Answered previously (If the DVD player works, *try and seek if the player recognises a DVD), then you need to install software to play your DVD. VLC Media player is excellent, free and plays anything.)
I am really sorry to hear that, if you have done all the steps, then I would highly suggest to contact AT&T because they have a system that will just activate your outlook on their end, I believe they will just unblock something on their system then you are good to go.
here for the modem . You will need to select your operation system then go to Software - Solutions > and download HP Connection Manager . If it still does not work you may try to download some of the Driver - Network drivers but i'm not sure which one will work.
I think you have a broken USB keyboard or USB port. Simply plugging in the keyboard should be enough to make it work. First try the keyboard in a different USB port. Test the caps lock to see if the LED goes on and off. Also try a different keyboard and also test it in a different computer.
