I don't know if you have done anything lately,ie; updates to board, cahnge of cables, etc. but first, try shutting down system, unplug your cable for video, unplug tour tower, plug tower back in and restart. If this doesn't work. You may want to try a system restore back to when you had a picture. Try this and let me know if this worked by adding comment or reply at the end of solution.
