I have six usb ports so I started moving my mouse and keyboard around to the
other ones. None of the ports in the back seem to allow me to click on anything
but I can move the mouse and scroll. And the keyboard can sometimes activate a
item (clicking enter).

I just discovered that the front usb ports though are working for both my
keyboard and mouse and I can click on things and work again. But how do I
trouble shoot the rear ones?
