Boot disk 100 windows 7 solution. What to do if there is a large load on the disk. The hard drive is fully loaded: causes and solutions. Removing unnecessary software from startup

Every person who is trying to figure out why his computer is slowing down first looks at the “Task Manager” information. And almost always the result is the same: the disk is 100% loaded. It just so happens that the hard drive is often the slowest computer device in the overall performance system. In addition, it can partially take over the responsibilities of RAM, and this slows it down even more. Fortunately, the situation can be improved for the better.

Causes of disk load in Windows 10

The reasons why the disk is loaded to maximum? quite a bit of. The main one is the process repeatedly accessing files on the hard drive. These can be either external irritants (viruses, miners, and other malware) or internal ones: the operation (scanning) of Defender or another antivirus, an overloaded page file, incorrect operation of drivers, damaged sectors or files, an overly fragmented infrastructure, and much more.

Programs and processes that may be actively using the disk

Windows also likes to fully load the disk. In the system itself there are a lot of processes that from time to time consume a lot of hard drive resources. In addition, if you are running a decent game that weighs more than 2 GB when unpacked, this can also put a heavy load on the disk.

The main processes that can temporarily consume all the capabilities of the HDD:

Windows Modules Installer Worker - the process of downloading and installing Windows updates;
Antimalware Service Executable - Windows Defender can significantly load the disk during system scanning;
System - oddly enough, the system itself can access files in a demanding manner;
“Explorer” - while copying or deleting information;
"Service Host Local System" - includes a huge list of processes, including the firewall, user accounts and much more. Loads the disk temporarily;
games and much more.

Some processes can place a large load on the hard drive

What to do if the disk is 100 percent loaded in Windows 10

I would like to clarify right away that it will not be possible to completely and permanently remove the load on the disk. The hard drive has this job: to read and rewrite files, and these processes use its resources. The first thing to do if you see an unreasonable load on the hard drive and the situation does not change for a long time is to restart the computer. Perhaps a process is stuck in the page file or another reason is consuming a lot of HDD resources, restarting may help. And if the situation repeats itself after a little time, some measures need to be taken.

Disabling the page file

The page file is a very important element of computer operation. It performs several tasks: it stores some operating system data, in particular sometimes the OS kernel, and also acts as a “magic wand” for RAM, taking away some of the data that is stored there for a long time. This is actually a caching process to make your PC more productive. But sometimes there is too much data in the paging file, and the computer, instead of working quickly, begins to freeze. The page file, although not recommended, can be disabled.

In the search, enter “View Settings” and select the best match. In the search, enter “View Settings” and select the best match
In the performance settings window that opens, go to the “Advanced” tab and click the “Change” button. In the performance settings window, go to the “Advanced” tab and click the “Change” button
Uncheck the “Automatically select…” item, move the toggle switch to “Without a paging file” and save the changes with the OK button. Uncheck the “Automatically select…” item, move the toggle switch to “Without paging file” and save the changes with the OK button
For the changes to take effect, reboot the computer.

Disabling file indexing

Indexing files helps you find data on your computer faster. But if search is rarely used, then indexing should be disabled:

Canceling indexation can take quite a long time. It all depends on the number of files on the partition. In addition, there are files on the system disk that cannot be de-indexed, so you need to monitor the process to take appropriate action. In the author's memory, the procedure once took about an hour.

Disabling SuperFetch and Windows Search services

Some services can also put a strain on your computer. For example SuperFetch and Windows Search. The first is responsible for caching applications, while the second is responsible for searching and indexing. In general, the calling of both services is optimization. However, caching sometimes gets your PC into a state where it is better to simply delete it.

Scanning with antivirus and various utilities

The problem of viruses and malware will never be eradicated from modern society. Protection technologies only keep pace with attack technologies, so the possibility of catching harmful program code always remains.

Useful antiviruses that get high ratings:

Kaspersky Internet Security;
Symantec Norton Security Premium;
Eset Nod32;
Malwarebytes 3.0.

Programs that look for malware:

Reimage;
Advanced Malware Protection and others.

AHCI drivers are not working properly

Advanced Host Controller Interface (AHCI) is a mechanism used to connect storage devices using the Serial ATA protocol, allowing for advanced features such as built-in command queuing (NCQ) and hot swapping.

Wikipedia
https://ru.wikipedia.org/wiki/Advanced_Host_Controller_Interface

AHCI is a technology that allows hard drives to work as they do - faster than their previous counterparts. At the same time, the technology requires up-to-date drivers, otherwise the device buses will transmit information slower than possible.

Right-click on the “This PC” icon and select “Device Manager” from the drop-down menu.
Right-click on the “This PC” icon and select “Device Manager” from the drop-down menu
Open the “Controllers” tab, right-click on the device that contains AHCI in its name and select “Update Driver”.
Open the “Controllers” tab, right-click on the device that contains AHCI in its name and select “Update Driver”
Next, click “Automatic search and driver installation” and wait while the wizard downloads and installs the latest software.
Click “Automatic search and installation of driver” and wait for the wizard to do its job
Reboot the computer for the updated configuration to take effect.

Error correction

Disk errors can unnecessarily load the hard drive. If you access a damaged file or sector, the computer may even freeze and display a BSOD error. The best option for fixing errors is the standard check disk utility, which is launched from the command line.

Disk Defragmenter

Fragmentation is a method of writing data to disk that Windows uses. If a file cannot be written in one place, it is split into fragments and written to different sectors. Subsequently, access to the file will be slowed down, since the system will first have to “glue” the file together and only then read it. The defragmentation process allows you to overwrite files on a disk in a row as a whole.

If the disk loads 100%, it's not so scary. It is enough to reduce the load on it, disable unnecessary services and processes. This will save your PC from freezing and extend the life of your hard drive.

Today in this article we will look at ways to solve one very unpleasant problem, which manifests itself in excessively high load on the hard drive (HDD) or solid state drive (SSD). Users of computers running Windows encounter such anomalous system behavior quite often, and recently I had to look for ways to solve this problem. In particular, at some point my Windows 10 laptop started freezing and not responding for minutes. Having opened the Task Manager, I discovered that the SSD disk load reaches 100% even when idle, and for no apparent reason.

According to the Microsoft engineer whose advice ultimately helped me solve my problem, on some systems the culprit may be the Message Signaled Interrupt (MSI) mode - it is enabled by default. Some may not complete I/O operations successfully when MSI mode is enabled. By waiting indefinitely for unresponsive reads or writes, the Windows storage stack begins attempting to reset the disk device. It is these reset attempts that lead to Windows starting to load the disk at 100% and, therefore, the system stops responding.

The issue can be resolved by disabling MSI mode for the Advanced Host Controller Interface (AHCI).

Step 1: First we need to open the Device Manager snap-in. Press the + R keys and enter the command devmgmt.msc and press Enter.

Step 2: In the Device Manager window, find the “IDE ATA/ATAPI Controllers” node, expand it and open the properties window of the standard SATA AHCI controller.

Step 3: Go to the “Driver” tab, click “Details”. Now note that the Driver Files field should mention storahci.sys. If this is the case, then the SATA AHCI controller uses the so-called Inbox driver (certified by Microsoft, included with Windows), therefore, MSI mode can be disabled.

Step 4: Click “OK”. We return to the properties window, switch to the “Details” tab and select “Path to device instance” from the drop-down list. Save the value somewhere, we will need it later.

Step 5: Launch the registry editor with the command regedit.

Step 6: We follow this path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\ Controller valueAHCI\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties

"Controller valueAHCI» we received at stage 4 of the manual.

Now in the registry window on the right we find the parameter MSISupported, open it by double clicking the mouse and change the value from 1 to 0.

That's it, close the registry and restart the computer. After rebooting, the problem of 100% disk utilization should disappear.

What happened in the beginning?

Let's say you purchased a good, powerful laptop with the Windows 8 operating system. For some, it seems powerful, unlike Windows 7, for others, it’s the opposite. In any case, they say that it works quickly.

At first, this is indeed the case. You will work as usual, use programs, play games, and do other things. Everything will work quickly.

After several months of use, working on a laptop turns into hard labor. It takes a very long time to turn on, and you can’t wait for programs to start either.

Such signs may indicate that the disk is 100% loaded. To verify this, open the task manager and go to the tab "Performance" and see if the disk is loaded. If yes, then we will try to do something.

If the problem is not with the disk

If you're not sure if your computer's slow performance problem is related to the disk, try the following:

Check if the system disk is full. The main thing is that the stripe is not red.
To clean up garbage, we will use the CCleaner program.
We clean programs from startup.
Using an antivirus.
Try to remove suspicious programs that may overload the system.

We solve the loading problem 100%

When we went into the task manager, we may have seen that the disk is 100% loaded, but actually, where and what is it writing?

One of the problems is the innovation introduced into Windows by Microsoft. It is needed in order to.

This technology is called and is designed to quickly log into the system after sleep. This is done by writing information from RAM to .

Now it’s clear why our system is so slow and the disk is heavily loaded. But, as it turned out, this service can be disabled.

To do this we go to Control Panel and look for " Administration».

Now open the item “ Services" Scrolling and looking for a service Superfetch.

Right-click on it and click “ Stop».

For greater efficiency, right-click on this service again and go to “ Properties" Select the launch type " Disabled"so that the next time you start the system, the service will not turn on again.

Personally, when I went to the task manager, the disk load dropped sharply and was 0-20%. You can try turning on the Superfetch service again and make sure that the disk will boot to full capacity again.

Addition

I found out that some users contacted Microsoft support with this problem, but they just threw up their hands and said that nothing like this could happen. The system seems to be in perfect order. They also say that the problem is in the hard drive itself.

Thus, we still found the reason for the disk loading 100%, I think that this is not the only reason, but there are others that will be discussed and you can find out about them on our website.

Very often, after installing the Windows 10 operating system, users notice that the computer begins to freeze. Moreover, even in the absence of any heavy applications running, it is almost impossible to work with the system. At the same time, in the task manager you can see that the disk load is 100 percent. This happens not only on a new, clean system, but sometimes on one that has been working properly for some time. In this case, the user rushes to reinstall the OS. Sometimes it helps, and sometimes it doesn't. How then can you find out why Windows 10 loads the disk at 100%? I will give the most private and common reasons.

1. What application scans the disk?

This is probably the most common occurrence on both a clean system and an old one. On the old one more often. For example, the culprit behind such high HDD load is the UTorrent torrent client:

The program begins to rescan already downloaded files. If they are under a hundred gigabytes, then this can seriously load a computer or laptop.

An actively working anti-virus scanner can cause the same effect. To exclude this option, try pausing the antivirus application:

This is usually not observed on modern powerful PCs, but on old hardware, and even with a small amount of RAM, it does happen!

2. Indexing the hard drive by system services

In itself, the system file indexing service is a useful thing. As a result of its work, special indexes are created, which make it much easier for the system to search for files on HDD partitions. But here’s the paradox: few people use the search service. And it’s unlikely that an ordinary user will shovel the entire screw with its help. But the indexing process itself may be the reason why Windows 10 loads the disk at 100%. To eliminate this, first disable indexing in the properties of each section.

On the “General” tab, uncheck “Allow the contents of files on this drive to be indexed in addition to properties.” Click on the “Apply” button.

Now go to the “Computer Management” system console and open the “Services” section. Find the Windows Search service and stop it:

We look in the device manager to see if something is still loading the disk at 100 percent. If yes, then try stopping the service as well.

The point of the SuperFetch technology is also to analyze and collect statistics about the programs used. For the most frequently used applications, a cache is used in RAM, where their modules and libraries are stored in loaded form. It seems to be a necessary and useful service. But not always. Unfortunately, it can also cause the hard drive to overload. Try turning it off and see the result.

3. File system errors and HDD failure

File errors that appear on a hard drive can also cause abnormal brakes on a computer or laptop, and disk loading up to 100 percent is a consequence of incorrect operation of the drive. In Windows 10, there is a special utility to check the HDD for logical errors and fix them CHKDSK. To use it, open a command prompt with Administrator rights. Next, to simply check the logical partition for errors, enter the CHKDSK command and specify the drive letter. If you want the utility to find damaged sectors and correct errors, then you need to add the /F and /R keys. Here is an example of such a check for the C:\ drive.

Unfortunately, the cause of the problem may also be a physical malfunction of the hard drive. Here, the capabilities of standard operating system programs will not be enough and you will have to use additional specialized applications such as MHDD or Victoria.

4. SSD and ACHI mode

Advanced Host Controller Interface - AHCI is a special interface that allows you to get the most out of your SSD. If the mode is disabled, then after installing Windows 10 you may encounter the fact that the computer will barely move, and the HDD load will jump to the maximum.

The way out of the situation is simple - you need to go to the BIOS and the operating system settings. However, after this there is a high chance that it will have to be reinstalled. But after this, normal operation of the computer will most likely be restored.

5. Other reasons

Now let's look at less common reasons, due to which a situation may also arise when Windows 10 loads the hard drive at 100 percent.

One of these is the page file when using an SSD drive. The fact is that if you have a solid-state drive installed, then for it no swap file needed. Moreover, its presence can lead to problems. Therefore, we disable it completely. To do this, open Windows 10 Performance Options. On the “Advanced” tab, find the “Virtual Memory” section and click on the “Change” button.

Here you need to uncheck the “Automatically select the size of the paging file” checkbox and for each of the logical partitions check the “Without paging file” checkbox. Apply the changes and reboot the computer.

The second reason is perhaps defragmentation started hard drive and it was because of this that its load jumped to 100%. Here you can either wait until it works completely, or try to reboot.

There have been cases where the disk was 100 percent loaded because the user was logged in under Microsoft account. I don’t know what is happening at this moment, but the hard drive is loaded to its fullest.
To exclude this scenario, try creating a local account and logging in under it.

If suddenly you notice that the hard drive is loaded at 100 while the Google Chrome browser or any other browser running on its engine is running, then the reason for this may be the plugin is not working correctly Flash player. By disabling it in the program settings, you will be able to work normally with your computer again.
