I'm seeing a blank page when I try to visit Sign in to your Microsoft account It's not working in Chrome, Firefox or IE, but it does work in Tor browser. I'm using a Windows 7 PC which is connected via Ethernet. I can view Sign in to your Microsoft account on my Windows 8 laptop which is connected via WiFi. this works using any browser on my laptop. on my PC, I can't sign-in to any Microsoft website or application. I open OneNote and it shows me the sign-in screen: http://i.imgur.com/57IdVso.png I enter my Microsoft email address and click 'Next', then the log-in box goes completely blank: http://i.imgur.com/S1BQ5nK.png I tried flushing my DNS settings. my IPv4/6 properties are set to obtain an IP address automatically. I'm seeing nothing unusual in Fiddler/network inspector... 200, OK. no other websites are blocked, just Microsoft's log-in pages. the most annoying thing is that the Microsoft help forums require you to sign-in to your Microsoft account. can't get technical support over the phone because that is a paid service. any ideas?
