I get why restarting your computer is the “go to” thing to try when something is not working on your computer. But if it has to do with your computer’s peripherals (i.e., keyboard, mouse, speakers, printer), restarting is not going to do anything. In some cases, it may actually hurt your computer (if something went wrong and it won’t reboot).
So before you reboot, I implore you to: GOOGLE IT.
Seriously. Google the problem and look for an answer. It will probably take you less time to fix than waiting for your computer to restart, which could take a looong time if your computer is more than a few years old.
In fairness, you could also “Bing it” if you want to…it just doesn’t sound as cool.
