HeroBook Pro flashing screen in various colours

Laptops
#1

Hi all,
I bought a laptop back in October this year and I was happy with it. However, something has happened to it and I am trying to find out what. After working for about 2-3 min the laptop’s screen is starting flashing in green, red, white, blue, and black colors. Can you please give an advise on what it could be wrong?

Many thanks

Before assuming that it may be a hardware problem, we must rule out that it is a driver problem, so you should try, from the device manager, go to the screen and click with the right button of the mouse, properties, controller tab and there see if you can click to return to the previous controller.
