Welcome to the forums, geppers2.
I know this sounds simple but are you sure you actually have a connection established to the internet?
If you are using dial-up or cable modem, are you sure the connections to your computer are not loose?
If you are using a wireless connection, are you sure the computer's wireless card & the wireless modem are working correctly?
With all you have "turned off" there should be very few reasons why you cannot access the internet.
