When you browse the Internet using your computer, your system hangs for a few seconds, then resumes as normal, and hangs again. When you open Task Manager, you’ll see that Google Chrome is using a large percentage of your CPU. You may be wondering how Chrome can consume so much of your CPU. There are many possible reasons for Chrome’s high CPU usage, but there are also 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.
What causes Google Chrome’s high CPU usage in Windows?
There are several reasons that can cause Google Chrome to run at excessive performance and take up all the CPU power. See the list below for a closer look at the scenario and to solve the problem!
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!
Before doing so, however, make sure you have at least 3 GB of free space on your hard drive.
Note that if you have a lot of open YouTube videos in Chrome with 4K/1080HD resolution, it can also cause high CPU load.
Why does Chrome use so much CPU?
There are several reasons for Chrome’s high CPU load. Let’s list some of the reasons. You can avoid these reasons by keeping your Chrome browser healthy for a long time.
1.) Opening too many tabs or windows at the same time.
2.) Using resource-intensive extensions or apps.
3.) Malware can also affect Chrome’s CPU usage.
Google Chrome has a tool for reporting on malware affecting your browser. Sometimes the reporting software can also consume a lot of CPU power. In this case, you can simply disable the reporting software.
If you have many tabs open at the same time, you can use the Chrome extension “The Great Suspender”, which will offload inactive Chrome tabs from your computer memory and save a lot of RAM and CPU power.
How to fix the “High CPU consumption” error in Google Chrome?
Keep Chrome up to date
Google regularly updates the Chrome browser to fix bugs and add new features that improve the user experience. To get the best performance from Chrome, it’s important to update to the latest version. Chrome automatically updates when you’re connected to the internet.
However, if you’re having trouble updating, you can do it manually.
1.) Go to the Chrome settings menu in the upper right corner of the browser window and click on the “Help” option available at the bottom of the menu list.
2.) Select “About Google Chrome” to check for updates.
3.) Chrome will automatically check for new updates and install them.
Fewer open tabs
So consider closing some of the tabs that are not currently in use.
This can potentially minimize CPU and memory usage.
1.) To close a particular tab, click on the tab’s “X” or use the Control + W or Command + W shortcut.
2.) In Windows, you can also close multiple tabs at once by right-clicking on a tab and selecting either the option to close all other tabs or the tab to the left of the selected ones. Unfortunately, this option is not available in the Mac version of Chrome.
Disable unwanted apps and extensions
One of the many benefits of the Chrome browser is that it offers a wide range of extensions and web apps. These extensions and apps help you get your work done much faster. However, some of these apps and extensions can be very resource-intensive and interfere with your browsing experience.
1.) To remove a web app from Chrome, type “chrome://apps/” in the address bar and press Enter.
2.) Right-click the app you want to remove, click “Remove from Chrome,” and when prompted, click “Remove.”
3.) For extensions, use the URL, “chrome://extensions/” to see all installed extensions. Toggle the blue switch to disable the extension (the switch turns gray).
4.) Click the “Remove” button to get rid of unnecessary extensions, and confirm the action by clicking the “Remove” button again when the pop-up window appears.
Using Chrome Task Manager to manage CPU and memory usage.
Chrome’s high CPU and memory usage may be due to certain tabs or processes running in the background. Like the Windows task manager, Google Chrome has a separate built-in task manager. You can use it to monitor and stop resource-intensive processes.
1.) Go to the Chrome menu and select the “More Tools” option.
2.) Select “Task Manager” from the advanced menu.
3.) Here you can see the memory and CPU usage for each tab, app, or other Chrome processes.
4.) To stop a process, select it and click the “End Process” button at the bottom of the Task Manager window.
Use the Chrome Cleanup Tool to check and remove malware.
Sometimes malware and extensions can affect your browser and cause processor or memory overload. Google offers a special Chrome cleanup tool for the Windows version of the browser only.
It scans and removes suspicious software, including extensions and adware.
1.) Open Chrome settings at the URL “chrome://settings/”.
2.) Scroll down and click “Advanced” to open more settings.
3.) At the bottom of the advanced settings page, select “Clear Computer”.
4.) Click the “Search” button to search your computer.
5.) Chrome will search for the malware and then you can click “Uninstall” to remove it from your PC.
On a Mac, you must use third-party tools to clean up the malware.
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.
- Reboot. First step: Save your work and restart your computer.
- Stop or restart processes. Open the task manager (CTRL+MINUTER+ESCAPE).
- Update the drivers.
- Check for malware.
- Power options.
- Find specific instructions on the Internet.
- 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.
