Problem with a keyboard

[Edvardas]

Hello. I have a problem with a keyboard.

When I press number 6 button (one above the letters), it registers as stuck and does this - 666666666666666666666666666666666666666666666666666666666...
It stops the moment I press any other button.
This also happens the moment I turn on my PC. In the password place it just spams number 6.

Physically the button is not stuck, I cleaned my keyboard a bunch of times.

Do you know any solution for this problem?

You will probably have to replace that keyboard. What make and model is it ?

At this point we don't know if you are talking about a desktop or a laptop computer.
Desktop is easy: swap out the keyboard
Laptop, if you can't login because the "6" key appears to be stuck when it it not, then in order to use the laptop, you'll need to replace the keyboard.
If it only acted up once in a while, you could try the onscreen keyboard.
