The Motherboard is the largest component in your PC and the Central Processing Unit is its brain. But when your input devices go on the blink, you're shut down for awhile. When Computer Mice problems come, we do not panic as fast when we can not access our hard drive.

When you grab your mouse and either click or roll the buttons and nothing happens, your computing fun stops. Even though the mouse is a little input device, you will wish you understood its every aspect when it dies.
