Wtf is going on with my PC?

I can't log onto any page but Eden (using Firefox), can log on AIM but I can't send IMs to anyone, XBOX works fine online... help... ;[ (Oh and laptop is connected to the same network wirelessly and it's doing fine)

First guess is something wrong with DNS setting on your laptop.

Open up the command prompt (Start Button, Run, type in cmd)

Type in the command "ping www.yahoo.com" and if you get a response time out, try "ping 145.253.253.226". If you get a response, then its DNS for sure.
