Recently had a new hard drive fitted, and after installing keyboard the @ and " have been reversed, as in pressing @ on the keyboard results in " being printed and the same the other way. Any kind person out there can give me a clue to rectify this problem.

Go into your control panel and go to clock region and panel and them from there you can change your key board to where in the world you are

Glad it worked took me ages to figure that out when it happened to me
