Well right there I can see your on a 4 second shutter speed 4". what you do is move the dial that controls shutter speed till it get to something like 1/250 or more, it either the front or back dial on the upper right of the camera, it depends on your configuration but just go by what moves on the the LCD. Does that improve things.
FYI leave ISO for now. Nothing is broken with it you have just put in the wrong setting for the desired use.
