Even without load at the +5V rail the +12V regulator has to provide 
current for loading the capacitors of the +5V-supply. This effect may 
become even worse, if some modules have +5V regulators on board, which 
use the 12V for supply.

So, my first try would be: remove the +5V supply from the +12V rail.
