NP9130 Keyboard Issues

Hi everyone! I've had the Sager NP9130 for about 2 years now and I love it, but recently I've had a problem with the keyboard. Specifically, the control keys don't work. The key seemed to sort of "go out" over the course of a week, and now completely doesn't work. I took the key off and looked at the board and it looked fine, I even blew some compressed air in for safe measure, it didn't help. The weird thing is, I uninstalled my keyboard driver and reinstalled it and it was fixed for about a day and then started to go out again. I'm guessing that means it's some sort of software issue, but I can't imagine what else I can do aside from reinstalling the driver again, which seems like a band-aid solution at best.

Anybody else have this problem, or something similar? Any ideas on how to fix this?

Weirdly enough it's working right now but wasn't this morning, both keys seem to go out at the same time.

 

The driver for the keyboard is typically a native one to Windows (it's recognized as a generic PS/2 keyboard), so reinstalling the driver and having the key(s) work was probably coincidental. It sounds more like a hardware issue. If it's only specific keys, chances are that those circuits on the key matrix are faulty and not registering keystrokes, therefore no data signal is being sent. You'd have to replace the entire keyboard, if that's the case.
