HELP Please: problems connecting to Google Chrome or Internet Explorer: think it has to do with my network cards

My computer works perfectly except that I can't connect to the internet using Google Chrome or Internet Explorer. Internet works fine.  I have another computer that is connected to the same network, and it works fine.  Also my signal strength is optimal. When I try to go on Google Chrome, it says that the web page is unavailable & the reason why is error: 105 (net: ERR_NAME__NOT_RESOLVE) the server is not found.  When I try to use the Internet, I get this message:

Device is not working properly because Windows cannot load the drivers required for this device (Code 31)
I've tried everything and looked at other forums. I went into Device Manager and tried to update the driver, but whenever I do it just says that all updates are already made.
I really feel that my problem has something to do with network cards. When I go to Device Manager and discovered the network adapters 13 different adapters appear. The 1st is Atheros AR5007 802. 11b / g Wireless Adapter and it looks like it works very well but there are 11 different (Microsoft 6to4 adapt #10) (all have different # s, 10,11,12,14,15,16,17,18,20,5,9) there is (NVIDIA nForce Networking Controller)
I think the problem is with the Microsoft 6to4 adapters because win I right click & then click on PROPERTIES of each adapter says: State of the device, this device is not working properly because windows cannot load the drivers required for this device. (Code 31) So, is to "find solutions", says & when I do that nothing happens, a message flashes on the screen that says: "Could not load driver software" and that windows is looking for information, but nothing ever happens.
Can some1 please help me! My computer worked fine and both Google Chrome and still worked and then out of the blue it just stoped working. Any information would be very useful

wisports,
Thank you for visiting the Microsoft Answers community forum.

You have found the source of your problems.  You must remove or uninstall, all the cards of 6to4.  Also delete everything that said map Tunnel or card miniport WUN.  Also uninstall or disable, Internet Protocol version 6 (TCP/IPv6) Properties tab on existing network cards.

Once you have done these things, restart the computer and make sure that the 6to4 adapters does not return.

Let us know how it works for you.
Thank you
