How to Troubleshoot Google Chrome’s High CPU and Memory Usage

Google chrome is definitely one of the fastest web browsers currently . While it Might be able to beat down all its contenders hands down , Chrome does has a weak point . When it comes to memory usage , sometimes chrome may act a little weird and consume a lot of your ram and CPU’s resources . This might cause your computer to lag and even may lead to blue screens .


A similar problem happened with me a few days back . I have been using Google chrome for a long time . Out of nowhere one day Google chrome started to consume up a lot of my computer’s ram and CPU resources and even led to a many blue screens . Everytime when i rebooted, my computer worked flawlessly but when i opened a website on Google Chrome , Chrome started to lag my computer and eventually lead to another blue screen . With frustration i started searching for solutions and fixes online .

I followed most of the solutions and fixes i could find  but nothing seemed to work . So i tried checking each and every setting of Google chrome and eventually i found a solution . The culprit was one of my Google chrome extensions and removing all the extensions solved the problem . though my problem was a extension , the same might not be in your case .

If you have a similar problem where Google chrome is consuming a vast amount of your computers ram , then let me provide you some brief instruction on how to troubleshoot this annoying problem . Simply follow all the methods below , as one of them should definitely work for you .

Method 1 : Use Google Chrome’s inbuilt task manager

Google chrome has a inbuilt task manager ? yes it apparently does . Its made for advanced users but everybody can benefit from it . To bring up the task manager on Google chrome just press the following key combination ( Shift + Esc ) .



The Task manager in Google chrome shows how much resource every web page and each of the chrome extensions are using . Right click on any process and you can select from more categories of information . If you find any of them fluctuating and using too much of your ram and CPU resources . Changes might be that the page is infected or the extension is malfunctioning . select the process / extension and end it . do a thorough scan of your system for any malware infection that could have happened possibly .

Method 2 : Remove all the extension in Google chrome 

Sometime one or multiple plugins can be the reason why Google chrome uses a lot of your computers resources . use chrome’s extension manager to find out which of the extension is using more resources . Select the extension and end it . Restart chrome and if the plugin works normally then the problem is solved . If the problem still exists then Remove the extension from chrome and reset chrome to set it back to normal .

Method 3 : Reset chrome

If you can’t find any problem through the above steps then thy Resetting Chrome . It  fixes most of the problems wit chrome . Before resetting chrome , do sync your bookmarks and other data with your Gmail account so that you don’t lose them .


If you follow these two steps then most probably your problem will be solved . If it doesn’t then do add a comment below . i will try to find some solution through my resources .

    Very good tips!

    Great tips!

    Thanks. I have very recently been having super high lag and traced it back to 1000% (yes, that is one thousand!) CPU usage in a single chrome process, as measured by the built-in Resource Monitor in win7. Through trial and error, found a couple sneaky extensions had installed themselves in chrome. In my case, these were “searchnewtab”, “surfanddkeep”, and “youtubeadblocker”. Not sure which one was doing the damage, but removed all! Turns out some very nasty malware was hiding in my extensions.
    Thanks for putting this info up! Really helpful!!!

    • Linda Melfi Stockbridge

      Globurs, how did you even find the three sneaky extensions?? How did you arrive at those?

      • OMA

        A process using 1000% of the CPU. How can it be even possible? Does your computer have 10 CPU processors inside? ;-)

  • TestTickle

    ugh, you techs! how do you reset the browser? i didnt understand any of this. the only thing i was able to do was to bring up the task manager. after that, the directions meant nothing to me.

    • shufflemoomin

      How is that anyone else’s fault?

      • TestTickle

        If the instructions are for a general audience with no specific training, they should be clear, detailed, avoid technical terms, and provide illustrations. Just as companies do product testing, they could do instruction testing. It’s called being user-friendly, and it is something most products try to achieve. There is nothing wrong with my asking that the instructions be made more user-friendly.

        • OMA

          For me it was pretty obvious that the “Reset browser settings” screen capture shown in Method 3 was from the Settings menu, but I can understand that some people never used the Settings menu and might not know where that button is. Anyway, you could have just googled the words “reset chrome”, and the FIRST result explains where to find that.

    playing a game on fb is using around 40-50 of my cpu which wasnt the case earlier.
    I hav removed al extensions but still no help

  • submitter

    depending on certain webpages, it can use a lot of resources. i was surprised my cpu temp jump to 65C from normal operation of 45C. Loud noise from fan with its speed jump to 2300rpm from normal oprtn 1500rpm.

    press ctrl+al+del , and end all those chrome processes. temp return to normal. and reclick chrome and continue browsing.

      Seems to be a bad extension for me. If you ever face the same problem again, check which extension is using the highest resource. That might be your culprit.

    • Solidpeag

      This is where I’m at, though same problem recurs if visiting the same webpages is a necessity for the task at hand.

  • Leanne

    Chrome has become a useless piece of bloatware. Developers still use it because it often has leading edge features. If you think Chrome on Windows is bad, you should try Chrome on Android. Google should be embarrassed.

  • Gisle Lie

    Bad tips.. Resetting makes it good for 1-2 days. Disabling extensions makes no difference. And checking the task manager does nothing but inform you that flash is using a fuck load of CPU. Can I get a job and give shitty tips as well?

    • lovejeet

      Hi Gisle, i try to share all that i know through this blog and this doesn’t mean i know everything. Most of the time its the visitors comments on my blog from which i learn new things. All the how to guides and tips that i provide on my blog are thoroughly tested by me on my PC. I wouldn’t dare to post them if they didn’t work at first. The problem is we all use computers with different specs, Which is why my tips will work for some and for some they wont.

      Indeed, problem I have is that YouTube Flash now takes up 100% of CPU (using process monitor) so sound breaks up – even if I pause to let it download ahead – seems to be in playback. Adjusting to low res doesn’t help. There ought to be a law against automatic (forced) updates the incur more resources. I still use XP because, unlike Windows Vista, 7, or 8, I am still allowed unfettered access to my computer – just imagine if you bought a car and were not allowed to look under the hood. That’s Bullshit!!

    • ALX

      Are you just commenting to be a douche or do you have some alternative input rather than criticizing on what does not work for you. Seems like you know the ins and outs so let’s hear some good tips. Also if you think you can do it better just:
      -make your own blog
      -incorporate relevant information that will attract the type of visitors you want
      -link your site to all you’re preferred social networking groups that keeps your sites traffic flowing
      -hope that you have enough credible info that people can use are willing to spread the news about your site that you’ll run out of bandwidth allowing you to step up your game
      -and soon you too will be paid for your “shitty” advice
      Best of awareness to you, because narrow mindedness gets us nowhere.

      Thank you Lovejeet for sharing your knowledge although it does not help everyone you at least help some… Keep up the geek.

    Never knew about that task manager. Found out a single ebay tab was using up about 15% cpu usage

  • Jeff Yan

    Thanks so much! It works for my chrome.

  • Invariable_Muse

    Thanks so much. I didn’t even need to delete an extension, just disabling it and immediately selecting it again freed up all my cpu!

  • artan bruci

    thanks so much it worked for me to

  • Random Guy

    I dont use a lots of extensions but i deleted one same prob and 2 more are there but i need them is there a another way

  • Bruno Piazera Larsen

    i tried all of those solutions but now i have a just install chrome, with no plug-in other than the ones it comes with and it still gets 15 to 20% of the cpu of my i7 4770k. when i use the inbuilt task manager it says that the browser isusing all the cpu, not one specific page, so how can i deal with that?

  • kamel berrayah


    This is something wrong with google chrome , it’s not normal to use up to 2GO for just three tab and some modest thre extensions ( like adblock )

  • Henry_S

    Bafore this started to happen Spring of 2014 I could open as many tabs as I desired with no issue…Then an update to Flash and its been hell since…I have also noticed that if you let facebook sit open it will consume the memory and rise to a gig or so.
    The only shortcut way out for Me is to click a new tab then close the facebook tab, then go back to facebook on the new tab. (and Your still logged in) Do We can ask Adobe and facebook whats the deal? I think it is closer to something facebook is doing such as feeding rotation weather ads or live feed. not releasing any memory.

    Hello, I have Windows 7 and the past few days have been receiving a Norton Performance Alert for High CPU usage for Google Chrome. And also, my computer has been running very poorly, so I removed Google Chrome to resolve the problem. I am still getting the Norton Performance Alert for High CPU usage for Google Chrome, even though it is uninstalled. When I click on the details in the Performance Alert it says qmoqcpdgc.exe. next to a Google Chrome icon. I click ‘locate’ and it in the C drive listed as an application and is 841 KB in size. When I highlight and delete, it says, ‘the file can’t be deleted because it is open in Google Chrome. Close the file and try again’. The high CPU problem was happening while Google Chrome was installed and is still happening after I uninstalled it. How can I delete this ‘qmoqcpdgc.exe.’ application file at this point? The alert is popping up every few minutes and right this minute! My computer fan is non stop and I’m afraid my computer is going to crash at any moment. Thank you for your help!

      You can try to uninstall and reinstall google chrome and if the problem persists, scan your computer using an antivirus program.

    Processes running show Dxptaxluzwsp.exe listed about twenty times. Shows as a Google file. I have tried going into safe mode and deleting the Dxptaxluzwsp.exe file but when I reboot it seems to return. Also my desktop keeps refreshing about 30 seconds. Any ideas how to completely remove Google?

    • Lovejeet

      It seems your PC is infected with a virus. You need to perform a thorough scan using an antivirus program.
