Resolution/Fix:

Desktops:

If the computer is a desktop, turn off the computer and reseat the graphics card.

If the issues continues after reseating the card you should try replacing the graphics card with a new one.

Laptops:

If the computer is a laptop try connecting an external display to the system to see if you get video on it.
If your laptop gets video on the external monitor, check the internal connection between the laptop display and the motherboard.

If that connection is good, you most likely will need to replace the built-in LCD panel or the display inverter. Both are normally sold together.
