Hi Danyel,
I don't know why this is such a complex question... it looks pretty simple to me.
"She said..." <-- and that's all you need to know. You treat reported speech as as "true at the time you heard it", so everything goes into the past, even if it is true now.
Exceptions which move into the present are very, very rare. If you're ever not sure... just drop it into the past. You can't go wrong.
Typically, the phrase would be, "She said that her computer was broken." (ie. "My computer is broken," she said.)
