Boot disk 100 windows 10 system. Disable MSI mode. Incorrect operation of AHCI drivers

Disk is the bottleneck in performance modern computers... All the main components of the "hardware" have long had a power potential, which "rests" on performance disk systems... Somehow this problem is solved by the latest solid state drives-, but even they sometimes cannot provide fast work systems.

Microsoft Developers Failed Algorithms latest version Windows and made a system that cannot efficiently use the hard drive.

Why is the disc 100 percent loaded?

Someone has a hundred, someone not 100%, but the fact is obvious - Windows 10 often "slows down" and freezes precisely because of the disk load. This condition occurs due to some of the services that are used in this OS.

There are several probable reasons for this:

The search service indexes all files on the hard drive in order to find it as quickly as possible if necessary required users files and folders. So, during indexing, the system accesses the hard disk too actively.
Superfetch service. Allows Windows 10 to somehow "cache" the applications you run most often. And this kind of allows it later with re-launches turn on programs faster. To do this, it monitors everything that happens in the system, writes something somewhere, and strongly "rustles" the disk.
Windows Defender - Defender. This is also a system service. Performs all kinds of scans in search of malware... It usually does not load the disk by 100%, but by 30-40% it is easy. Check settings are specified in the scheduler.

What to do if Windows 10 disk is loaded?

You can try to look for some "correct" solutions that do not affect system components, but I do not believe in that. Since the very first versions of Windows, it has always been necessary to do a lot of additional settings so that the computer does not slow down. And I believe that Windows 10 also needs a similar "tuning". If the developers make crooked decisions, you just need to stop it.

Disabling services due to which the system slows down and the hard disk is loaded

So, everything is simple here. You need to open service management and disable the alleged problem services

Windows Search

First, you need to launch the Service Management snap-in. There are many ways to do this, but the simplest and my favorite is through the "Run ..." dialog, which can be quickly called up with a keyboard shortcut win + R

The snap-in is called by the command services.msc

Why am I using this method? Because windows developers from version to version can change the location of menus, control panels, settings and other graphic elements. But console commands and the system kernel utilities remain unchanged. Therefore, instead of looking for where to enable this, I simply run the snap-in with this command. Saving time and effort leveled the 80th, friends :)

In the window that opens, find the Windows Search service in the list and double-click on it to open the control dialog for it. You can of course just press the "stop" button in the left upper corner or in the dialogue itself. But this will only help for the duration of the current session. And when you restart, the service will be started again, because by default the automatic start at system startup. In order to change this behavior, you need to set the state to "disabled" and click "apply" or "ok". Then, on subsequent starts, the service will not be started and will not affect the disk load.

Superfetch

Everything is the same here. In the same window, change the service settings.

Windows Defender

Here is a separate conversation. It is better not to disable this service. But you can change its settings in Windows Scheduler 10. The point is that the service periodically starts scanning files. Removing a task from the scheduler or changing its settings can help reduce the impact of this service on system performance. At least I managed to achieve a positive effect.

So, we launch the snap-in taskschd.msc in a similar way through Win + R and find there on the left in the Windows Defender tree. He has several tasks. Only scanning makes sense to touch.

You can try to remove it completely, if you are sure what you are doing, or you can change the settings.

At a minimum, you can change the setting to turn off a process if it takes too long. By default, this value is 3 days! This means that the scan can take 3 days before the system forcibly stops it. Imagine how the computer can slow down all this time. Therefore, I reduced this value to one hour. If the service does not cope with the planned task in an hour, the OS kills the process, and the decrease in performance will be for a maximum of an hour.

Windows 10 disk check

Many guides recommend using SFC / SCANNOW and CHKDSK / R... These methods can really help if disk loading is related to errors in file system... However, this may only be a temporary solution. If you are faced with such a situation, you need to do SMART check disk. It is a self-diagnostic tool for the drive. Perhaps your disk will soon stop working and you just need to replace it. If so, then SMART will show it.

Disk replacement

It may be that your drive is really worth replacing. In this case, I recommend considering the option and for replacement.

Since I started using Windows 10, I have faced one problem - downloading hard disk 100%. No, of course not 100% permanently. But it didn’t go below 90%. At first I thought it might be due to video processing programs. But after a while I realized that even during the idle time of the computer, when the load on the processor does not rise more than 10%, the hard disk continues to be used at 100%.

The percentage of hard disk utilization can be viewed in the task manager. To open it, right-click on the taskbar. The "Processes" tab allows you to see detailed information about the load on the processor, memory, hard disk of your computer.

Disable Windows Search

The first thing you should check is the service Windows search(Windows Search). Windows Search indexes content, caches file properties, Email etc. All of this makes it easy to find the content you want. Search by given parameters saves a lot of time. And Windows Search offers useful function for quick launch programs and document search, change system settings operating system.

Despite all the advantages, this service has its drawbacks. These are the so-called "search loops". The service starts indexing over and over again, going through the same files over and over, over and over, causing a high load on the hard disk. This, in turn, leads to an increase in the access time for system and third-party programs... I'm not sure if Microsoft is going to solve this problem somehow. All we can do is disable this service.

First, open the Run window. To do this, click the "Start" menu -> "Run" or the keyboard shortcut "Win + R". In the window that opens, enter the command:

services.msc

In the opened window of the list of all installed services, we find the service "Windows Search" we need. We click on it with the right mouse button and select "properties" in the context menu that opens. In the properties, stop the service and disable it. An indication that you have disabled the service - the start / stop buttons for the service will become inactive.

The service has stopped. I propose, without delaying for a long time, to look at the load of the hard disk in the task manager. As we can see, the load has dropped. Already good, but not perfect. Let's move on to the next idea.

Disable Superfetch service

The Superfetch service is a system service. It runs inside the svchost system process. The service includes a file caching mechanism. This mechanism is used to cache the most commonly used application files in RAM, which speeds up their subsequent launch.

Unfortunately, the service does not always correctly determine which program you use often and therefore can store cached files in RAM for a long time, loading and unloading them, thus slowing down the hard disk.

Disable the service. Make sure the service is stopped before disconnecting.

Disable Windows 10 Tips (Windows 10 Tips)

The two services we disabled above should have already improved the performance of the system as a whole. But if you don't see any improvement, try disabling Windows Assistant... Select Settings & Notifications and turn off Show me Windows tips. These actions will not take long.

Conclusion

But still. If the recommendations given by me did not help you, most likely it is not the operating system itself. You may have viruses on your computer. Check the hard drive with some anti-virus scanner or reinstall the system. But again. Reinstalling your system is a last resort.

Per recent times Windows users often encounter incorrect operation of the hard drive. Overloading is the most popular reason. The system slows down the speed, and the task manager shows the disk load at 100%.

In order to understand what is the cause of the load on the hard drive, you need to arrange the processes according to the degree of influence on the system and determine which of them is the most resource-intensive.

To do this, in the task manager itself, you need to click on Disk until the arrow points down.

After that, you can see which process uses disk resources more than others and may be the reason for the incorrect operation of the hard drive.

There are a lot of processes that can cause this problem.
And to fix this one can use different methods... Let's take a look at the most common ones.

To do this, we will divide them into groups and study each separately.

Windows Internal Services Failure
Disk problems
Malicious programs

Failure of internal Windows services.

Services Windows (Services) manage all processes in the operating system. These are services that can run in automatic mode when you turn on your computer, they also enable third-party programs to run. Since a specific service is responsible for the operation of an application, if it does not work correctly, the system may begin to malfunction. Incorrect operation of services such as SuperFetch, Windows Search, service Windows updates and service Reserve copy are the most common reasons for a hard drive.

Let's consider what these services are, where they are and how you can turn them off.

Before disabling certain services, be sure to familiarize yourself with what this service is responsible for, and what the consequences will be if you disable it.

SuperFetch.

The SuperFetch service detects which programs are launched most often, puts a mark on them about frequent use and loads them in advance. virtual memory... Thus, this service periodically accesses disk resources and can cause it to load.

In order to disable it, you need to:

Windows Search.

Windows Search is a service that enables users of the system to quickly find the documents and files they need. To do this, it periodically performs background scans of the contents of the user's computer. For quick search the service uses a file indexing system, which also makes it possible to limit the load on the hard drive.
In order to disable it, you need to follow the same procedure as disabling the Superfetch service.

Windows Update Service.

Windows Update allows developers to improve an existing system - improve security, streamline processes, add new features. Due to the fact that the Windows operating system puts a high priority on this service, during the system update process, less resources are allocated to other programs and they can slow down their work. But if you need resource-intensive programs for work, then using them in parallel with an active update process can cause a limiting use of disk resources.

To ensure that the update process does not interfere with the daily use of the computer, you can set up a manual update check. Disabling updates completely is strongly discouraged for security reasons.

Backup service.

The backup service is an operating system application. Using archiving tools, creates backups user information. This is necessary for system recovery if a critical error or virus infection occurs. Backups are very resource intensive and can also cause significant disk usage.

In order to change the parameters of this service and make it work when it does not bring us inconvenience, you need to do the following:

If you can see in the task manager that another service caused 100% Windows boot, then, by analogy, through the list of services, you can disable any of them. But you need to understand that this is a temporary solution, and if you may need this service in the future for your work, you need to analyze in more detail what it fails and restore the normal functioning of the system.

In some cases, for complete shutdown services and making changes to the system, you need to restart the computer.

Disk problems

The reason for the long loading of the hard drive in idle mode may be the hardware of the computer, or problems due to its interaction with other components of the system. The most common reasons are the following - physical damage to the hard drive, conflict or lack of drivers for the hard drive to work with Windows, and high disk fragmentation.

Physical damage to the hard drive

When physical defects appear, the performance of the drive is greatly reduced. Winchester can no longer process the data that the system gives it to him at the same speed. Because of this, the load on the disk is greatly increased.

You can use the built-in command to check the disk chkdsk.exe.

We are interested in the string - the number KB in bad sectors... If the value is different from 0, then you need to start the recovery process, either using the same command, or using third party applications such as Victoria, MHDD.

If the recovery of bad sectors did not help, then you need to replace the hard drive.

Lack of drivers

Many users who produce reinstalling Windows on their own, as a rule, do not pay attention to installing drivers SATA type AHCI. In most cases, the built-in Windows driver is enough for the disk to work correctly. But, if after disabling the services, the problem with loading the disk and slow work system continues, try installing or updating this driver.

In order to check for the presence of a driver of the SATA AHCI type, you need to look at its name in Device manager

We also go to Execute and use the command devmgmt.msc

Name - " Standard SATA AHCI Controller"Indicates that the system has a built-in windows driver... In order to install the necessary original driver, visit the website of the hardware manufacturer and download it from there.

The official driver from the manufacturer must ensure the correct operation of the hard drive with the system.

Updating computer configuration

Updating the computer configuration sometimes also causes incorrect work hard drive. This is especially true for cases with the purchase of a new carrier.

In this situation, if installing the drivers did not solve the problem. You can try to reflash Bios for more new version or reset its settings.

Fragmentation of the hard drive.

Fragmentation is the process of logically separating files. In case of fragmentation, a new file that needs to be written to the system is partially overwritten in place already deleted files and partly to a new location. If the system is highly fragmented, it needs more time to collect information and work with it, and the load on the disk increases accordingly.

In order to reduce fragmentation, defragmentation is used. A process in which parts of a split file are moved so that they are located on adjacent areas on the disk.

To start defragmentation, you need to go to Properties local disk, in the tab Service select Optimization

Active use of the paging file

The operating system begins to actively use the paging file when it runs out of physical RAM. Windows partially puts in it programs and services that are open in the background, but not in use right now. Such active work with the paging file can seriously load the hard drive.

You can see how loaded the paging file is standard means Windows. By using Task manager go to Resource Monitor, then click on the icon " Memory", Here you can see how much paging file is being used now.

If this indicator is constantly at a high bar, you need to stop the resource-intensive application in order to offload the paging file. Or, if you need to use more RAM for work, the best solution will be purchasing additional memory kits. This will take the load off the disk when accessing the paging file.

Running resource-intensive applications

Using resource-intensive programs such as torrent or sync apps cloud services, at the time of its active work can heavily load the hard disk.

You can also find out which program loads the hard drive very heavily using Task manager.

V this example you can clearly see how downloading and distributing torrent files puts a load on the hard drive. The same result will be at the moment when the application on the desktop is synchronized with the cloud. Examples can be listed for a long time, but the principle of operation is the same.

Here the recommendations can be as follows.
During active work with a computer, when large system resources are needed, disable all unnecessary applications for operation. It is best to continue downloading, torrenting and syncing when the computer will be used in multimedia mode.

Malicious programs

The actions of malicious programs can also cause maximum load on the hard drive. Recently, in addition to classic viruses, infection methods aimed at unauthorized mining have become very popular. Mining viruses are directly aimed at using system resources for cryptocurrency mining.

See a separate article about the newfangled ones and how to deal with them.

Define this process can be done in the same way - through Task Manager... If the first place in terms of impact on the disk is a process with an unknown name, which the user did not start on his own, and after trying to terminate it manually, the system refused, it may be a virus.

In this case, you need to scan your computer with antivirus solutions with up-to-date anti-virus databases to more accurately identify the latest malware developments.

Friends, we have considered the most popular reasons for 100% disk loading. If you know other methods for solving this problem, share in the comments.

Reason 1: Service "Windows Search"

For searching required files located on the computer, a special service is provided in the Windows operating system "Windows Search"... As a rule, it works without remarks, but sometimes it is this component that can cause a heavy load on the hard drive. To check this, you need to stop it.

Now we check if the problem with the hard drive is resolved. If not, we restart the service, as disabling it can greatly slow down the Windows search function.

Reason 2: Service "SuperFetch"

There is another service that can greatly overload HDD computer. "SuperFetch" appeared back in Windows Vista, she works in background and, according to the description, should improve the performance of the system. Its task is to keep track of which applications are used more often, mark them, and then load them into RAM, making them launch faster.

In fact, "SuperFetch" useful service, but it is she who can cause a heavy load on the hard disk. For example, this can happen during system startup, when a large amount of data is loaded into RAM. Moreover, programs for cleaning HDD can remove from the root system disk folder "PrefLog", where data about the operation of the hard drive is usually stored, so the service has to collect it again, which can also overload the hard drive. In this case, you must disable the service.

Open Windows services (use the method described above for this). In the list we find the required service (in our case "SuperFetch") and press "Stop".

If the situation does not change, then, given the positive impact "SuperFetch" to work the system, it is advisable to start it again.

Reason 3: CHKDSK utility

The previous two reasons are not the only examples of how standard Windows OS tools can slow it down. In this case it comes about CHKDSK utility which checks the hard drive for errors.

When the hard drive has damaged sectors, the utility starts automatically, for example, during system boot, and at this moment the disk can be loaded to 100%. Moreover, it will continue to run in the background if it cannot eliminate errors. In this case, you will either have to change the HDD or exclude the check from "Task Scheduler".

Reason 4: Windows updates

Probably, many have noticed that during the update, the system starts to work slower. For Windows, this is one of the most important processes and is therefore usually given the highest priority. Powerful computers they can handle it with ease, but weak machines will feel the load. Updates can also be turned off.

We open Windows partition "Services"(we use the above method for this). Finding a service Windows Update and press "Stop".

Here you need to remember that after disabling updates, the system may become vulnerable to new threats, so it is advisable that a good antivirus is installed on the computer.

Reason 5: Viruses

Malicious programs that got to your computer from the Internet or from external storage, can cause much more damage to the system than just interfere with normal work hard disk. It is important to track and eliminate such threats in a timely manner. On our website you can find information on how to secure your computer from different types virus attacks.

Reason 6: Antivirus program

Anti-malware programs, in turn, can also overload your hard drive. To verify this, you can temporarily disable the function of its check. If the situation has changed, then you need to think about a new antivirus. It's just that when he fights a virus for a long time, but cannot cope with it, the hard drive is under a heavy load. In this case, you can use one of the anti-virus utilities, which are designed for one-time use.

Reason 7: Synchronization with cloud storage

Users familiar with cloud storage know how convenient these services are. The sync function transfers files to the cloud from a specified directory, providing access to them from any device. During this process, the HDD can also be overloaded, especially when it comes to large amounts of data. In this case, it is better to turn off automatic syncing in order to do it manually when it is convenient.

Reason 8: Torrents

Even now popular torrent clients, which are ideal for downloading large files at a speed significantly exceeding the speed of any file sharing service, can seriously load a hard disk. Downloading and distributing data greatly slows down its work, so it is advisable not to download several files at once, and most importantly, disable the program when it is not in use. This can be done in the notification area - in the lower right corner of the screen, by right-clicking on the torrent client icon and clicking "Exit".

The article listed all the problems that can lead to a full load of the hard drive, as well as options for their elimination. If none of them helped, it might be the hard drive itself. Maybe it has too much broken sectors or have physical damage, which means that he is unlikely to be able to work stably. The only solution in this case is to replace the drive with a new, efficient one.

Users who have been working with a computer for a long time have more than once faced the problem of 100% load on the hard drive. This can happen in any Windows versions... Therefore, in the article I will tell you why the disk can be 100% loaded in Windows 10, and what options are there to fix the problem.

Hard disk boot reasons

There are many reasons and can manifest themselves in several at once:

System update.
Services Windows systems Search and Superfetch.
System processes svchost and system.
Disk fragmentation.
The presence of bad sectors.
Process loads of third-party applications.

First of all, pay attention to which processes are loading the disk by 100%. Based on this, it is easier to identify the malfunction:

How to fix the problem

System update

A common cause of the problem can be downloading updates. In the Task Manager, in the "Processes" tab, the Host of the services responsible for updating can load the system. If it's Windows Update, just wait for the update to finish. To prevent the OS from downloading updates every time, as soon as they are released, you can postpone updates:

If you have configured the backup function in Archive Services, the data copying processes can load the disk. To change the backup options:

Windows services and processes

At times, the OS services themselves can load the hard drive.

Windows search engine

The Windows Search service is responsible for searching and indexing files. The processes of this service are called SearchIndexer.exe and Searchfilterhost.exe. There are times when search system loops and observes loading hard disk by 100%. Reboot and new search do not save the situation. In this case, you need to manually disable the malfunction:

If the load has decreased, then the cause has been eliminated and no more action is needed. Over time, if the disk load appears again, you need to completely disable the service. The appearance of such a malfunction is typical when a computer is used old hard disk or there are problems with indexing files. To disable:

Advice! With the service disabled, you will not be able to search in File Explorer. However, disabling the service will reduce the load on the system, which will be useful for older PCs.

Superfetch service and svchost process

The Superfetch service is used to maintain and improve system performance. The service runs inside the svchost system process and monitors which applications you use most often in order to preload them in system memory... In addition, the service is responsible for the process.

With this functionality, frequently used applications load faster. But for preloading programs, the service consumes a lot of resources and can load the hard disk. To disable:

If svchost continues to load the system even after restarting the PC, see the material:.

System process

If a significant load falls on the System process, and disabling the aforementioned services did not bring any results, it is possible that the process simply does not have enough permissions.

It is difficult to determine how the rights of the ntoskrnl.exe file (the kernel of the operating system that starts the system process) and the disk load at 100% are related, nevertheless, it can help. To add rights:

Important! Check how the processes are behaving in order to find out if the problem is caused by a third party application / service.

Viruses

It should not be ruled out that your computer has been infected. In the Task Manager, in the "Details" tab, define the "Username". System files"System", "svchost", etc. must be signed: SYSTEM, LOCAL SERVICE, NETWORK SERVICE. If they are signed with your username, I recommend checking Windows 10 for viruses. Both free and free scanners like Dr.Web CureIt! or Kaspersky Virus Removal Tool.

Hardware part

The fault of the prolonged load of the hard disk in idle mode may be the very hardware of the computer or laptop. This could be:

If you have any questions or any points from the article are not clear, write about it in a comment. I and other users of the Windows 10 operating system will try to help.
