Solution 1: Clear cache and cookies

You can firstly try to clear cache and cookies in Chrome, because some old cached files or nasty cookies may be causing the trouble. Here’s how to clear cache and cookies in Chrome:

  1. At the top right in Chrome, click the three dots > More tools > Clear browsing data.

  2. From the Basic tab, set the Time range to All time, and select all the checkboxes below.

  3. From the Advanced tab, set the Time range to All time. Select the types of information you want to remove. Make sure Cookies and other site data, Cache images and files are selected.

  4. Click Clear data.
  5. When the data is cleared, type chrome://restart in the URL bar then press Enter to restart Chrome and check if the problem is resolved. If not, try Solution 2, below.


Solution 2: Disable unnecessary extensions

Chrome extensions are also known to cause Chrome high system resources usage, such as 100% CPU, memory or disk usage. If you’ve installed a number of Chrome extensions, they may be the culprit for Chrome high CPU usage. We recommend disabling or deleting them one by one. Then restart Chrome and see if Chrome high CPU usage is fixed.

  1. Type chrome://extensions in the URL bar and press Enter to open the Chrome extension manager, where Chrome extensions are installed.

  2. Toggle off all extensions to disable them.
  3. Restart Chrome and test if the issue is fixed. If not, move on to Solution 3, below.

Solution 3: Reset Chrome settings to default

Resetting Chrome to its default settings is another useful solution to Chrome high CPU usage. This rules out all man-made causes. You can follow these steps to reset Chrome settings to default:

  1. At the top right in Chrome, click the three dots > Settings.

  2. At the bottom, click Advanced.

  3. Under Reset and cleanup, click Reset settings to their original defaults > Reset Settings.

  4. Relaunch Chrome and test. If the problem still exists, try Solution 4, below.

Solution 4: Update your device drivers

If the steps above didn’t resolve your Chrome high CPU usage problem, it’s most likely caused by a device driver. You can update all your device drivers to the latest version to help fix the problem.
