Wii U won't load any apps or games

-
Hello,
I am having troubles with my Wii U.
When i try to open any app on the home screen (even settings) the music stops and it completely feezes on the load screen. Did any of you have a same problem or do you know how to fix it.
Help would be much appreciated.
