Google Chrome Using Too Much RAM and CPU on Windows 11? Here’s Why

Google Chrome is one of the most popular web browsers in the world, known for its speed, stability, and feature-rich experience. It’s regularly updated to improve performance and security. However, while using the browser, you may notice Chrome taking most of the CPU and RAM resources and making your PC feel sluggish. Some Windows 11 users have reported that Chrome is using 80–90% memory, especially after installing system updates. Others mention that webpages take several minutes to load, even when their internet connection is stable. Corrupted cache, too many background processes, resource-heavy extensions, or malware/adware interference are among the most common causes behind this behavior. Whatever the reason, here is how to fix and reduce Google Chrome’s High CPU and RAM Usage on Windows 11.

Why Chrome taking most of the CPU and RAM resources?

Chrome uses a multi-process architecture, which means every tab, extension, and background service runs in its own process. This improves stability if one tab crashes, the whole browser doesn’t but it also means Chrome consumes more memory than many other browsers.

High resource usage is also caused by the number of open tabs, demanding websites with media like videos, and extensions running in the background.

• Too Many Open Tabs: Each tab runs in a separate process. The more tabs you keep open, the more memory Chrome will consume.
• Resource-Heavy Websites: Pages with auto-playing videos, animations, ads, or interactive elements (like YouTube, Google Drive, or live dashboards) require more CPU and RAM to load and run smoothly.
• Corrupted Cache or Browsing Data: Over time, Chrome’s cache and cookies can become bloated or corrupted, leading to slow performance and excessive resource usage.
• Chrome Running Background Processes: Even after closing the browser window, Chrome may keep some tasks running (e.g., notifications, extensions, or apps), continuing to consume system memory.
• Outdated Chrome or Windows Version: Older builds may contain bugs or performance inefficiencies that lead to memory leaks or CPU spikes.
• Malware, Adware, or Browser Hijackers: If your PC is infected, Chrome may be forced to load hidden ads, pop-ups, crypto miners, or scripts in the background, significantly increasing CPU and RAM usage.

Pro Tip: Open Chrome’s Task Manager by going to More tools > Task Manager to see which specific tabs or extensions are consuming the most resources.

Close Unneeded Tabs (or Suspend Them)

Every tab runs in its own process. Ten active tabs can easily consume gigabytes of RAM. Suspending or closing idle tabs instantly frees memory.

• Press Ctrl + L, then type the site you need close the rest.
• Right-click a tab → Add tab to new group → collapse groups to reduce clutter.
• Also, you can install a lightweight tab suspender (e.g., “Auto Tab Discard”) to auto-sleep inactive tabs

Update Google Chrome

An outdated version of Chrome can have bugs or performance issues that cause high CPU or memory consumption.

Chrome works best when you’re on the latest version.

• Open Chrome browser and go to chrome://settings/help
• This will automatically check for and download the latest Chrome version.
• Once done, relaunch the application.

Close Background Apps and Chrome Processes

Chrome continues running background apps even after closing the browser, consuming CPU and memory.

• In Chrome, go to Settings → System. Also, you can go from here, chrome://settings/system
• On the “System” section, toggle off the “Continue running background apps when Google Chrome is closed” option.
• Also, Toggle Use hardware acceleration when available Off.

In addition, Open Task Manager (Ctrl + Shift + Esc). End any Chrome processes still running after closing the browser.

Disable or Remove Unnecessary Extensions

Extensions run background scripts and content scripts on pages. Poorly optimized ones cause CPU spikes and memory leaks.

• Click the three dots (⋮) → Extensions → Manage Extensions.
• Toggle off or remove extensions you don’t use.
• Click on the delete icon to remove any extension.
• Restart Chrome and check if performance improves.

Clear Browsing Data and Cache

Chrome stores cached resources to load sites faster. Over time, Chrome accumulates cached files, cookies, and temporary data that may slow down performance or cause memory leaks.

• Press Ctrl + Shift + Delete or Go to chrome://settings/clearBrowserData
• Choose All time in the time range.
• Select Cached images and files and Cookies, and other site data.
• Click Clear data. Restart Chrome and check if the CPU or RAM usage comes down.

All of the steps above must help you to reduce Chrome CPU usage. But if you still face high CPU and RAM usage issue, You can take the following steps.

Scan for Malware or Adware

Malware, browser hijackers, and hidden mining scripts often run inside Chrome, causing heavy CPU and memory usage. Cleaning malware removes these hidden processes and instantly improves performance.

• Open Windows Security → Virus & threat protection.
• Click Quick scan or Full scan.

Alternatively, use third-party antivirus or anti malware program to perform a deep scan.

Reset Google Chrome Settings

If none of the above steps work, resetting Chrome to its default settings can resolve hidden configuration or extension conflicts.

• Go to chrome://settings/reset
• Click Restore settings to their original defaults.
• Confirm by clicking Reset settings.

Note: This will remove extensions, custom startup pages, and pinned tabs, but it won’t delete bookmarks or saved passwords.

Reinstall Google Chrome

If Chrome installation files are corrupted, a fresh install can completely fix performance issues.

1. Press Windows + I to open Settings, go to Apps, then Installed apps.
2. Search for Google Chrome and click three dot menu then click Uninstall.
3. After uninstallation, delete Chrome’s user data folder:
   C:\Users\Username\AppData\Local\Google\Chrome\
4. Visit google.com/chrome to download and install the latest version.

FAQ – Chrome High CPU and Memory Usage on Windows 11

1. Why does Chrome use more RAM than other browsers?
Chrome isolates every tab and extension into a separate process for better stability and security. While this uses more memory, it prevents one crashed tab from affecting others.

2. Is it normal for Chrome to use a lot of CPU?
Mildly high CPU usage is normal when streaming videos, using web apps, or opening many tabs. However, consistently high usage even when idle indicates a problem.

3. Does hardware acceleration increase CPU usage?
It usually reduces CPU usage by shifting work to the GPU, but if your GPU driver is faulty, it can have the opposite effect. Disabling it sometimes helps.

4. Will reinstalling Chrome delete my data?
If you’re signed in with your Google account, your bookmarks, passwords, and history are synced to the cloud. Reinstalling won’t delete that data.

5. Can malware cause Chrome to use too much memory?
Yes, malicious scripts and browser hijackers can run hidden background processes that spike CPU usage. Always perform a malware scan if usage is unusually high.
