System software issue or something

A crazy software issue has come up. It's been around 10 months since the wii u was turned on at all. Now that we have, it boots up fine and you can log in to a nnid, but when you try to access any of the apps on the top screen (disc game, downloaded game, even system settings), it shows the app icon in the middle of screen and plays some transition music, but never gets further and the music goes quiet after about 15 seconds.
