Keyboard isn't working?

So I just built a computer with my brother, everything seems to be working fine except my keyboard (being the Corsair K95 RGB mechanical keyboard) doe

So I just built a computer with my brother, everything seems to be working fine except my keyboard (being the Corsair K95 RGB mechanical keyboard) doesn't work, except for the lights. The keyboard lights up but the keys do not work, and obviously I can't install Windows 10 because I need a keyboard to do so. So I'm basically shit out of luck.
Also, it works on my brothers computer.
I don't know why it isn't working.
Maybe the drivers need to be updated?
Any thoughts?
Thanks!
