Colorful stripes appeared when I started my laptop. I tried to restart, but the problem remained. Maybe there's a problem with the graphics card. What should I do?
Just paint the colored stripes in black and you won't have the problem anymore.
Colorful stripes on the screen: The cable to the screen is probably over or there's probably a hardware damage. I suspect hardware errors.
I also had it. This continued to propagate until half the screen was "colorful".
