Black bar across top of all photos

I started getting a black bar across all photos that I take with my Nikon D3100. Any idea on what is going on?

Usually a black bar means either a flash sync issue or a shutter problem.

Make sure you're shooting with no flash, and if you get a black bar, it's probably a shutter problem needing repair. Try different speeds. The shutter operates somewhat differently at speeds below 1/250, so a shutter problem may appear differently between high and low speeds.

If you attempt to take a flash picture with a speed above 1/250, you'll get a black bar as well.
