As I mentioned, it could be your NVIDIA driver version. Try a version or 2 above or below the current version and see what they do.
We would also recommend you use a GPU with at least 2GB of VRAM for HD workflows. But I doubt that is what is causing this particular issue, but maybe. Seems more likely to be the NVIDIA driver.
