Laptop KB gone bonkers

I have had this strange issue with my laptop keyboard since last week.

Everytime i press any of the numpad keys, the keyboard puts the mouse in highlight mode.
If for example I press the numbers 7 and 9 on my numpad, will input the 7 only and when I move my mouse it highlights everything where I move my mouse.

I have made a video clip of this, if it will make it easier.

Anyone have any idea why it would do this?

If it makes a difference, it is a Dell Inspiron 15 3000 Series laptop.

Thanks
PP

If you have a USB keyboard on hand, check if you get the same behaviour. Then you can rule out (or in) hardware vs windows driver/interaction issue.

Yip, get the same issue with an USB keyboard as well.

If you've installed any new drivers for the keyboard or mouse, roll them back, and if there's any funny software for said keyboard or mouse - uninstall it

Hi

I haven't installed any drivers as of late.
Can't seem to find any suspicious or funny apps/software that rises any red flags either.

Sounds like the shift button making contact when it shouldn`t, might be someone spilled something on it.
If you plug in a USB keyboard, it would still do it because the laptop keyboard is not disabled.
