Unable to use my mouse

I cant see my mouse pointer, When i launch the game i cant use my mouse pointer, I am unable to navigate the menu (it sorta works with WASD keys but its limited) When i finally manage to join a server, i am unable to aim at all, If u ucheck the Raw mouse input setting i can move/aim but the speed i faster than sonic. Changing the sensitivity doesnt do anything at all, And when i start aiming left the aim goes right at first then up and eventually to the left(same if i try to aim right) Is there anyway to fix this issue at all or am i screwd?
