I think you are suffering from a critical issue, though I'll try to give some solutions.
1. Disable the IPV6 from your system (perform following steps to disable IPV6 http://www.techunboxed.com/2014/10/how-to-disable-ipv6-in-windows-10.html
2. Replace the CMOS battery, as I think you might have replaced the faulty battery.
3. Check whether the website you are accessing is blacklisted in Firewall or in Antivirus, or try to disable Antivirus and Firewall.
If all the above options won't work, you must reinstall the windows 10.
