Hello all, Once I start my computer and start working in any application, and lets say half an hour later try to open Mozilla or IE. It gives me a message: resolving msn.com...does something for about two minutes and gives an error message. Both the browsers work absolutely fine, if I keep loding different websites. But if I do not use them for about 15-20 minutes.....I have to restart my machine. Thanks a lot in advance.
