What's up with the DCC system you've got? Are you certain there's no bad connection of even a short circuit somewhere that 'snuck' in while laying your track and wiring things up? Check if all frogs are clean and have no bits of 'junk' wedged in, and if you use Peco 'electrofrog' turn outs, make sure that the two rails leading up to the frog point have insulated rail joiners installed.. There may be other brands of turnouts that need the same treatment, but it's easily overlooked.
