blackwidow v3 mini hyperspeed not working

i recently started to have some problems with my blackwidow v3, the keys dont work they basically dont register when i press them or the keyboard will register them twice. And that has made gaming or typing pretty much impossible. I have tried everything to solve this problem, like updating to the latest drivers, factory resseting even deeply cleaning the keyboard and the problem still wont go away. i hope it can be fixed and if anyone has o had any similar problems and were able to solve i would aprecciate very much your help.
