Question

laptops

Good afternoon, readers!
Here's what the problem looks like:
https://youtu.be/U7nnEGIvs3E
These interferences permanently block the laptop until it is completely turned off. The problem appears without any periodicity. I tested the video core through firmark and aida (as well as memory), I cleaned the contacts at the screen cable (but did not change it). Notebook model ASUS X507MA-EJ012.
I do not know what to do. Tell me, please, who faced this, what is the problem and how to solve it? Thank you in advance!
