    Kindly try the following a clean re-installation;

    - Uninstall completely the existing keyboard drivers and restart your PC.
    - For this part, use the built-in on screen keyboard or connect an external keyboard for the mean time, next go to the manufacturer's website of your laptop, which can be found here. LINK:
    - Search for the appropriate keyboard driver for your Dell unit.
    - Once done installing, restart your PC once more. This should fix your keyboard.

    5) Select “Let me pick from a list of device drivers on my computer”.
    6) Select the driver option according your device model and installed.
    7) If this does not work, follow the steps from ‘1’ to ‘3’ and select “Search automatically for the updated driver”.
    8) Choose the same steps to update the driver for keyboard as well.
