answer:First off, have you called Microsoft? I’ve had friends get their boxes replaced. Its worth a shot. The best way would be to take it apart. That’s really the only way you will get all the dust out. Ideally I like to clean out my computers with compressed air twice a year, so its a good idea. If you don’t want to take it apart, I would just stick a vacuum nozzle on the vents and try to suck the dust out. Trying to blow it out with compressed air would just succeed in burying whatever is in there deeper.
