So I recently built a computer and installed Vista Business Edition as my OS. Everything is working great, and I'm really happy about this PC. For some reason though, a lot of webpages aren't working. I am not sure what the problem is, but I'm having trouble surfing the web. I'm using IE7, but I tried using FireFox as well to make sure it wasn't IE's problem. When I try to visit a lot of websites I get "Internet Explorer cannot display the webpage. Most likely causes: You are not connected to the Internet. The website is encountering problems. There might be a typing error in the address. " I am not sure what the problem is, and when I try to diagnose this it says that it may be a problem with my ISP, but its definately not because my other computer visits these sites just fine. Does anyone know what this could possibly be? Thanks!
