As I say it's impossible to say about the BSOD without more info as there are so many things it could be!

Re the sites, ping one of the affected ones, i.e. google.com

When you do so you should get a reply with a address with four sets of numbers, seperated by a full stop.

What are these numbers (IP address)?

To do so just open up "Command prompt" and type ping domainname.com
