Ok my problem started this weekend. My PC is really sluggish when I try and play my games now. I have real bad stuttering and loading game levels like Titanfall is taking a lot longer then it used to. Quiting a game to desktop takes a lot longer too. Would a dying psu cause this. It is 6 years old. My hdd is just over a year old. And I also notice it is at a 100% in system monitoring. I am using Windows 8.1 I did virus scans. Used ccleaner and nothing helps. Any ideas would be appreciated.
