Windows – Some of the keys are automatically being pressed along with other keys

History

The last time when my computer shutdown was a power failure. Now some keys are automatically being pressed when I type something.

The last thing I did to keyboard setting was adding a keyboard layout (on Ubuntu).

What is happening

Whenever I press c, xc is writeen

s gives me sd
d gives me sd

e gives me we

2 gives me 23, So when I want @ it gives me @#
3 gives me 23

Pressing CAPS Lock gives me F3 and vice-versa.

All other key are either working fine or I don't use them.

I have two operating system Ubuntu and Windows, I use Windows very less and found this problem on Ubuntu, but as soon as I logged in to Windows (for checking) then I found that Windows has the same problem.

Effects on my life

• This starts form the time of login, even I have problem in typing my password.
• Whenever I try to save any webpage, it is bookmarked automatically.
• Whenever I copy, it is cut automatically.
• I have to spend more than half of time correcting what I have typed.

Note: Typing thisd quwesdtion wasd rweally a big pain to mwe.
