The Yandex browser is loading the system. Google Chrome uses a lot of CPU: get rid of the miner CPU load reaches 100 when opening the browser

Let's figure out why the browser loads the processor at 100%. It could be Yandex browser, Opera, Google Chrome, Mozilla or any other. What's the matter? Why does the processor overheat when accelerating at full speed?

What is the reason?

There are more reasons than you might think. At the same time, some are easy to eliminate, while others can only be dealt with by a specialist. The power of the computer itself plays an important role in this process. Sometimes this is the determining factor.

The main reasons usually include:

📌 Opening a large number of tabs. If you are looking for something on the Internet and at the same time opening page after page, then the computer may not be able to cope with it. At some point it will start to slow down. The solution is very simple - close all tabs and you don’t even need to reboot. The processor will be restored. How more powerful computer, those more tabs you can open it at once, roughly speaking.

📌 Too many workflows. Look in the tray, or you can also go to the task manager (CTRL + Alt + Del). Sometimes there are a lot of tasks and active processes that you might have forgotten about. For example, a running game, keeper, even a heavy Excel file can overload the system. Complete at least some of them, and the load will decrease.

📌 Outdated browser version. If you haven’t updated for a long time and the previous points are not about you, try updating your browser to latest version. Download only from official source. To be sure, reboot after installation.

📌 Viruses. It is never a bad idea to check your computer for viruses. A standard run through the database will at least help eliminate this option.

📌 Extensions and plugins. Any browser has extensions for more convenient and complete work in it. Some of them may load the processor or interfere normal functioning. If you installed only official applications, there are fewer risks. To check this point, try disabling one application at a time and see how the computer behaves.

If unofficial plugins were to blame in your case, try to use only those offered at the following links: for Mozilla - addons.mozilla.org, for Opera - addons.opera.com, for Chrome - chrome.google.com/webstore.

When the reason is not in the browser

It happens that the reason lies not in the browser, but in the computer itself:

📍 Driver conflict. This happens when drivers are installed manually. For example, you might be using outdated or incompatible drivers. If you didn’t do anything yourself, then it’s unlikely that it’s them, but if you installed them, you probably remember which ones. By updating or eliminating them, you can see the solution.

📍 Negative impact of viralsvchost.exe. svchost.exe itself is not a virus! But the virus that imitates it - yes, it is dangerous for the system.

📍 External factors. As a last resort, check for dirt and dust in the computer. It may be too hot or the fan may be broken. Physical reasons They don’t happen often, but usually they make themselves known right away.

How to remove the load 100%

By studying the most common causes, you may have already figured out the problem, but if this is not the case, try the following step by step:

1. Delete cache, history, cookies in your browser. You can even reconnect the user.
2. Go to the “Task Manager” (in the tenth Windows versions Click on Start with the right mouse button and select the desired item in the menu that opens). Look in the “Dispatcher” for everything that loads the CPU and feel free to turn it off.

Now for individual browsers:

• Install FlashBlock. This is an application that is suitable for Google Chrome and Yandex Browser, it blocks scripts and unwanted programs.
• For Mozilla search bar enter about:config and write browser.cache.disk.capacity. Replace element 16384 by restarting the computer. In some cases, this also helps: enter about:config, write dom.ipc.plugins.enabled and change the files to false. Don't forget to reboot.
• For Chrome, you can also go to “Settings”, from there to “Advanced” - “Reset settings and remove malware”. Scan. By the way, if you follow the path C:\Program Files\Google\Chrome\Application\chrome.exe and there are more words at the end, then this is probably an infected version.

What else can you do?

Did not help? Then we act even more radically. You can take separate steps, or you can do everything at once, just to be sure:

• Please update your browser. Make sure to do it from the official website.
• Disable JavaScript. To do this, go to “Settings” - “Tools” and there uncheck the “Enable JavaScript” item.
• Install Sysinternals Suite, which needs to scan the Task Manager. The fact is that the standard “Task Manager” does not show the whole picture.
• Do a standard computer cleaning with using CCleaner. AdwCleaner and Dr.Web Cureit also help with this.
• You can disable auto-update. To do this, go to “Start” - “Control Panel” - “Administration” - “Services”, where we select “Center” Windows updates" - "Stop."

As a preventive measure, you can carry out a general Windows check. What can be done:

• Run command line(Win+R), write sfc/scannow there and wait for the process to finish. Using this option you can find broken files.
• For Windows 7, you can install Microsoft Fix it and use it to reset the network. Do it only if you understand what it is about.
• Run a cmd line and write netsh int ip reset logfile.txt, rebooting your computer.

So, we figured out why the browser loads the processor at 100%. At the same time, as you can see, it doesn’t matter whether the browser is Yandex or Chrome. In any case, start with the easiest and most obvious solutions, and they will certainly help. Share your experience if it worked.

Google Chrome, however, like any other browser, should not actively consume processor resources. An exception may be cases where the flash player works on very weak or old computers. On modern PCs and laptops with at least average performance, a processor load of over 90% can occur, but for this, resource-intensive tasks such as 8K/4K video playback must be running in Chrome. If 8K/4K video is not played in Chrome, some powerful browser game is not running, and other operations of comparable resource consumption are not processed, but the Windows task manager shows that the processor is loaded almost to the limit by the browser, someone is probably and enriches himself at your expense. How to get rid of a miner in Chrome?

Google Chrome uses a lot of CPU: get rid of the miner

So, in the Windows task manager we see how the browser loads the processor almost to capacity.

On the Chrome support site itself, in such cases they recommend:

Clear the history;

Update to the latest browser version;

Scan your browser using the built-in malware search engine.

The first two options will help in very rare cases. Finding malware will probably solve the problem.

But only if it can find malicious codes. Built in Chrome tool The malware scanner itself periodically scans the browser in the background, and if it had found something, it would have already notified us about it. It is not a fact that hidden miners within extensions or on sites open in the browser will be detected as malware. You can run a scan installed in Windows environment antivirus or special utilities to search for potentially dangerous software like AdwCleaner. But here, too, success will not be guaranteed in every case. The miner hidden in the browser can be calculated as follows.

How to detect a hidden miner in Chrome

Launch the Chrome task manager using the Shift+Esc keys. Click on the “CPU” column to build a list of processes in descending order. In our case, the first and most actively using the processor resource is a certain process “Subframe: https://staticset.com/”. Double click on it.

So, we have discovered the culprit of the active consumption of processor resources. If this is a tab of some site, close it. If it's an extension, let's first disable it.

Now we test Chrome under different loads - we just open websites, launch videos and flash games. And we monitor the processor load in the Windows task manager. In our case, disabling the extension solved the problem. With the same active tabs, the processor is loaded by 5-10%.

Now all that remains is to go to the extensions section and remove Stop Ads.

Well, we simply forget about the site that dishonestly mines cryptocurrency.

How to protect yourself from hidden mining in Chrome

How to prevent the appearance of hidden miners in Chrome in the future? For these purposes, the browser store has special extensions such as MineBlock, No Coin and their analogues. You can resort to the level Windows type entering into hosts file a list of domains of well-known sites caught in mining. The disadvantage of any kind of methods of combating illegal cryptocurrency mining is that software for hidden mining and sites that make money from their visitors in this way appear every day. Where is the guarantee that the creator of some harmless extension, say, to implement a reading mode or customization home page tomorrow he won’t sell his soul to the devil and start making money from you? So not a single browser extension like “Anti-Miner”, not even a single antivirus with regularly updated databases will provide complete, 100% protection against this evil.

After using the system for a long time, it begins to slow down, and various kinds of problems arise that users are not always able to solve. One of the main reasons slow work The PC is at 100 percent CPU utilization. And it’s not always clear why this problem arises.

There are two reasons - hardware room And software. The second, of course, appears much more often, so we’ll start with it. There could be viruses, unknown processes, anything. In this article I will try to help you understand the CPU load at 100%.

If there is a suspicion that the processor is loaded at 100 percent

Go to Device Manager (keyboard shortcut Esc+Shift+Ctrl) and go to the tab "Performance". In the CPU section there is a graph that will let you know how much the processor is loaded, as well as a line "Usage". If the load is still 100 percent, then it is worth taking action.

Software type problem

When you open the task manager, you need to find the process that is using the processor. This can be done by any program installed on a PC, or by a virus. Perhaps you didn’t find anything worthwhile in the “Processes” tab, then go to the tab "Details", it shows all the running processes and try to find the one that is using the CPU the most. If you don't know what to complete, I recommend contacting an experienced specialist.

Of course, using the task manager it is not always possible to find the required process, then it comes to the rescue third party utility Process Explorer. Run it and sort the processor by load (CPU) and see what it gives us.

Sometimes, the real culprit of the load may appear, and then you can close it without problems, but there is another situation when it is the system process that is loading the CPU. Often this can be a process of system interrupts and getting rid of this is not always easy. Of course, sometimes a simple reboot helps.

System interruptions can occur for several reasons: viruses, problems with the hard drive and drivers, problems with printers, scanners and any other devices connected to the computer.

Drivers

You can check whether the reason is really in the drivers as follows: boot into safe mode and check the CPU load, if it’s not 100%, then the drivers are definitely playing pranks. You can try to remove the video card driver and check the load; if that fails, then you will have to remove everything altogether. Although this is a rather risky process, which ultimately still involves reinstalling the system.

Problem due to viruses

Viruses are capable of many things, and CPU usage is no exception. They can even hide under the guise of system processors, so regular user won't even understand. Try using several utilities to scan your PC for viruses, I will give several links to such programs and how to use them.

Hard drive problem

In general, this doesn’t happen often, but I’ll also describe this point to be on the safe side. Hard drives have two operating modes - DMA And PIO. The first involves working directly with RAM, while the second is outdated and uses the processor during operation. Naturally, if HDD works for you in PIO mode, then you need to switch. This article describes how to do this.

Peripheral problem

The easiest way to check if peripherals The culprits of CPU usage are to disable everything in order. Also, go to the device manager and check if drivers are installed on all devices. If a yellow triangle or a red icon is lit there, then due to the lack of drivers, such a problem may have occurred.

You can get to the device manager like this: press the keys Win+R and enter the command there devmgmt.msc .

If you see a lack of drivers on some devices, update them directly from the device manager, or use third-party utilities.

Hardware problems with CPU utilization at 100%

Dealing with hardware problems is a little more difficult than software problems, especially for an inexperienced user. But we will try.

A common cause of load is overheat. What do you think causes it? Most likely due to a poor cooling system or dust.

First, let's check with AIDA64 or any other similar processor utility. In AIDA64, open the tab "Computer" and go to the section "Sensors".

The optimal temperature for your processor can be determined on the manufacturer's official website. On average, of course, up to 40 degrees is normal. From 50 degrees and above already puts one under suspicion, and above 70 degrees indicates some problems. Of course, for some processors even 70 degrees is the optimal temperature.

In this case, it would be wise to check the CPU cooling system first. Open the computer or laptop case and, preferably, clean all components. For cleaning, use a brush and vacuum cleaner. Cleaning often is not necessary, but at least 2 times a year is necessary. We make sure to change the thermal paste on the processor about once every 3 years.

Of course, the described methods do not fully solve the problem with the processor. Hardware problems can even include damage to the processor, which is rare, but the only recommendation in this case is to replace it. This can be problematic on a laptop, since they often cannot be replaced. In general, explore and if you have questions, ask them in the comments.

Sometimes an extremely nasty situation happens when you realize that the system suddenly starts to slow down. And it seems like nothing is really running, except for the browser, in which, oh damn, there are several dozen tabs open. What to do? How to identify the one that suddenly began to devour memory and load the processor, accelerating the cooler to unimaginable speed and slowing down all other processes?

With so many open tabs in the browser, it is difficult to click through everything. And then, how can one outwardly determine which of them suddenly began to play pranks and mischief?

I really don’t want to close the browser or restart the PC and then wait for the whole heap to load again. Closing everything means saying goodbye to those tabs that you have just planned, but have not yet studied.

After all, everyone knows about the existence of the Windows Task Manager, which is called by the keyboard shortcut Ctrl+Alt+delete?

A similar thing exists in most modern browsers, at least those built on the Chromium engine. After all, many users today spend their day exclusively on the Internet, that is, in the browser.

You can call the browser process manager using the keyboard shortcut Shift+Esc. Or else:

• Menu - Additional tools - Task Manager (Chrome).
• Menu-Advanced-Additional tools-Task Manager (Yandex.Browser)
• Menu-Tools-Task Manager (Vivaldi)

In it you can see a list of processes inside the browser: open tabs, added extensions, system processes browser, which can be sorted by the amount consumed random access memory or by processor load. Then, if necessary, you can complete only what is causing inconvenience without closing the entire browser or touching unnecessary tabs.

Should I talk?

Mazay:
Thanks a lot!!! For the first time in a lot of years I learned about such a feature!

Zeleboba:
Mazai, we are very glad that the material was useful for you :)

Many users experience CPU or disk loads when running the browser. Basically, the loads are small, but there are times when the values ​​rise to 100 percent. This situation can be caused by either one active browser or any of the launched ones (Yandex, Google Chrome, Opera, Mozilla). Today we will tell you what steps you need to take first to reduce your load.

Causes

There can be many sources of such load. First of all, it’s worth saying about banal things - too a large number of active windows (in one we watch a movie, in another we process photos, a file is being downloaded, etc.). High loading is also caused by viruses (advertising Trojans, hijackers), which, in principle, are now focused on such applications. You should not discard the optimization of the system itself - an outdated build of Windows often begins to fail. In any case, there can be many sources, so it’s worth performing standard operations.

Fixing 100 percent load

Operations to reduce workload can be divided into two stages - simple and complex actions. Simple actions mean rebooting, cleaning, updating. Start with simple steps, although not all will be effective, they will certainly not be superfluous in optimizing work. If simple things like restarting the browser and PC do not help, you need to do the following.

Cleaning the browser and operating system

Checking the system parameters

Conclusion

If the browser still loads the processor up to 100%, you will need to remove it, apparently its packages are faulty somewhere. You can uninstall the program as standard and clean up residual folders in CCleaner (option Cleanup – Registry). You only need to download the new installation from official resources. In rare cases, your hardware simply no longer supports the configuration of such programs, so here you need to roll back the browser version to an earlier one. But the main thing to remember here is that older versions do not support many technologies (HTML5, video codecs, etc.).
