It doesn't matter how much you want to continue riding beating a dead horse is not going to get you anywhere.

If something is already done and over with there is no point in still talking about it.

If something is already broken there is no point in trying to use it.
Someone breaks up with there girl/boyfriend and continues to bitch about them to there friends weeks later. That person is beating a dead horse, the relationship is over there is no point in thinking about it since the matter is already resolved with you having broken up.

Relationship = dead horse
Bitching about it = beating it

Trying over and over to start your car after you've been in an accident where it is clear that the car is not going to work.

Broken Car = dead horse
Trying to start it = beating it

An instance in which the "beater" of the horse will continue to try and make amusing comments until either
A.) Somebody makes a "pity laugh" (this is usually the person who originally told the joke) or:
B.) Everyone leaves.

This is a common occurrence when a moderately funny person loses their game, and is convinced that they are not off of their game.
The perfect example of beat the dead horse.
