lol, funny how people didn't try to help or they are so low on knowledge. He clearly doesn't have installed his GPU drivers.
@Physco, (in case your problem isn't solved yet) If you got a branded PC by any brand, you can go to their site and search for you PC's model and you will get all of your drivers there. Just download GPU ones. Or the other thing you can do is contact me when you are up, I can help via team viewer.
