Steps to do when there is a problem to open Google Chrome:

• Chrome should be updated to the most recent version. Select Settings > Help > About Google Chrome to launch a new tab with information about the Chrome installation before you start searching around in Chrome and risk deleting settings. Chrome will look for a newer version at the same time. Chrome will update itself if it detects one.
• Clear the cache and history. Your day can be ruined by a corrupted cache. Clearing the cache is usually always safe, so there's no reason not to try it. You should also remove your internet history. Remove any data that could have been corrupted.
• Restart the computer. Rebooting the machine flushes the system RAM and presents Chrome with a like-new environment if Chrome encountered a memory problem relating to how the operating system allocates active RAM.
• Extensions should be disabled. Extensions are an important aspect of the Chrome ecosystem since they provide the browser new capabilities.
• Clear the DNS cache on your computer. DNS caches have an impact on network connections, even though 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 wrong or has become contaminated.
• Check to see if your firewall is preventing Chrome. If you've made any changes to your firewall, double-check that the new settings don't prevent Chrome from working.
