When I press down on left ctrl i cant use a. If I push them too fast together it does have the chance of sticking the a key which I would need to double-tap to fix. It makes gaming harder and im not sure why it does this ive never had this problem before. I play stuff like csgo and overwatch and I just want to be able to crouch while moving left again. The keyboard I have is also fairly new.

Edit: pushing down on left ctrl does not affect my other keys just a it seems.

Edit 2 9/12/19: Tried another keyboard. The problem seems to be from my computer. Not sure what is conflicting with my keys though. Does anyone have any ideas what might be messing with how my left ctrl and A key are working together?
