Google Chrome browser freezes - what do I do?

A common complaint from Google Chrome users is that the browser slows down. Chrome lags in different ways: sometimes it takes a long time to start the browser, sometimes it lags when opening sites, scrolling through pages, or playing video online (there is a separate guide for this last topic: Online video is lag in browser).

This guide details how to find out why Google Chrome lags on Windows 10, 8, and Windows 7, what causes its slow performance, and how to fix the situation. It can also be useful: Google Chrome runs out of CPU 100%

Use Chrome's task manager to find out what's causing its slowness

You can see the CPU, memory and network load of the Google Chrome browser and its individual tabs in the Windows Task Manager, but not everyone knows that Chrome also has its own built-in task manager that shows the detail in detail. load caused by various browser tabs and extensions that are running.

To use the Chrome task manager to find out the cause of the slowdown, follow the steps below

  1. While you are in the browser, press the Shift + Esc keys: the built-in Google Chrome task manager will open. You can also open it through the menu - Advanced Tools - Task Manager.
  2. In the task manager that opens, you will see a list of the open tabs and their RAM and CPU usage. If, as in my screenshot, you see that some particular tab is using a significant amount of CPU (processor) resources, in all likelihood there is something going on in it that is detrimental to your work, nowadays most often they are miners (not uncommon in online movie theaters, "free download" resources, and the like).
  3. If you wish, by right-clicking anywhere in the Task Manager, you can display other columns with additional information.
  4. In general, you should not be confused by the fact that almost all sites use more than 100MB of RAM (assuming you have enough) - for today's browsers this is normal and also usually works for faster operation (as site resources are not shared over the network or to disk, which are slower than RAM), but if a site stands out strongly, it is worth paying attention to and possibly terminating the process.
  5. The "GPU Process" task in Chrome's Task Manager is responsible for running graphics hardware acceleration. If you're loading the processor a lot, that could be weird too. Maybe something is wrong with your video card drivers, or you should try disabling hardware graphics acceleration in your browser. It's also worth trying the same if page scrolling is slow (takes a long time to redraw, etc.).
  6. The Chrome Task Manager also shows the load caused by browser extensions and sometimes if they are not working properly or have unwanted code embedded (which is also possible), you may find that the extension you need is exactly what which is slowing down your browser.

Unfortunately, it is not always possible to find out the cause of the browser lag using the Google Chrome Task Manager. In this case, you should consider the following additional points and try other troubleshooting methods.

Other reasons why Chrome is lagging

First of all, it must be taken into account that modern browsers in general and Google Chrome in particular are quite demanding with the hardware characteristics of your computer and, if your computer has a weak processor, a small amount of RAM (4 GB for 2018 - not enough anymore), problems may be caused by this. But these are not all possible causes.

Among other things, there are points that can be useful in the context of solving the problem:

  • If Chrome is taking a long time to start, it may be due to a combination of low RAM and low space on the system hard drive partition (on drive C), it's worth trying to clear it up.
  • Second point, also related to startup - some extensions in the browser are already initialized at startup, but in the task manager in Chrome already running they behave normally.
  • If the pages open slowly in Chrome (assuming there is nothing wrong with the Internet in other browsers as well) - you may have turned on and forgotten to turn off some VPN or Proxy extensions - the Internet is much slower through them.
  • Also note: if, for example, something on your computer (or other device connected to the same network) is actively using the Internet (such as a torrent client), this will naturally cause the pages to open more slowly.
  • Try clearing the Google Chrome cache and data, see How to clear the browser cache.

As for the Google Chrome extensions, most of the time they are the cause of the slowness of the browser (as well as its crashes), and it is not always possible to "catch" them in the same task manager, so one of The methods I suggest is to try to disable all extensions (even the necessary and official ones) without exception and check the performance:

  1. Go to the menu - advanced tools - extensions (or type in the address bar chrome: // extensions / and press Enter)
  2. Disable all Chrome extensions and apps without exception (even the ones you need 100%, we do it temporarily, just to check).
  3. Restart the browser and see how it behaves this time.

If it turns out that with the extensions disabled the problem has disappeared and the brakes are no longer there, try enabling them one by one until you identify the problem. Previously, Google Chrome plugins could cause similar problems and could be similarly disabled, but control of plugins has been removed in the latest versions of the browser.

In addition, the performance of the browser can be affected by malware on your computer, I recommend that you perform an analysis with special tools to remove malware and potentially unwanted programs.

One last thing: if the pages open slowly in all browsers, not just Google Chrome, in this case you should look for the causes in the network and system settings (for example, make sure you don't have a prescribed proxy server , etc., you can read more about this in the article Pages do not open in the browser (even if they open with a squeak).
