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 .

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 .

  1. 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!!!

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

  2. 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.

      • 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.

        • 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

  4. 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.

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

  5. 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.

  6. 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?

    • 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!!

    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!

  8. 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

  9. 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?
