I recently went to install a argb hub and plugged the wrong power interface into it instead of sata. It burnt out the hub but the pc kept working. A day later pc shuts off by itself. When I try to turn back on everything lights up fans run but nothing on screen. Eventually I get a screen that says it's going to start in safe mode or press f1 for setup but freezes at that screen. Is this definitely the psu or could it be the motherboard? How can I test to find out?
