Steps to fix it Chrome showing not responding problem:

• Chrome will be reset to its default settings. It's always possible that something was corrupted or that a combination of settings resulted in an issue. The only way to be sure is to restore everything to the state it was in when you initially installed Chrome.
• Chrome should be reinstalled. If nothing seems to be working, try resetting Chrome to its default settings, uninstalling it, and reinstalling it. That is the most comprehensive approach to reset Chrome, but it is rarely necessary.
• Clear the DNS cache on the computer. DNS caches have an impact on network connections, even but they are unrelated to Chrome. DNS enables the browser to locate websites using URLs rather than IP addresses. It's preferable to clean it out in case something has gone horribly wrong or has become corrupted.
• Contact Google Chrome's customer service. If all else fails, you might have to contact Google customer service to get the problem resolved.
