I am using Windows 8 64-bit and I am having an issue loading certain websites. Twitter and Facebook are the main two. I have tried Chrome, Firefox, IE, Chrome portable, Firefox portable and qupzilla portable. I tried using https as well. http://en-gb.facebook.com loads but once I enter my login details it just comes up with "problem loading page" again. I have run Malwarebytes and SUPERantispyware I have cleared cache's etc and nothing seems to be helping. Any help would be greatly appreciated as I'm almost at my wits end with it. I should add I've reset my router, restored factory settings but they seem to work on other devices (android phone, old laptop etc).
