Need to unplug keyboard

About 6 months ago I had to start using a USB keyboard as the on board had basically stopped working. I just plugged in and a keyboard and have used it like I said about 6 months.

But in the last week or so I have had a new problem show up. Any time I start typing, I have various and random menu's open (start setting {or sub-menu} or context possibly others I don't remember)  in the beginning it was just annoying, but now sometimes it's every 1 or 2 letters. Then there will be anywhere from 1 to 6 menus open at once, close all that, hit two letters, and close all again.

So if I could get a picture with one of those red arrows, I would appreciate it.
