Unexplained Phenomenon

Okay, lets see what you guys think:

PC: Dell XPS 400
OS: Windows 7

The issue with networking that I am having is really weird, the computer in question here was at my grandparents house, plugged up to their network and working just fine. I unplug it from there, take it to another house and plug it back up (All but the internet [ which is windstream / SpeedStream modem.]) I reformat the computer, THEN i plug in the internet cable, update the machine, all that good stuff. I walk out of the room and when i come back, the modems DSL light is blinking.

So after ALOT of basic trouble shooting, I figure it is my computer (The computer I am typeing this on IS ON that same router so I know it works.) Now at first i thought it was my network card(s). I put the (s) cause it has one that is built onto the motherboard, the other plugs into the PCI slot. The on-board isnt being used because the clip that holds the cord in is broken, so ive been using the other one since for ever.

I then rulled that out cause I ALSO plug in a USB cable from the modem to the computer, installed the drivers and all that good stuff also, AND still it doesnt work.

Any more information needed, jst ask.
