CTRL key doesn't work, Windows 8.1

A while ago i cleaned out my keyboard. Later after that, both my CTRL keys don't work properly, and the button to turn wireless off and on does not glow blue. When trying to copy something, Right CTRL+V just prints out L;j. Pressing it in general turns the volume up or down. It makes generally hard to play games and i have to rebind crouch in all my games.

Your specs say PC/Desktop but Keyboard says Built-in HP Keyboard. I don't understand, can you explain more please?

Have you tried another keyboard (external if necessary)?
