White Pixels Flickering on Scree

[grimm1016]

So i bought a Dell Inspiron 15 Gaming 7577 a few months ago and it's been great until recently when I started getting these white pixels flicking all over the screen. It only shows on the laptop monitor and not my external one, any help would be appreciated.

Few months old system, contact Dell for warranty support.
