Google Chrome is the most used web browser in the world. And it’s the most popular web browser, in terms of features, user interface, and everything else, with fewer bugs and super-fast web browsing.

But one of the most nightmarish problems with Google Chrome is that its CPU load is too high. Many users report high CPU load when running Google Chrome, Windows 10 hangs and doesn’t respond when the Chrome browser is open.

What causes high CPU load in Google Chrome?

Outdated Flash Player plugin: For stability and security, the Flash Player should be updated constantly.

Suspicious extensions: If you’ve recently installed new plugins or extensions, check to see if they’re causing high processor load.

Lack of administrator rights: Users report that running Google Chrome as an administrator easily solves the problem.

One of the most common reasons for Google Chrome's high CPU usage has to do with the number and type of Google Chrome extensions you use. Generally, if you add more software packages (such as extensions, plug-ins, apps) to your system, you increase the risk that your computer will run slower. In general, not always.

If your power supply (laptop power cord, desktop power supply) is faulty, it may automatically start reducing CPU power to save power. If there is insufficient power, your processor can only run at a fraction of its maximum power. So it's possible that in Windows 10, this will manifest itself as 100% CPU usage.
