My 3rd gen i3 laptop has: dead battery, broken screen(about 1/3 of the screen is dead), loose USB ports that work when they feel like it and a decrepit HDD that was slow even when it was new. I have it for emergencies, but I don’t think it’s worth rebuilding it.
My father does this as well. And it’s always the computer because it’s old and it plays tricks on him. He’s never done anything wrong!
