mailpup said:The thing about a system restore is that you can undo the restore if it doesn't produce the desired results. If the problem didn't occur too long ago, you could try it.
Alternately, you could buy another keyboard to try it. I know it seems wasteful but you only need to buy an inexpensive one. Many cost less than $10 ($6-$8). Of course, that doesn't include shipping or tax, if any. Take a look at Newegg.com (Click here) for some choices. It's up to you, of course.
