My computer was working fine, But when I tried to write a message back to a friend on facebook, Every time I made a Key Stroke I would hear a clicking sound come from my computer and nothing would be typed on my computer, I have tried everything I could think of to fix this problem but nothing has worked, When I hold down the Key after it clicks a second time it will type the letter out on the screen, But I can not write messages like that, it would take me an hour just to right a few words, I am using Windows 8.1 Pro.
This may happen if Filter Keys are on.
Open Control Panel > Ease of Access\Ease of Access Center > Make the keyboard easier to use
Here scroll down to “Turn on Filter Keys” option
De-select “Turn on Filter Keys”
Select the “Apply” button and “OK”
