about 2 weeks ago I was awakened by my father (I just passed the session could sleep) with horrible screams, he says that he broke the fan and said I must urgently go to repair it.Well, I asked him roughly replied that I am a programmer and not a technician, he did not talk to me for 2 weeks, today tomorrow again calls says-"Son, sorry, I confused the fan with a rough disk, come repair please"and what to do with them?)
