Order a replacement keyboard online, and replace it yourself.

I got lucky and went into Control Panel and rolled MOUSE driver back to previous version, then rebooted. Works fine.
The clue is that the mouse driver is for a different mouse. Yeah the mouse driver screwed up the keyboard. Go figure?

@boatmany: Don't know how you figured that out but glad you did. Worked for me.
