So, I booted up Solaris [a UNIX-based OS] on an old desktop I had and used my keyboard on it for a while. Once I was done, I plugged the keyboard back into my main system running Windows, and all of a sudden, certain keys weren't working. [Insert, Delete, DwnArrw, and the first and third row of the number pad, to be exact.] I've since tried reinstalling the drivers and even using the board on a Linux system, but nothing seems to make it work how it did before. I know for a fact that it is hardware related. Did some sort of layout change happen within the keyboard itself? I'm using an Intel Wireless Series Keyboard that connects to a USB Base Station. I'm really at a loss here, so any help is greatly appreciated.
