When computer starts it gets horizontal white lines scattered across the screen. It'll go away but it always comes back, even while it's working properly. https://youtu.be/ddXE53ELvlk

i will say the graphics card is faulty. Have seen something like this happening to a friend and found out that the GPU was faulty. You should check with another GPU , like maybe a friends GPU to be sure.
