When you turn on your Xbox 360, it makes a buzzing noise. It’s not a bad noise, but it’s not the best sound in the world. Some people think it’s because of the fan in the console, but that’s not really it. The noise is coming from inside the console itself. The problem is that this noise is coming from a small part of the console that’s called the power supply. The power supply is responsible for turning on your Xbox 360 and providing power to all of its components. It also helps keep your Xbox 360 cool and running properly. But sometimes something goes wrong with the power supply. This can happen when it doesn’t have enough juice to keep your Xbox 360 running properly or when it starts making weird noises. In either case, you can’t use your Xbox 360 anymore and you have to take it to a store or get help from someone who knows about Xbox360s.
