Lately I have been having a problem with my keyboard: Whenever I press b, b and n are registered. This happens even if I press the membrane of the b key directly (so I know I am not pressing both simultaneously). A Google search did not yield any results so I am asking this here. The OS is Windows 7

However it seems a hardware problem. Plug your keyboard to another computer. Is it happening again? – Jet Apr 29 '14 at 17:18
If you don't have another computer to test with, you can alternatively plug in another keyboard and see if the issue still occurs. I agree that it is most likely a hardware fault. I've had this happen before, but it was due to a liquid spill - never just out of the blue. – MaQleod Apr 29 '14 at 19:28

This is quite possibly due to water damage (a slight drip can even do it). It could also bne dirt bneneath the keys. I would recommend that you:

  • Try the keybnoard with another computer. OR
  • Try another operating system on the same computer.

If you can reproduce the bnehavior in either or bnoth scenarios, you may bne experiencing a short-out (due to water). Or, you could just clean the keyboard using an air duster and see if it doesn't dislodge a crumbn of food which may bne in the way.

Bny the way, I found your question humorous, so I couldn't resist putting in some extra characters so you wouldn't bne alone in your bnothersome probnlem. ;-)
