Is your network card enabled and properly configured? Do you get an IP address from your router? Can you ping your router? Can you ping

My situation is similar. I did a factory restore though. I went a head and allowed my computer to do windows updates and then I promptly download MSS Essentials. I went to the MS window themes and downloaded a few of those.

Then I went looking for up to date drivers for my Dell. That's when I started getting this message that says "unable to open this site. The site is either unavailable or cannot be found."

I get this message for Dell's main site and Microsoft. Also I see this message for Google Chrome.

btw none of my video files are playing. I don't know if that is related.

Have you tried using Windows Repair?
