April showers bring... STORMS
Storms are a fact of life. Stormy weather commonly bring power interruptions, which bring irregular power to your computers. Most people don't know that when the power goes out / comes back on, there is minor power spike usually associated with it. That's where power protection devices come in.
Power protection devices for the home commonly fall under 2 categories - Surge Protectors and UPS. These devices are designed to take that excess voltage and redirect it to ground instead of it going into your computer and possibly damaging it.
