Help needed - can only access google + certain other sites. Windows 7/3g Modem issue.

My computer will only connect to google, a few other sites, and this forum. It wont let me on to anything else.

Mostly (for example, when I try connecting to facebook) it gives me this error:

"The server at Welcome to Facebook - Log In, Sign Up or Learn More can't be found because the DNS look-up failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network."

Computer was working fine today, and randomly went on a total schitz and started denying me access to most sites for no apparent reason.

I run Windows 7 Ultimate SP1, the modem is a 3 network 3g mobile broadband USB modem (the black HUAWEI ones). I realise this is a vista forum, but I cant get onto any of the Win7 ones.

Ive already tried a lot of stuff, different browsers, even a system restore and I really need to get this problem resolved ASAP. Can anyone assist please? Would be much appreciated.
