Hi
Open Chrome, click the wrench icon (top right), Settings, Network, Change Proxy Settings, Change LAN settings.
Unclick the box, Automatically Detect Settings, if it is clicked.
If this doesn't work, what happens if you try and open the same pages in another browser like I.E.?
If the pages will open in other browsers but not Chrome, uninstall and reinstall Chrome.
Also it's worth the time to run Malwarebytes to make sure it isn't some kind of malware bug.
