Ok well I was playing ZombiU (class game) and my WiiU froze.
I did a reset and when it started to load it made a weird grind/pop noise and wouldnt start up!!!!!! 
My gamepad turns on but is just a white screen!
I will be returning to the store I bought it from tomorrow but I know they have no stock and wont until xmas at least.
I will only get store credit also as I traded stuff in when buying 
Not sure what ill do tbh but I might now hold off on the WiiU until next year
Enjoy your consoles guys and gals!
that can't be normal.
