Outside "Entertainment Center" 120v Outlet Issue

There isn't another GFI outlet that I've been able to find. I even checked the refer outlet to make sure that wasn't the problem - no reset button there. We did have a bunch of stuff plugged into the outlet when it failed - crock pot, Dish tuner, tv, etc. My first thought was that we had overloaded it, but I can't figure out where another reset button would be.
