ie/firefox stopped working while network is on

hi,guys:
here is my situation.
I am using xp os. several days ago, my IE/firefox stopped working. However, I can still use my outlook and bittorrent to download movie. I checked my network setting nothing wrong to me at least. another pc using the same router works fine.
another interesting thing is that after reboot my pc, IE/Firefox works for a few minutes and then error message popup. IE: check your lan setting,etc. firefox: the server was reset while firefox was trying to connect something like that.
any idea?
by the way, I even tried to repair install xp , norton scanning which did not help either.
