It seems to me the expression emanates from "hung up" — as in a telephone. I think the expressions (1) "to leave hanging" as in "Joe Sixpack just left me hanging at the bar" and "to hang around" come from the same terminology (Ma Bell has left us with quite a few words). Hang variations all seem to show the same result of idle time. However, if you ask a teenager what he's doing and he's just hanging out it could mean that a) he's having a thrilling time at the amusement park, b) he's stoned and lounging in his bedroom, c) he's mowing the lawn, or whatever.

You probably have thought of all this.

I would say:

My computer crashed. (Ha!)

or maybe:

My computer froze [up (on me)].
My computer left me hanging.
My computer hung (on me).

or in your case:

My computer is trashed on the sidewalk below.

I think the crash event is like the word snow in Eskimo.
