Okay honestly I don't even know if it's my motherboard to begin with. It could be my HDD, RAM, or even my APU and GPU getting mixed up, I don't know. Thing is, I can't restart my computer to get updates done and it's really going to kill my system if I can't. Why is this happening? What is causing this to happen?
