i'd be more concerned in seeing a psychologist than the GR problem

My router gives me shit like that every few months, usualy a nice unpluging fixes that. Your problem might be with a DNS server or some shit, see if other computers are slow on your network. Then if yours is the only slow one i recomend that you open the computer, donkey punch the videocard, and then proceed to golden shower the Ram slots then send it back to apple under warrentee.
