anyone know what the big Question mark is ?? is someone attached to my computer? I dont have a router, just a dsl modem

Wouldn't think to much of it. Windows does a crappy job of putting these drawings together. Can you get any more information out of it (right mouse click or something?). Your dsl modem probably doubles as a router.

Could you post a ipconfig /all?
