Today I got back to my PC after eating and then the buttons where a little weird so I tried to restart my computer but nothing changed they're totally messed up:
Q and S = Windows Explorer
W, U and O = W
E, T, Y, Å, G, Ø, V and M = Nothing
R and Z = Windows Media Player
I, A, K and C = K
P, X and N = X
D, J, L and B = L
F and H = H
Æ = Go to page (When on Opera)

And that's just the alphabetic keys all other keys are messed up too inclusive the buttons on the mouse. My keyboard is Razer Arctosa and my mouse is Cyborg R.A.T. 3
