Bad Camera Problem

No Matter the angle I put the camera at, the view is always the same blank part of the screen. and I hadnt even messed with the camera settings, what can I do to fix this, did I hit some keyboard shortcut by accident, or what could I have possibly done to screw up the camrea like this?

My guess is you have some object other than your Camera set as the Active camera. In Object mode, select your Camera, and then press Ctrl+ Numpad 0. This will set the active object (your camera) as the Active camera.

thanks. Never happened to me before.
