There might be, but the circuit that your computer is running on might not just encompass your room. As synphul said, too much power might be drawn from the breaker, setting it off. You might have a breaker set to go off at a very low wattage, but that makes little sense. It's either your computer or your breaker, and as long as your computer is built properly, it should be fine, and the breaker has a problem.
