My son has major OCD computer rituals. Sometimes it takes him an hour to start a game because it has to start in a certain sequence, and if he's not sure he did the sequence, he starts over. He can spend hours and hours running virus software over and over when he's really having a difficult day. It takes him days to think of a new username or game name. He can't make up his mind and OCDs about what they mean, etc. I really don't know the full extent of how he's OCDing on there. Those are just the few things I know.
