My computer has error messages and shuts off?

Lisa points out her discoveries to Homer and Marge, but Lisa's parents dismiss her accusations as sibling rivalry. The events come to a head when Party Posse perform a concert on an aircraft carrier, which only increases Lisa's suspicion towards the band. During the first song (which also contains subliminal messages), L.T. learns from his superior officer that MAD Magazine's next issue will reveal Party Posse's secrets, which, until then, had been kept secret from the public. Concerned the magazine will end Project Boy Band, L.T.'s superior officer shuts off the band's voice enhancer, exposing the groups's mediocre voices. LT. becomes increasingly aggravated about his Superior Officers's actions, and threatens to send the carrier out to sea. When L.T.'s completes his threat, a terrified audience evacuate the carrier. With only Party Posse, L.T., and Homer on the ship (Homer was unfortunately in the toilet at the time), L.T. sends the ship to New York City in an attempt to attack MAD. Despite 'N Sync's attempt to stop L.T., he destroys the MAD building with the ship's missiles, but L.T.'s actions appear to only reinvigorate the MAD workers. After L.T.'s criminal actions, he is arrested, and the potential of the fraudulent Party Posse remains unfufilled.
