Objects jumping around indoors

[peppergomez]

I noticed in Riverwood when I went into both the Inn and the merchant shops that there was a load continuous rumbling sound. At some point I noticed that some of the objects seem a bit jumpy, with a few swords being knocked across the room when I approached them. 

 

This movement doesn't happen that often, but the rumbling sound does.

 

Does anyone know what might be causing this?

You didn't happen to install the earthquake mod did you? Other than that make sure your fps is capped at 60, i.e. vsync on.
