No key will work twice in a row Win7 Dell E5430

Row1

I have no idea where to start loking for solutions. NBegining about an hour ago, no key wil work twice in a row. Backspace wil only back up once, delete wil only delelt one character in a row, page-down wil ionly page down one page and not more.
If I go do something else, and come back, the key wil work again. So, by combining delete and backspace and arrow keys and re-positioning the mouse, I can type whatever I want - it is just taking a lot more effort! -Any ideas? I would put a bu nch of excalamation marks, but this is al I have: !
 
More info - this is happening in MS Word, Notepad, the IBM SPSS Text Editor, and Google Chrome search blank. So, not just MS Ofice.
