Usar: Se me ha...
¿Cuándo y por qué se usa la construcción 'se me ha [participio]'?
Por ejemplo: ¿Cuál es la diferencia entre 'he olvidado' y 'se me ha olvidado'?
Otros ejemplos:
Se me ha colgado el ordenador. (I think this is: My computer has crashed (on me))
Se me ha ido el santo al cielo. (An expression: I forgot was I was going to do/say)
No entiendo el uso de los 2 pronombres. No creo que uno sea el complemento directo y otro sea el complemento indirecto, pero no lo sé. Estoy confundido.

It is a matter of perspective. What is the difference between "The glass is on top of the coaster" and "The coaster is under the glass"? Which one is the right one? When should I use one or the other? Why do you have two ways of saying the same thing? Can you define exactly what does each one mean? [... and more questions like this]
In "He olvidado" YOU are the person executing the verb -YOU are the one who forgot, YOU are the subject and direct responsible for it. "Olvidarse" means that things leave your memory, and "me" is an indirect object, which is used to indicate who gets affected by the outcome of the verb. See? You no longer do things -things are done on you. Can you imagine what the difference is? (go back to the glass and the coaster, if you are not sure) Yes, both mean "to forget", but they do not sound the same.
Se me ha ido el santo al cielo. (An expression: I forgot was I was going to do/say)
Same thing again: the "concentration" goes away to the sky (this is a metaphor), and "me" indicates who has been affected by this loss of concentration.
The closest thing you've got in English is the indirect "It appears to me that..." instead of a direct "I think that..."
I would only add that by adding the "things are done on you" flavor, you add the nuance of "my bad" or "I blew it." Something was at stake and this thing that has been done on you prevents you from coming through. The computer didn't just crash. It crashed on you while you were trying to get something done. It's not just that you don't remember, it's that the thing on the tip of your tongue is gone and you can't deliver the info.
