Well, ..

If you check another website and it works, how can you still know where is the problem???? If a website works and another does not, it can be for a lot of reasons. Such as the web browser that you are using does not support java script, your firewall is blocking something, malwares and viruses sometimes would not let you open anything because of the search bars that yo got there.

I'm not sure about your technique, but sorry it does not help in most cases. :)

with regards
