I built this PC for a buddy of mine, maybe a year or so ago. He has dial-up. Came up to me maybe a month ago and told me that he cant connect to the web. So he brings it by my house, i plug it in, connects first time. But when he brings it home, it doesnt connect. So i said there was something wrong with the phoneline, but he insisted to get a new modem. So i did, it was a temp fix, now he just called me up and said there entire phone line for the house is shot, im guessing no dial tone. Eather way, they had someone come out to the house to look at it, guy says its the computer. He has SBC phonelines or something of that sort. Is this even posible, if i remember correctly it was a 3m modem, running windows xp.
