Its Not My screenshot but i have the same problem (sorry if this screenshot is stolen) My Gpu Is A GigaByte AMD RADEON HD5750
Could be: Broken drivers (I doubt. Anyway reinstall would help) Unstable overclock Broken/Faulty hardware
As far it supports DirectX11 (or DirectX10.1 for compatibility mode), it would work. That pretty much hints toward a faulty hardware, I've had the same in the past in other games.
