Keyboard Malfunction: - Key does bn/-

[Bdgr]

So I spilt some coffee on my keyboard...get over it, it happens.  

This isn't the first spillage for my keyboard and probably not the last (unfortunately).  Everything  is working fine, after some uninstalls and re-installs of the drivers and keyboard software, except for one key.  It's really bothering me.   See, when I press the - key on the number bar, instead of typing "-", it types "bn/-".  Random right? Now, on odd occasion it will actually type -, but it will also do a backspace for some reason.  It's just this one key which is the really annoying thing.  

Are there any solutions within windows or for the BIOS or anything that could help? or even for the specific keyboard?

It's a Gigabyte Aivia Osmium, if that helps.  

I am typing on it now and everything else seems fine, except that - key.  

 

So, to summarize, if there a way to reset a keyboard or something? so maybe the actual circuitry inside the thing resets itself somehow, because I'm guessing that's the problem.

 

(FYI, When I type - in this, it's not because the key is working but because I can use the -/_ key instead.)

 

Also, UK Keyboard layout.

I've spilled water/things (cough) on my keyboard multiple times. I just wait for it to dry and everything's good later.
