so I'm having a problem with my pc -> after using fire fox about an hour my browser does not load and then I get the cannot find... message and I open up IE and that cannot connect connect on that either. I lose my Xfire and AIM connection and have to restart to get connectivity back - its doing this even after I have updated my network driver for my MB. I have Microsoft's new spyware beta tool running all the time and that is the only big change that I can think of that has happened in the last couple of days - no viruses and spyware on the system after searching. ANY HELP?
