seconds to a minute later it will unfreeze as if nothing happen. I have built a whole new computer and the only part I have kept is my hard drive and GPU. I have no idea what is causing this but I am going to guess it's my GPU? (yes I still had this problem before the new system build and after)
