How to fix the error

Let's look at how you can quickly fix a problem if it occurs due to software failures - in the case of hardware errors, you will have to manipulate the equipment.

Driver Update

In most cases, an error caused by old driver versions occurs while the Internet is running - this indicates that the network card drivers need to be updated. Drivers can be downloaded manually from the manufacturer's website or installed using various third-party utilities - for example, DriverPack Solution or Driver Booster.

To manually update drivers, you need to find out the exact model of the network card. You can do this through the “Device Manager”:

1. Press the Win+X combination and go to the “Device Manager” item.
2. Find the “Network Adapters” section and expand it.
3. Copy the name of the network card and find drivers on the Internet by name.

Attention! If you use third-party software to update, then update all other drivers as well - this will help protect against errors in the future.

. Recovering system files

Recovering system files

Windows 10 allows you to check the integrity of system data using a built-in utility. To perform this procedure, you need:

1. Right-click on “Start” and launch Command Prompt.
2. Paste the command “sfc /scannow” into the line and press Enter.
3. Wait for the utility to complete.

After completing the check, you need to reboot the device.

Disabling Fast Startup

The fast startup option often causes a Kernel Power error. Disable this feature:

1. Open the “Run” window via Win+R and execute the “control panel” command.
2. Open the item “Hardware...”, go to “Power Options”, click on “Button Actions...”.
3. Click on “Change settings...” and uncheck the “Enable fast startup” checkbox.

Attention! After saving the changes, you must restart your PC.

Resetting BIOS Settings

If custom hardware settings are applied in the BIOS, they may affect the stability of the device. After all, fine-tuning the BIOS requires certain knowledge. It's best to return to factory settings.

1. Enter the BIOS according to the instructions.
2. Using the mouse, keyboard arrows or keys, click on the “Load Setup Defaults” or “Optimized Defaults” option. In some versions it may have other similar names.
   Read also:  How to add a program to startup: instructions for Windows 7
3. Confirm the action.

The PC will immediately reboot and start with the standard BIOS configuration.

If you don’t want to tinker with the settings, then there is another way to reset them. Turn off the power to the PC and open the case. Find the coin-type battery on the board, marked “CR2032” and carefully remove it from the holder for 10 seconds. Then put it back, close the lid and connect the power. The configuration will be reset.

Causes of Kernel Power 41 error

Specific causes of the Kernel-Power error event 41 (category 63) may be as follows:

• Problems with your PC's power supply (in particular, power surges);
• Physical damage to various PC power cables;
• Unstable operation of the uninterruptible power supply (UPS);
• Incorrectly working memory sticks;
• Incorrect operation of external devices connected to the PC (USB drives, etc.);
• The action of various software for overclocking a PC (overclocking);
• Simultaneous installation of two sound cards in a PC;
• Outdated drivers for computer components (in particular, network cards);
• System overheating (in particular, due to the fact that the computer’s cooling system is clogged with dust);
• Outdated BIOS version;
• Action of antivirus programs.
  Error in Windows

Checking the hardware

In passing, it should be noted that event code 41 may also indicate that the cooling system in the computer is malfunctioning, which can lead to overheating of the processor under increased loads. You should perform a stress test for it, using, for example, the Prime95 utility with the In-place large FFTs mode selected.

It is also worth checking the RAM, for which even the built-in Windows tool, called from the program launch console (“Run”) with the mdsched command, is a good idea, after which immediate testing with restart is selected. It is also strongly recommended to check the hard drive both for the presence of software errors or BAD sectors, and for physical wear.

In the first case, it is advisable to use the command line with the CHKDSK applet toolkit with the attributes “/x/f/r”. For the second option, it is better to turn to applications like HDD Health or HDD Life. Based on the test results, it will be possible to determine the actions taken to eliminate problems. If you don’t want to send your hard drive in for repair, try to restore its functionality using the HDD Regenerator utility, which, according to the developers, remagnetizes the disk surface and restores damaged sectors.

Symptoms of error 41

• The message “Error 41” appears and the active program window crashes.
• Your computer often stops working after displaying error 41 when running a certain program.
• “Windows 7 Error 41 Kernel Power” is displayed.
• Windows runs slowly and responds slowly to mouse or keyboard input.
• The computer periodically freezes for a few seconds.

These 41 error messages may appear during program installation, while a Microsoft Corporation-related program (such as Windows 7) is running, during Windows startup or shutdown, or even during installation of the Windows operating system

Keeping track of when error 41 occurs is important information when troubleshooting the problem.

Critical error Kernel-Power 41 Windows 10

As a result of Kernel-Power error 41, the system reboots, ending with errors. The event log description indicates the following possible causes for the error: the system has stopped responding, a critical failure has occurred, or the power has unexpectedly turned off. The event log describes the problem very specifically without helping the average user fix it. See also: .

Possible causes of a critical Kernel-Power error in the system include:

• The presence of old versions of drivers in the system that are not compatible with Windows 10. Often, after a clean installation of the Windows 10 operating system, users install the drivers that were supplied on the motherboard disk. The problem is more relevant for owners of old computers, since in most cases users try to install drivers that are designed for previous versions of the operating system. It’s just that when creating the motherboard, the developers did not optimize the drivers for future operating systems.
• Violation of the integrity of system files of the Windows 10 operating system. As a result of violation of the integrity of system files, some functions begin to work not entirely correctly. An example of incorrect operation of operating system functions is the fast startup function, which helps speed up the computer startup after shutdown. In the latest versions of the operating system, disabling fast startup may also help solve the problem.
• The problem is the compatibility or performance of individual computer components. Not all users can even guess about the incompatibility of their computer components. Since even after assembly, it may turn out that the processor is not entirely compatible with the motherboard, despite the fact that previously all sources indicated full compatibility. It’s also worth paying attention to the performance of the RAM, especially if you have several different sticks.
• The result of incompetent overclocking of computer components using any of the methods. Overclocking the system as a whole should be taken very seriously. After uncontrolled overclocking, a computer component may completely stop working, for example, due to an attempt to overclock on a weak motherboard or overheating of the components themselves. That is why overclocking of components should be carried out in parallel with temperature monitoring.

Solutions

The decisions are submitted in random order. There are situations in which checking and deciding are almost the same action. During testing, situations may arise that help the user troubleshoot.

Checking the power supply

It is possible that the power outage is due to the fact that when there is a load, the unit stops producing the standard voltage . This voltage can be measured normally only in a service center or if you have the necessary equipment (multimeter and 3-4 hard drives) at hand.

At home, you can try connecting a different power supply . If the computer starts normally, you should load it. Demanding games or special programs (FurMark or Aida64) provide a good load. If there is no problem, you can take the old power supply to a service center, where it will finally be declared non-working.

This method requires the presence of a spare power supply. Alas, such a thing is not always at hand. You can turn to friends for help.

File integrity

As a result of damage to some Windows files, Kernel Power 41 can occur. This is easy to check, but takes a long time. One of the advantages is the automatic operating mode. The user is required to:

1. Run command line (“Win+R” with text cmd).

2. Enter text: "sfc /scannow».

The Command Prompt must be run as an administrator for some OS versions. Also, you will need to wait quite a long time if the problem is really with the system files (they will be re-written).

BIOS Settings

The desire to get better performance accelerates the wear of hardware or disrupts its correct functionality. It is better to reset the BIOS settings to factory (by removing the battery from the motherboard while the computer is turned off) or change them to normal.

If there are such changes, it is better to set all parameters to Auto . The location of the “overclocking” functions completely depends on the version of the BIOS itself.

Required to enter BIOS. To do this, the PC is rebooted and when it just starts to turn on, you need to press the “ del ” button. In the utility itself you need to find the specified items, the location and availability of which varies depending on the BIOS version.

Sound card conflict

Problems with the sound card are an extremely rare case. If there is a built-in and discrete sound card on the motherboard, sometimes a peculiar struggle for sound control begins. This results in spontaneous computer shutdowns. Therefore, you need to remove one of the sound cards and check its functionality.

The integrated sound cannot be removed. It can only be disabled in the BIOS . In the “ Chipset ” or “ On- board devices ” section, such an option is present even on midi-towers of the HP assembly.

Registry fix

An extreme case, but a simple one. You can launch the registry editor (“Win+R” and the text “ regedit ”).

In the registry, through a search, you need to find the key: DeviceMetadataServiceURL.

Replace the text in this parameter with:

You need to create a backup copy in case the changes do not help. Changing anything else in the registry without proper knowledge is strictly prohibited.

Checking RAM

The Kernel Power error can also be caused by RAM. You can check it either using the special program Memtest, or using a standard Windows tool during computer startup. To call the checker you will need:

1. To restart a computer.
2. After initializing the BIOS (text about HDD detection), start pressing “ F8” .
3. In the boot options, select “ memory check ” or “ Memory diagnostics ”.
4. Configure the necessary scan parameters and run it (if there are critical errors, even a superficial test will report this). If there are no errors, the problem is different.

This method is actually easier than running a memory diagnostic tool or memtest. But the reliability here is only 75%.

Disable external devices

An alternative solution is to completely turn off all external devices. That is, you need to disconnect everything from the computer except the keyboard. And try to load it. If the error does not appear, then we begin to connect the devices back and so on until we determine that the combination of speaker + mouse or printer + modem causes the error.

The method is long and does not guarantee a solution to the problem. Usually it is necessary not only to replace the element causing the failure, but also to carry out diagnostics of the motherboard .

Driver Update

It is logical to assume that the failure may be caused by incorrect operation of the drivers. Therefore they should be updated. To achieve results you need:

1. Open Device Manager .
2. Select the device and open it "Properties».

3. Go to the "Driver" and select "Update».

Most often, updating the network card driver . Usually its failures cause this error.

Everything has to be updated, manually and with standard drivers. You need to update the video card driver using a proprietary utility . Nuances can be in the most unexpected places.

Temperatures

The last, but most important problem may be temperature violations. This usually triggers a power outage to maintain functionality. There are many monitor programs that check the temperature of various components.

For example, the Aida64 program has a “ sensors ” tab, which shows the degree of heating of certain components. Also in the service tab you can check the operation of the system under maximum load. If the temperature goes beyond reasonable limits, 2 further scenarios are possible:

1. Take your computer to a cleaner to change the thermal paste and put all the necessary components in order.
2. It's a rare case that fans stall . Then they do not provide enough cooling and require replacement.

Also, you should understand that Kernel Power 41 can occur as a result of the failure of some components of the motherboard. This can only be diagnosed in service centers.

Recommendations to correct the situation that has arisen

Naturally, it is always advisable to know in what cases a blue screen with the message “kernel power 41 63” occurs - this can help speed up the treatment procedure. For example, if it was noticed that this failure occurs when launching very resource-intensive applications, for example, graphics programs, games, and so on, then the root cause of kernel power (critical error 41) may be additional settings applied to the processor.

That is, its banal overclocking. To resolve the conflict you need:

1. Initiate PC restart.
2. At the initial boot stage, go to the BIOS (usually this is done by pressing the “Del” button).
3. Find the CPU configuration settings menu - in each BIOS version they can be located in different places.
4. Return all CPU parameters to their original state, that is, deactivate overclocking, acceleration and other additional loads on this piece of equipment.

How to fix kernel power 41 on Windows 7 and 10 if the first method did not help?

The following treatment methods are recommended:

1. If kernel power 41 appears in Windows 7 and 10 when there are two sound cards running in parallel, then it is advisable to completely disconnect one of them from the computer and check its performance for a while.
2. When launching online games, a blue screen appears - kernel power error code 41 - what is it? There is a high probability that the reason lies in outdated network card drivers. The solution is to update these files. To do this, follow the following path: “Start” button/computer/system properties/device manager. Then you need to find the network equipment in the list, right-click on it, go to properties, make sure that there is an Internet connection, and click on the button that allows you to update the drivers.
3. Critical kernel power error 41 may be caused by missing critical updates. Especially if the computer owner deliberately disabled their automatic search and installation. To fix it, go to: Start button/control panel/system and security/operating system update center. The next step is to change the settings of this application to automatically check for important updates and force the system to install them on the PC.
4. Perform a security check of system components. How to do it: click “Start”, go to “Run”, enter “sfc.exe”. Wait for the procedure to complete.

The last option is to check the functionality and relevance of all drivers. This can be done using special software from Microsoft included in the operating system. Initially, you need to log into the system with administrator rights, then go to the “Run” line and type “verifier.exe” in it. A utility window will open, where it is recommended that you select a full test of the relevance of all drivers from all the proposed actions.

At the end of the program, the computer restarts and if the utility finds a problem, the OS will display a corresponding blue screen with all the necessary data. You should understand which device is working incorrectly, restart the computer, press the “F8” key in the process, then enter in safe mode, go to the device manager and initiate reinstallation of the driver for the equipment that may be causing the conflict.

Checking operational boards

Another common cause of this error is the RAM board. If it is poorly connected or the input has a lot of dust. So, remove the side cover of the system unit and press out the clamps that are located at the ends of the board. We remove the board, shake off the dust and return the board back.

Of course, you need to disassemble the system unit with the power off. Then, turn on the computer. Let's look at its functionality. Next, we will use the system utility for memory analysis. Go to the “control panel” and select “Administration”. You can simply enter “Memory” into the PC search.

Then, you will see 2 links that will help you analyze your PC's memory. Next, the OS will ask whether you want to restart the computer now or perform an analysis during the next startup. We choose the first option.

During boot, the OS will begin to analyze. It consists of two points. The “Status” line will appear at the bottom of the screen, in which you will see any errors found. During the test, you can click on the F1 button and change some of the settings, such as the test type. It can be basic, standard or advanced. You can also configure the cache and hop count.

What does error 41 Kernel-Power category 63 mean?

First, a few words about what this failure is. As a rule, its occurrence is accompanied by the appearance of a blue screen.

But in the description there is no mention of error 41 Kernel-Power, and instead of it, the line “KERNEL_DATA_INPAGE_ERROR” is presented at the top, and at the bottom there is a link to the faulty file, which is usually the device driver. However, the driver may have absolutely nothing to do with it, and information about the failure is presented only in the above-mentioned event viewer section. It is believed that the occurrence of this problem is associated with sudden power surges. But this is not always the case. Typically, this error can be interpreted as a situation associated with damage to some hardware component, which places too high a load on system resources, the capacity of which is simply not enough to process all active processes. In this case, the system freezes so seriously that no action helps. You only have to use forced shutdown by long pressing the power button. But even during the subsequent boot of the system, error 41 Kernel-Power may appear again. And this especially often manifests itself when launching modern resource-intensive computer games.

Update your drivers

The problem occurs if the drivers are outdated or incorrectly installed. It often appears when opening resource-intensive games. What to do? Press “Win+R”, enter the command “verifier”.

Activate the checkbox next to the “Non-standard parameters” item:

Next, check the boxes next to all items except two:

ABOUT:

A. Restart your PC. After turning it on, the scan will start. If there are problems with the drivers, a “Blue Screen” will appear on the screen, where the error and the name of the file associated with it will be displayed. Write it down and look for information about it on the Internet. It will be known which device driver is not working. Install or uninstall it. If the error does not appear on the screen, perform an additional check. To do this, in the window of drivers being checked (described above), o. Driver information will appear. Check all where the suppliers list is not Microsoft Corporation.

Restart your PC. Review the BSOD information.

Install drivers from the official website of the equipment manufacturer.

Uninstall and reinstall by opening Device Manager. Press “Win+X”, then:

Open the hardware group for which you need to update the driver. Next: Open the driver you downloaded earlier and install it following the instructions.

How to fix Kernel-Power error 41 in Windows 10

Updating old drivers

If an error occurs while working at a computer using an Internet connection, we recommend that you first update the network card drivers. This is especially true for users who bought a computer several years ago. Since the disk for the motherboard only contains the old version of the drivers. And you will have to download network card driver updates yourself.

Since the Windows 10 operating system independently tries to fit drivers for all connected devices, the user has the opportunity to see in the device manager which network card is installed in the computer. After that, download the drivers from the official websites of the manufacturer of the motherboard or the network card itself.

1. Press the Win+X key combination, and in the context menu that opens, select Device Manager.
2. In the window that opens, expand the Network adapters list and look for which adapter you need to update the drivers for.

In addition to the network adapter drivers, we also recommend installing the latest drivers for all devices on the computer. It’s not even easy to install, but to perform a clean installation of drivers. A clean installation of drivers means that you must remove old drivers before installation.

Recovering system files

Next, we recommend checking and restoring the integrity of Windows 10 system files. Since problems in the operating system often appear precisely because of a violation of the integrity of system files. There are several options for checking and restoring system files, which you can find out at the link above. The user only needs to run one command in a running Command Prompt as an administrator in Windows 10.

1. Search for Command Prompt and click Run as administrator.
2. In the window that opens, run the command sfc /scannow
   and wait for the recovery to complete.

Disabling Fast Startup

After a clean installation of the operating system, Fast Startup is enabled by default. In some situations, users can benefit from completely disabling Windows 10 Fast Launch. The user just needs to disable Fast Launch for a while and check the computer's performance. For more details, see the instructions: How to enable Windows 10 fast startup.

1. Open the control panel by executing the Control panel command in the Win+R window.
2. Go to Hardware and Sound > Power Options > What the Power Buttons Do.
3. In your current location, click Change settings that are currently unavailable and uncheck Turn on Fast Startup (recommended).

To completely disable fast startup of the operating system, although it is recommended, save the changes and restart the computer. We also recommend resetting the motherboard’s Bios settings to standard, even if you haven’t made any changes to them yourself.

Conclusion

A critical error with event code 41 Kernel-Power is familiar to many users of the Windows 10 operating system. Since in the event log after the computer completely freezes during operation, the user discovers event 41 Kernel-Power. The problem is that the Kernel-Power error is critical and leads to the computer shutting down with errors.

Resolving conflict between 2 sound cards

If two sound cards are installed, they can interfere with each other's operation and cause critical errors. However, there is a way to resolve the conflict.

1. In the Run line, type devmgmt.msc and press Enter.
2. Expand the "Sound, Game and Video Devices" section.
3. Find duplicate equipment in the list and disable it (Right click on the device name, then “Disable”).

4. Reboot.

Disabling devices connected to the second audio card should significantly increase the stability of the operating system and eliminate crashes.

Causes of the problem

Among the most likely causes of the failure we are examining are the following:

1. The presence of outdated versions of drivers that are not able to interact with Windows The problem is especially relevant for older devices.
2. Damage to system files. Damage, which can occur for various reasons, leads to the fact that part of the functionality begins to work with errors. Most often, problems are caused by the quick startup function, which is aimed at speeding up the system startup process - turning it off sometimes helps fix problems.
3. Equipment incompatibility or malfunction. An irresponsible approach to the selection of components can lead to the fact that some components are simply incompatible with each other. This is especially true for RAM - it may not work correctly if you simultaneously use several sticks from different manufacturers.
4. Illiterate overclocking of the processor, RAM or other components. The overclocking procedure must be treated as responsibly as possible - after incorrect actions and uncontrolled overestimations, components can become unstable.

Kernel power 41 - causes of error

Like almost any critical error, “Kernel-power event code 41 task category 63” is accompanied by an uncontrolled reboot of the operating system, and sometimes the appearance of a blue screen with notification of the error code and the problematic file/component.

In the logs of this error you can find a description that looks like this: “The system rebooted without completely shutting down. This error could be the result of the system becoming unresponsive, experiencing a critical failure, or unexpectedly losing power." However, such a description gives absolutely no clue about the reasons for the system failure.

And there are a great many possible reasons, and in 99% of cases the problem is purely hardware in nature and is mainly associated with incorrect operation:

• Power supply;
• Random access memory;
• Controllers;
• Processor;
• Motherboard.

The main sources of the problem under consideration are the first two points, based on which you should look for a solution to the problem.

As an alternative way to solve the problem, it is worth trying to cause a blue screen (if one did not appear when the error occurred).

To do this, open “My/This Computer”, then right-click on an empty space in the window, call up “Properties” and go to the “Advanced system settings” section.

In the window that opens, go to the “Advanced” tab and click on the “Options” button in the “Boot and Recovery” block.

Here you need to pay attention to:

• the need to uncheck the “Perform automatic reboot” line;
• “Dump file”, which has a save path of “%SystemRoot%\MEMORY.DMP”.

This file is created automatically and contains the above-mentioned logs with a description and explanation of the error.

What to do if a critical error occurs - option 1

It should be immediately noted that the error with “kernel-power”, due to the specificity of its cause-and-effect relationship, extremely rarely occurs on laptops, therefore all options and methods for solving the problem are applicable specifically to prefabricated/stationary personal computers.

Also, this error indicates that there are problems with the power supply of any component, which causes a critical system failure, but you should not accurately identify the problematic component based only on software readings (which may show incorrect diagnostic results) - it is better to check the power supply “ “the old fashioned way” using a multimeter or contact a service center for a more in-depth diagnosis of your computer by specialists.

So, if you have a multimeter, do the following:

• Remove the power supply from the case;
• Connect a component (for example, a cooling cooler) to the power supply to create a load - this is necessary to obtain the most reliable results from its operation.
• Using a jumper, close two contacts - “PS-ON” and “COM” (i.e. 0), on many power supplies they are marked green and black, respectively, and are located next to each other. If your power supply does not have color separation, then rely on the standard pinout diagram.

• After connecting the load source and installing the jumper, turn on the power supply to the mains, after which two coolers should start working - the 1st connected for the load, the 2nd cooling the power supply itself.
• The pinout diagram also shows the indicators that the contacts should produce (for example, yellow contacts should have + 12V, red + 5V, and orange + 3.3V).

Using these requirements as a basis, test the voltage at each of the 20 or 24 wires.

Any results obtained that deviate from the norm may indicate that the cause of the critical error is related to unstable operation of the power supply.

Solving the problem - option 2

The second most common cause of the “kernel-power” error is faulty or incompatible RAM installed.

As the minds have already said, any testing - even with various software tools - can provide results about the absence of errors and malfunctions, but in fact there are such.

Therefore, without wasting too much time, try gradually disconnecting the installed RAM memory sticks - in order to find out whether the problem is really related to them, or whether you should “dig” in a different direction.

Also pay attention to the compatibility of the RAM and motherboard.

Change your power settings

The best way to fix the Kernel-Power problem is by changing your power settings. Since it is possible to change the way Windows supplies power to each of the devices, this is one way to get rid of the problem. Below we will show you the changes you need to make to prevent your system from crashing in the manner mentioned earlier.

1. Type Power and sleep options in the search bar next to the Start Menu .
2. Open them and go to Advanced power options .
3. Find the plan you selected and click Set up power plan .
4. Now click Change advanced power settings .
5. Find Hard Drive . Click on it and then select Turn off hard drive via .
6. Change both the On Battery and Plugged in options to Never and save the changes by clicking Apply .
7. Finally, you should repeat the previous step, only with Sleep After . You can find it by expanding the Sleep from the list.
