I would like to save you some time. When you have a problem, reboot and see if it goes away. And I am not talking soley about computers. Phones too. Shut them down, all the way down, then start them again. Your car. Weird noise? Turn off the car, then turn it on again. Yourself. Go take a nap, then get up and try again. There is almost nothing in life that is not made better by rebooting.
