Recently installed Windows 7 Home Premium on new home-built computer. I've noticed that I can't login on some websites using any browser (have tried IE8, Firefox, and Chrome). Websites I can't login to: Newegg.com (address: https://secure.newegg.com/NewMyAcco...secure.newegg.com/NewMyAccount/DashBoard.aspx) XFX support (address: http://www.xfxforce.com/en-us/Help/Support.aspx) I can login to Newegg if I select the "Remember my Newegg ID" box. The XFX support site has no such option. Also, is it a coincidence the sites I can't login to are all .aspx? Some websites I can login to: Gmail, Netflix, Amazon, Microsoft Live ID sites, banking sites. I've tried clearing personal data in each browser, changing cookie settings, reinstalling Java, reinstalling antivirus software, disabling antivirus software, starting Windows in Safe Mode w/ Networking, accessing the sites on another user account, manually setting DNS. Nothing has helped so far. Other computers on the same LAN can login to the sites fine. Any ideas for a solution? Thanks.
