It is not uncommon for web browsers to consume a moderate to large percentage of your computer’s resources, especially when you use Flash or Java in one or more tabs. If you notice a CPU peak when browsing some pages, they may contain incorrect code or, in the case of sites such as YouTube or Netflix, may use extensions that require a lot of resources. However, if Google Chrome has a consistent and high CPU usage, regardless of your browser activity and your browser is up to date, you may need to disable some plug-ins or improvements or reset the application to its default settings.

Why does Google Chrome consume so much CPU?

Virus/malware infection analysis


Most of the time, virus infections, corrupted caches, cookies, browser history, etc. make the chrome browser unattractive and use high system resources such as hard disk, memory or 100% CPU.

Install a good antivirus/anti-malware application with the latest updates and perform a full system scan to ensure that infection by malware does not cause the problem.

Keep your Chrome browser up to date.

Google regularly updates your Chrome browser to fix bugs and add new features that improve usability.

  1. Go to the Chrome Customization menu in the upper right corner of the browser window and click on the Help option at the bottom of the menu list.
  2. Select About Google Chrome to check for updates.
