I run Win10 32 bit and Razer Blackwidow keyboard. I recently had a meltdown of Win10 and I had to reinstall Windows and all of my programs. Following this, I had the following problem with my keyboard. When I hit the symbol @ on the keyboard, the symbol " is displayed. When I hit the symbol " on the keyboard, the symbol @ is displayed. I have tried using a different keyboard but with the same result.
