Basically, this started with my GPU making a loud noise because one of the fans was a little off of it's bearing. Along with this, my PC wouldn't boot. The monitor would stay black. I switched out the GPU for an old crappy one, and it still won't boot. Finally, after maybe 30 seconds of not working, the computer's CPU fan goes to what seems like maximum speed and stays there. Everything seems to be plugged in fine, does anyone know what the problem could be?
