Try installing the GPU card in another computer. If the exact same thing happens it is possible your GPU card got damaged from overheating or the Cowl (heatsink and fan) cover is not making good contact with the GPU chip.

Use integrated graphics or a cheap GPU card and see if you get video. Got this from this website : Symptoms of a Faulty Graphics Card and How to Fix Them - Make Tech Easier

Try installing a older AMD Driver and see if Windows recognized the GPU Card.
