A scene I made is not rendering, at all.
Here are my settings:
(please follow the links in blue for further details)
Object has been disabled for rendering
The Eye icon is to toggle object visibility on the 3D viewport.
The Arrow Icon toggles selectability.
The Camera Icon toggles Rendering.
There are no lights in scene.
To Fix add some lights.
Lights are set at 0 power. To fix change the values to a higher number.
Lights have been disabled for rendering. Enable the camera icon in outliner window.
Strips on the VSE
There are strips present in VSE and the Sequencer box enabled in Post-Processing. The VSE takes precedence over scene rendering. To fix clear the strips on the VSE or disable the Sequencer box.
Object or camera are in a different render layer
To fix include the layer where the objects are as part of the render layers
To understand how layers work read: Can someone explain the layer system?
Camera is blocked.
Is the camera behind a wall or another object?
Note that an object in front of the camera might be restricted from viewport display, making the issue not apparent in the viewport or render preview.
Camera is set incorrectly
The rendered image is that of the active camera's view. Not necessarily the view you have active in the 3d vieport. Press Numpad 0 to show camera view.
Active camera is aiming in a different direction.
Wrong Camera being rendered.
You can have multiple cameras in the scene, but only one can be set as the active camera for rendering. Check that you are using the correct one.
In the properties window you can determine which camera is the active one
Or select the camera you want to make active in the viewport and press Ctrl+Numpad 0 to select the active camera.
Object as Camera
An object in the scene has been set as camera. Set the camera back to the active camera. To fix select the camera to be used as active camera.
Output node disconnected
Output node in compositor might be disconnected. The composite node is the final output (not the viewer node).
Film exposure is set to 0 (Cycles) Unless you have a good reason to change it. This should be set at 1.
Make sure that you set the clip start and clip end so that the camera can see within a distance range that encompasses the scene. Geometry that is too close or further away than the set parameters will not render.
If your scene is too large or too small, if the scene is not within the range defined by the clip distance, then the camera will not "see the scene". Enable Display Limits on the camera to visualize the clip range.
The scene is completely out of focus (blurry)
Focus for the camera set to 0 and lens aperture (f-stop) is set to a low value.
The scene is so out of focus that you only see gray or some color that is predominant in the scene.
To fix, change the distance value to the actual distance form the camera to your object, and maybe try a higher number for the f-stop.
To find where your camera is focusing you can enable display->Limits. If you move the focus you'll see a cross mark that indicates where the focus point is:
A trick you can do is use an empty. Move the empty to the place you want the camera to focus on and select the empty (or any other object as the focus target).

Restarting my computer did the trick. Was probably a RAM issue.
This was happening to me and I had previously post processed an image and noticed the console mentioning post processing before the render would stop after 32 seconds. I turned off post processing in the render settings and my render would work again. Hope this helps
aha.....tracked it down to the fact that when I was messing about with the mist with the compositor nodes I had left the use nodes and back drop buttons selected .....as there was no longer anything to 'composite' there was no longer anything to output I presume.....anyway sorted now. Another 3 hours of misery lol.
Additionally I found that the focus needs to be set to a specific object in the depth of field pane. If no object is set, you will get a blank screen
