Browsers won't load pages other than Google and Gmail I have a MacBook with OS X 10.6.8 and I am getting "no data received" on Google Chrome, "the connection was reset" on Firefox and "cant open the page" on Safari.

Google search engine works on Chrome and Firefox but nothing on Safari. Scanned the system with my antivirus and found no issues. Cleared the cookies and cache on all browsers and main system with no change. Mac Office did an update prior to this problem but can't seem to get out of this.
Well, you can start the process of elimination. If you are wifi can you switch to ethernet or vice versa? Are the other computers on the same local network able to connect?

Based on my experience, I can guess that hardware is beginning to fail somewhere. A switch, router or your network adapter. Have you rebooted all of those?
