Partial keyboard working

[aqeel96]

Hi, I am having a hilarious problem with my laptop keyboard. My laptop is  HP Notebook - 15-ay138cl.

I am facing keyboard issues for 2 days. All the keys are working separately but some combination of Shifts are not working. For example, when I press Shift + 2 which is @ (not wokring) whereas the "2" key and Shift key are working. I am able to type type large alphabets using Shift and some combinational keys also works using Shift but some of the combinations are not working. I tried may online softwares and Hp keyboard checker, all the keys are fine and they are being detected successfully.

External keyboard is working fine. When i tried from external keyboard, holding "Shift" from one keyboard and "2" from other keyboard type "@" in both cases ( both combination with internal and external). 

Can any computer geek help me on this ?

What is the issue , is it the problem with Windows? What should I do? Should I re-install windows ?

I tried every second thing from the internet. All the keys are working even with HEFI diagnosis tool by HP.

Reinstalling the windows and keeping the driver to old versions fix the issue. This issue was due to the fact that drivers of touch pad and keyboard got updated automatically via windows update and it creates problem.
