The system hangs after browsing the Internet for a few seconds, then resumes as usual, and hangs again. You may wonder how Chrome can consume so much of your CPU when you open Task Manager. When you open Task Manager, you can see that Google Chrome is taking up a significant portion of your CPU. Chrome’s high CPU usage has many possible causes, as well as many possible solutions.

It’s not uncommon for web browsers to consume a moderate to a large percentage of your computer’s resources, especially when using Flash or Java in one or more tabs. If you notice a CPU spike when viewing certain pages, they may contain buggy code or, in the case of sites like YouTube or Netflix, use resource-intensive extensions. However, if Google Chrome has consistently high CPU usage regardless of browser activity and the browser is updated, you may need to disable some plugins or extensions or return the application to its default settings.

Why is Google Chrome so slow in using CPUs in Windows?

What causes Google Chrome's high CPU usage in Windows

This is due to several reasons, which can lead to excessive CPU usage and unacceptable performance from Google Chrome. Find out what the reasons are below and how to fix them!

Lack of administrator privileges: Users report that using Google Chrome as an administrator makes it easy to solve the problem.

Suspicious extensions: If you have recently installed new plugins or extensions, you should check if they are responsible for high CPU load.

Outdated Flash Player Plugin: Flash Player must be constantly updated for stability and security reasons. So, install the latest version as soon as possible!

High Memory Usage By Chrome

There is a lot of RAM being used by Chrome due to your browsing habits. Chrome is being reported to use up to 50% of the memory in your browser. 

You should, however, ensure that your hard drive has at least 3 GB of free space.
Chrome can also consume a lot of CPU if you have several YouTube videos open at 4K/1080HD resolution.

Why does Chrome consume so much CPU?

Why does Chrome use so much CPU

The Chrome browser has a high CPU load for several reasons. Let’s look at some of them and discuss ways to avoid them.

Overwhelming yourself with tabs or windows.
Extensions and apps that use a lot of resources.
In addition to affecting Chrome’s CPU usage, malware can also cause it to crash.

In Google Chrome, you have the option to disable the tool that allows you to report malware attacking your browser. Unfortunately, the tool can also consume a lot of CPU power.

Chrome’s “The Great Suspender” extension will save a lot of RAM and CPU power by removing inactive Chrome tabs from your computer memory if you have many tabs open.

This software will help you fix your PC problems and prevent others from happening again:

How to fix the High CPU consumption error in Google Chrome

Keep Chrome current

Update your Chrome browser regularly to get the best performance. Google automatically updates Chrome whenever you are on the internet so that you are always running the latest version.

It is, however, possible to manually update if you are having trouble.

At the bottom of the Chrome settings menu, click the “Help” option in the upper right corner of the browser window.
You can check for updates by selecting “About Google Chrome”.
Updates will be checked and installed automatically by Chrome.

Fewer open tabs

The Chrome browser has some nice tab management options, but if you have many open tabs, the computer’s processor and memory will be overloaded. Having multiple tabs open for sites such as YouTube and Netflix that use heavy Flash or JavaScript elements can make this even worse.

Why Does Chrome Use So Much Memory

A Chrome application that uses too much memory, on the other hand, could cause problems, since it limits the amount of memory that can be used by other applications. You might even lose access to important browser information, negating the purpose of using the RAM at all if Chrome is struggling to keep it available for quick access.

High Memory Usage Google Chrome

A temporary Chrome file is stored in RAM. 

With 6 Intel Cores running macOS Monterey 12.x, Firefox (currently v104) uses the least amount of CPU on the Zendesk Agent Interface. Other browsers seem to use significantly more CPU.

Depending on how many extensions are installed, Google Chrome might use 30% of the CPU for some users, while it might use 60%-80% or even 100% for others.

It is therefore advisable to close non-used tabs.
Memory and CPU usage can potentially be minimized by doing this.

1). Click the “X” on a tab to close it or press Control + W or Command + W to close a particular tab.
In Chrome for Mac, the option to close all tabs is not available. However, in Chrome for Windows, you can close all tabs by right-clicking on each tab and selecting the option to close the ones to the left.

Unwanted extensions and apps can be disabled

In addition to providing a wide array of extensions and web apps, Chrome offers many other benefits as well. You can get your work done much faster with these extensions and apps, but some of them can consume a great deal of resources and interfere with your browsing experience.

In the address bar, type “chrome://apps/” to remove a web app from Chrome.
If prompted, click “Remove from Chrome” in the upper-right corner of the window when you right-click the app you wish to remove.
2.) You can disable extensions by untwisting the blue switch next to them (the switch will turn grey if you disable the extension). 3.) For extensions, use the URL “chrome://extensions/” to view all installed extensions.
When the pop-up window appears, click the “Remove” button again to confirm eliminating unnecessary extensions.

Chrome Task Manager is a tool to monitor CPU and memory usage.

Google Chrome has a built-in task manager that can be used to monitor and stop resource-intensive processes that are using a lot of CPU and memory. Like Windows Task Manager, Chrome’s task manager helps you monitor and stop these types of processes.

1) Select “More Tools” from the Chrome menu.
You can access the advanced menu by selecting “Task Manager.”.
Each tab, app, or Chrome process will be displayed here, as well as the amount of memory and CPU they are using.
The bottom of the Task Manager window contains the “End Process” button you can click to end a process.

To remove malicious software, use the Chrome Cleanup tool.

Chrome has a special cleanup tool for Windows users only. Malware and extensions can slow down the browser and cause it to run slowly or crash.
Including extensions and adware, it scans for suspicious software and removes it.

Visit the URL “chrome://settings/” in Chrome to open Chrome settings.
You can access more settings by scrolling down and clicking “Advanced”.
Choose “Clear Computer” from the advanced settings page.
You can search your computer by clicking on the “Search” button.
You can remove the malware from your computer by clicking “Uninstall” after Chrome searches for it.

Cleaning up malware from a Mac requires third-party tools.

Most Frequently Asked Questions

One of the most common reasons for Chrome's high CPU load has to do with the number and type of extensions you use. Generally, when you add software (extensions, plug-ins, apps, etc.) to your system, you increase the risk of your computer slowing down. In general, not always.

  1. Reboot. First step: Save your work and restart your computer.
  2. Stop or restart processes. Open the task manager (CTRL+MINUTER+ESCAPE).
  3. Update the drivers.
  4. Check for malware.
  5. Power options.
  6. Find specific instructions on the Internet.
  7. Reinstall Windows.

Slow processing can have a variety of causes, some of which are harder to solve than others. But in most cases, if you're wondering how to reduce CPU usage, the process is actually as simple as pressing Control + Shift + ESC.

Unfortunately, it is becoming increasingly common for malicious Chrome extensions, poorly designed extensions, or monetizing extensions to cause excessive CPU or memory consumption on your computer from Google Chrome. This can cause Chrome and Windows to slow down, freeze, or crash.
