I'm using TPG on winXP and whenever I connect to the net, it works fine for the first 5 to 10 minutes. But after that the internet freezes. The computer doesn't freeze but all net applications don't work. If I try any website, it won't load. If I am downloading, it stops. If I have msn on, it disconnects. All this happens with the computer running normally and the modem hasn't disconnected.
What is going on?

Check for Virus and also empty the contents of temproray internet file folder and temp folder in doc. And settings folder

I have the same problem,the pc's functions run smooth but the internet freezes and I have to reboot. I just reinstaled my windows xp sp3 and it still does that. Can anyone help?
