Newegg web page problem

I am unable to read any Newegg reviews. This started about 2 weeks ago & initially I thought it was something wrong on their end. But I have no problem when using my Chromebook.

I can click on & read the information under the tabs for Overview, Specifications, Warranty & Returns, and Q&A. But for the Reviews tab I just get the small spinning circle & the word “Loading”.

I also noticed the small spinning circle & the word “Loading” appears above the tabs. Normally in this area it would say “Buy Together & Save” or “Customers Also Bought” and show some items. But this data is also being blocked out.

This happens when I use Firefox 49.0.2 or IE11. I have cleared cookies, cache & temp files. I also tried with the firewall disabled but so far nothing has made any difference.

What kind of Windows setting would cause this problem?

I restored Windows back to 2 weeks ago & all is well. I wonder what happened during the last 2 weeks to cause this.

It's happening again. I restored Windows back to only 3 days prior & it made no difference. Have also ran Malwarebytes & SuperAntispyware and no malware found.

And ideas what is happening?

Did a lot of Googling & found this.
windows 7 - Unable to access most internet sites error DNS_PROBE_FINISHED_NXDOMAIN - Super User

I flushed the dns and everything seems to work OK.
