Keyboard issues

[xMr Fister]

Hi guys!

 

All of a sudden my Corsair K70 LUX RGB keyboard isn't reacting on the following keys:

Capslock, Numlock, F keys, arrow keys.

 

I have tried to do the following:

go into safe mode- all keys worked fine and as it should.

Hard reset the keyboard- didn't help

reinstall the latest bios- didn't work

uninstall iCue- didn't work.

go into device manager- uninstalled all keyboard drivers and restart- didn't work

 

Thanks!
