Google Chrome Helper acts as a bridge between our browser and external plugins so that they can work on the browser.

It’s essentially a very helpful tool for Chrome users, given the fact that it plays a really important role for many internet surfers.

Without bragging much regarding the matter, I’ll get us right into the causes and the possible fixes that can resolve the issue at hand.

Disable the use of hardware acceleration

As Google Chrome Helper drastically affects the device’s CPU, then the first thing we can do is prevent Chrome from making use of your CPU to offload tasks from the device.

Here are the steps to disable hardware accelerations:

  1. Launch the Google Chrome browser on a computer.
  2. Copy-paste the following address into the URL section.
    chrome://settings/onStartup.
  3. Scroll down to the very bottom of the tab and click on the Advanced button to expand options.
  4. Within Advanced settings, scroll to the System section.
  5. Under this section, toggle OFF Use hardware acceleration when available.

After you disable this option in Google Chrome, make sure to click the Relaunch button to successfully save the changes.

Turning it off will no longer give Chrome permission to utilize the CPU, thus fixing the issue of overutilization.

Drop off Installed Extensions

Certain chrome extensions that run in the background and require CPU usage might be the culprit of CPU’s overutilization. This can be prevented by removing such extensions from your Chrome browser.

Here are the steps to remove the Google Chrome Extension:

  1. Launch the Google Chrome computer browser.
  2. Click on the menu icon vertical 3dots icon at the top right side.
  3. Hover your mouse pointer over More tools and head inside Extensions.
  4. Find the extensions that directly influence the CPU and other elements of your device.
  5. Hit on the Remove button to delete extension.

Successfully removing such extensions from your Chrome browser will lift off the high tension and pressure your CPU takes. This ultimately results in a much lesser amount of CPU usage.

Block Ads on Chrome

Ads, as we know, can be harmful, irritating, and toxic at times. Although most of them serve no actual purpose, the Chrome browser will still pop them up, given the fact that you visited and gave permission to scam sites or apps.

Ads can be misleading while browsing. Not only do they scam you, but certain ads have the capability of influencing your device’s performance. This happens when your Chrome browser gives way for a lot of ads to overlap over time.

Ghostery – Privacy Ad Blocker

In order to prevent this, it is always suggested to use reliable ad blockers. You can either choose to go with ad-blocking extensions or antiviruses for ad blocking, which might be the more reliable option.

Antiviruses like AVG, Yahoo, and such offer in-built and automatic ad blockers, which will keep you safe to provide a convenient browsing experience. Making use of such ad-blockers will essentially take the load off the CPU, keeping it from being overutilized.

Bottom Line: Chrome Helper Overutilize CPU

That ultimately covers all the possible ways of fixing Google Chrome Helper from overutilizing your CPU.

Blocking ads play a really important role in fixing this issue. However, I strongly believe that the majority of the users already have an antivirus of their own, keeping the ads at bay for you.

As in my case, I already had Ghostery to block ads to deliver that tailored, convenient browsing experience.

That being the case, the solution for me was dropping off some of the highly demanding Chrome extensions that I had installed.

If you do have such extensions, I firmly believe that lifting them off from your browser will provide a drastic improvement regarding the situation where the CPU is overutilized.

However, if at all that isn’t working out for you, then disabling the use of hardware acceleration in Chrome will ultimately help you out. Good luck!

  2. I was having this issue on my macbook. I couldn’t figure out what was causing it. I would force close Google Chrome Helper and CPU usage would drop significantly. Sometime later, CPU usage would be up again. I would force close GCH again. At some point, I realized any Amazon.com pages I had open were not working. So now when I’m done shopping on Amazon.com. I close the window. I no longer have high CPU usage and constant fan running(not to mention fast battery drain), except when I have an Amazon.com window open. I have Honey coupon and Capital One coupon extensions on Chrome and don’t know if they’re the root cause of the problem. I like them and don’t want to get rid of them. They don’t affect any other websites I shop on. I feel it is the Amazon.com windows I leave open. At least for me it is. I usually have about 40-50 windows open. Lol

  3. Hi, the game I play online needs hardware acceleration.
    I have two extensions again for the game I play but are not needed during game play. Is it enough to disable them during game play then able them again afterwards or do the extensions need to be deleted to have any effect?

  4. This seems to be an old approach.

    I have hardware disabled for years, but still had a massive problem. Just tried turning it back on and it now works a treat on Amazon and phots.google.com – previously it was unusable,
