Windows 7: Cannot access most websites or messengers

I moved recently and yesterday got internet installed at the new house, and now most sites and yahoo and aim are not connecting. I can get gmail, this site, sometimes craigslist, msn messenger, skype, and nothing else. No settings have been changed, the only thing new is the new internet. My roommate can access all sites just fine on HIS laptop, so its not a provider issue, its my laptop. Whats going on and how can I fix it?

Hi,

If you are using Internet Explorer; I would suggest you to switch to another browser, like Firefox, Chrome or Safari and let me know if you still face the same issue on other browsers.

If the issue still persists, try running the Network and Internet Troubleshooter by right-clicking the network icon or in the notification area, clicking Troubleshoot problems, and then clicking “InternetConnections”. The Troubleshooter might ask you some questions or reset common settings as it works to fix the problem.

If running the Network and Internet Troubleshooter did not resolve this problem, then I would suggest running Microsoft Fix IT’s from the URL mentioned: http://support.microsoft.com/kb/967897#gm1

Kindly revert and let us know the status.
