I think my PSU (HP computer) has blown?

no whats happend is your power pack inside your pc has had it you need a new one but dont replace it yourself make sure you have someone that knows what there doing otherwise you will have a destroyed pc as for the shuting down there could be dust in the fan causing it to slow down wich means the pc will overheat and shut down automaticly (usualy about 80 -90 degreas)
