Take your battery out and try to reset your bios battery as well on the mainboard. When you did that don't plug the main battery back but use external power first to see what will happen. If this will not fix your issue then you have a hardware problem (GPU/Mainboard).
You didn't mention what type of a laptop you have is it an HP? h t t p://w w w.youtube.com/watch?v=PhxOVh2sbl8
