 this never happens in every websites but for few websites , please help me I don't believe the problem is with the websites you are trying to visit.  It's a problem with your internet connection.

More info about your hardware, software, and ISP would be helpful.  What are the specs on your computer?  What protection programs (firewall, virus, spyware) are you using?  Who is your ISP?  What type of internet connection (DSL or cable) do you have?  Hi,
