Do you have any plugged in but unused controllers lying around? The only time I've seen this, it's usually a controller I think is disconnected or inactive, but is actually connected & lying such that it's L-stick is being pushed - we haven't seen it just do that otherwise without any apparent reason.
Aside from that, do you notice anything odd with the mouse cursor, or other input? if you try to override menu selections with the mouse (timing it to select choices quickly before it advances), do you notice anything else odd the further you make it into the menus or gameplay?
