Hi Mert Beran
Welcome to the Toms Forums, sorry its an error that brings you. it works at password screen? that sounds like a software error and the surest way I know to verify that is to try it in a different envorinment, like linux.
Boot to a USB drive with linux on it. grab a USB drive, a copy of rufus and a linux distribution.
http://distrowatch.com/ has tons of differing linux distributions and download links. I personally am fond of linux mint with cinnamon.
https://rufus.ie/ the utility used to extract the ISO file to the USB drive.

use rufus to extract the selected ISO to the thumb drive. it will make the drive bootable and you can run linux from the drive once done.
Reboot into linux and proceed to test the hardware. connect to internet, watch videos, await problems.
if linux is good and stable the issue is most likely inside windows or otherwise software related.
this is a test of the hardware.

boot to the drive and see how linux treats the keyboard. alternately you could move the keyboard to another device and test all the keys. laptop, tablet, anything with the right port.

if the keyboard checks out it HAS to be an issue in the software residing in windows, a driver conflict, something is disabling the keyboard after login.
