You have some service that is still invoking the old sign in information. You will have to methodically go through your services to see which one is doing it.
If you actually created a new account as opposed to changing your ID on your existing one it could be a purchase trying to update, once that was made with a different account.
Check the App Store and iTunes Store to see if there are any updates for apps/purchases. A request for an old Apple ID password is often caused by updates to apps/purchases that were made when using the old ID. One option is to delete the apps/purchases made by the old ID and download them using the new ID if desired.
