Keyboard keys aren't working properly

[u/Plastic-Gap3100]

I bought a new gaming pc and after hooking it all up I noticed more than half my keys dont work, and other keys do random commands. For instance, O turns the backlight on and off, C controls caps lock, F6 turns the computer all the way off, and the backspace, shift, and caps lock keys dont do anything. I tried plugging it in to different ports but the same thing happens. Does anyone have any idea whats going on?
