keyboard stop work.

Hi all, i'm having problems with bf4, while playing some keys of my keyboard stop work, as example flying with the helicopter the key "a" stop work and i can't turn left.

There is a fix to it ? yeah is happening only in bf4, i got latest drivers for keyboard, vga, and no antivirus or some shit, and i disabled overlay of zlorigin in settings.

TY.

you check keyboard settings in bf?

if u run discord when u play , try stop discord and check , this happened with me 

@PsiMera settings are stock, only difference is the reload with "R". i and can do it with mouse too.

@B7ackhawk okay i will take a look if discord affect me too, cause yeah i use discord while playing.
