You've only had him for a week, so give him a chance to calm down. Since he is in a new environment, he is going to be nervous and a little scared right now. Has anything changed since you've first gotten him? Can he smell a dog/cat or hear any scary noises?
Make sure he has plenty of exercise... They will start obliterating everything in their cage when they are frustrated.
I'm guessing he is young? Buns under a year should have unlimited access to hay and pellets, so don't take them away anymore! Changing his diet so much is probably stressing him out too.
