4 Vocabulary Paragraph

Hi I am sitting at a computer trying to figure out what is up with this computer. I have to unscrew and check if all the circuits from the motherboard are correct. I think the output devices does not have to do anything with it. So that is out of my list. The CPU may be the part of the problem like the mother board. The input device should not be part of it unless the wires are connected to the motherboard. I guess I have to switch to another computer and have an adult fix it.
