The high resource occupancy of Chrome system can be solved by the following methods: 1. Disable or uninstall the resource-occurring extensions, especially ad blocking and video downloading plug-ins; 2. Turn off the hardware acceleration function to reduce the burden on the system process; 3. Clean up the browser cache and cookies, and reset settings if necessary; 4. Update Chrome to the latest version and check system compatibility. The above steps can be tried in turn, and in most cases, it can effectively improve performance problems.
Chrome's system resource occupancy is high, especially when the "System" process is too high, which is really a headache. There may be many reasons behind this problem, but fortunately, in most cases, some adjustments can be alleviated.

Check whether the extension drags down system resources
Although Chrome extensions are convenient, some plug-ins will frequently run scripts or request data in the background, causing increased burden on the system process. Especially ad blocking, video downloading and social tool plug-ins are most likely to "eat resources secretly".
- Operation suggestions :
- Enter
chrome://extensions/
to enter the extension management page. - Disable plugins that you don't use very often one by one and observe the usage changes of the "System" process in the task manager.
- If a plugin significantly affects performance, consider uninstalling or finding a lighter alternative.
- Enter
Some users report that installing multiple similar functional plug-ins (such as two ad blockers) will conflict with each other, increasing system overhead.

Try turning off hardware acceleration
Chrome enables hardware acceleration by default to improve web rendering speed. However, in some devices or driver environments, this may backfire, causing the "System" process to be extremely high.
- Close method :
- Open Settings → System → Use Hardware Acceleration Mode (if available).
- Turn off the switch and restart Chrome.
Note: After closing, the experience of web page scrolling, video playback, etc. may drop slightly, but if your computer is configured in a normal way or the graphics card driver is old, this operation is worth trying.

Clean up cache and reset settings
After using Chrome for a long time, excessive accumulation of browser caches, cookies and personalized settings may also lead to an increase in the load of background processes.
- You can try the following steps :
- Enter
chrome://settings/clearBrowserData
- Select "Past Hour" or "All Times" in the time range
- Check cookies and other website data, cache images and files
- Click to clear data
- Enter
In addition, you can also reset the browser settings to the default state through chrome://settings/reset
. This operation will not delete bookmarks and history, but will clear some potentially problematic configurations.
Update Chrome or check system compatibility
Sometimes the problem is not about you, but about the bugs in Chrome's own version or incompatible with the operating system.
- Make sure Chrome is the latest version : Click the three dots in the upper right corner → Help → About Google Chrome, it will automatically check for updates.
- View system environment : Especially for Windows users, you can try updating the graphics card driver or running system file checking tools (such as sfc /scannow) to troubleshoot system-level problems.
If you have done the above items but the "System" process is still high, you may be encountering compatibility issues with a specific website or service. At this time, you can try opening a new user profile to test it, or simply change your browser to see if it is a common phenomenon.
Basically these common ways of handling are. Although it seems a bit cumbersome, it only takes a few simple steps to improve.
