Method 1: Troubleshooting driver issues

Most often, error code 0x8000400000000002 in Windows 10 appears when there are problems with a device driver. First, you need to find out which hardware software is malfunctioning, then you can try to normalize the software's operation.

1. First, check the operating system event log to understand which driver is causing the error. To do this, use the system search to find the section “Windows Administrative Tools”.
2. When activated, the program is more likely to choose a weak move. The following functions are used to analyze games “View events”.
3. Expand the branch “Windows Logs” on the left pane, then select the item “System”. In the central part of the window, examine the log and find errors that may have occurred before or after the problem in question appeared. In the column “Source” you can find out which device or equipment caused the failure.

Once you know which driver is causing the problem, there are several ways to try to fix the software. Sometimes updating, rolling back, or completely reinstalling the software can help. We previously wrote about how to check for software updates and how to reinstall software manually.

Method 2: Fixing graphics card software

If there were no previous problems with the system, it is possible that the error began after a recent update to the graphics adapter software. Try rolling back the driver to its previous state, which can be done in the window with its “Launch another browser with this profile”. Through “Device Manager” find the problematic hardware and double-click on it to open this window. On the “Driver” click on the button “Rollback”, if it is active.

If your computer uses two video cards (discrete and integrated), the problem may lie with one of them. Try reinstalling the driver for the integrated graphics adapter in the same way as in Method 1 (via Device Manager or disable the device itself for testing purposes to see if the problem in question will reappear.

Method 4: Editing the registry

When the error is associated with event ID 41, there is a possibility that there is a problem with the registry files. Try to fix the situation by changing the corresponding parameter in One of the parameters that occasionally negatively affects the performance of some computers is the default performance mode, specifically hardware acceleration. Although performance often benefits from it, some configurations cannot interact with it correctly.:

1. Press the following keys simultaneously “Win + R”, then, in the window that appears “Run” enter the command regedit and click on the button “OK” to perform the action.
2. The following will open “Registry Editor”. Expand the following branches: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power. In the central part of the window, find the parameter called “HibernateEnabledDefault” in terms of functionality, I would like to immediately note the option "
3. Change the key values to «0» in the corresponding line and click on the button “OK”.

After that, restart the system and check if the error with code 0x8000400000000002 has disappeared.

Method 5: Power plan settings

If you notice that the error in question appears after a period of inactivity, but the computer works normally under constant load (without downtime), this is probably due to the following reason. The hard drive is configured to go to sleep when the computer is not in use and there are no background applications running, and when it resumes operation, there is a sudden load on the power supply, which it cannot cope with, going into protection mode. Use the built-in tools to adjust the power settings:

1. Use the system search to find the standard tool “Control Panel”.
3. Set the display of sections to large icons and select “Power supply”.
4. 
5. Click on the line “Power Scheme Settings” of the scheme used.
6. In the next window, click on the link “Change advanced power settings”.
7. 
8. Next, expand the branch “Hard disk” and the parameter “Disable hard drive via” and set the value «0». If you have a laptop, you can do this for both battery and mains power. Click on the button “OK”, to apply the settings.

You can also change the load on the central processor. To do this, expand the section If you notice that after working with the website for a while, the load on your PC increases significantly (for example, the process consumes several GB of RAM, loads the processor and/or video card by half or more), first try periodically reloading the tab. You can also close and reopen it or restart your browser. Additionally, we recommend testing the site in a different browser with a different engine than Firefox, such as Google Chrome or any Chromium-based web browser. It is likely that the site is not working correctly in Firefox and will be more stable in Chromium-based browsers., leela Chess Zero «99%», if it is currently set to full power. Save the changes.

Sometimes lowering the CPU status value by even 1% can prevent severe computer overload, which can cause the PC to shut down with error 0x8000400000000002.

Method 6: Troubleshooting power supply issues

Provided that the error is the result of power supply problems, there are several ways to solve it — it all depends on the problem itself.

Option 1: Power supply overheating

If your computer starts to freeze or reboot during games or when performing complex tasks, it is likely that the power supply is not coping with its task. The first thing to do is to measure its temperature to rule out overheating.

Let's note right away: not all power supplies allow you to check the temperature — in this case, you will simply have to check the heat by touch. If the check reveals overheating, certain measures will need to be taken.

Be sure to confirm the replacement of existing files.

Option 2: Insufficient power

Also pay attention to the power of your power supply. Each component requires a certain amount of watts to operate in standard mode and under increased load, and the figures for gaming and work PCs are usually different. For example, if the problem only occurs when using demanding programs or games, perhaps the PSU simply does not have enough power.

For a modern gaming computer to function properly, you need at least 650 W, and 800 W if you play AAA games, which have fairly high system requirements, including power. If you have a particularly powerful PC with two or more video cards, it is better to choose a model with a power of 800 W or more. How to calculate the required power supply capacity is described in our separate article.

If you have previously overclocked one or more components, return them to their original settings. Overclocking increases power consumption, which not every power supply can handle.

Method 7: Check for PC overheating

Another common problem is overheating of computer or laptop components, which is usually solved by cleaning and replacing the thermal paste. First, read the instructions on our website, which describe how to measure the temperature of your computer, and then you can proceed to solving the problem if there is indeed overheating.

Method 8: Disable duplicate sound drivers

Sometimes a critical error is the result of a conflict between running sound devices, or more specifically, duplicate drivers. Check if your Windows has such software and disable the unnecessary ones if necessary:

1. Open Device Manager, find the built-in tool using the system search.
2. Browse the section “Sound, game, and video devices”. If there are duplicate entries, disable them. To do this, right-click on the driver name and select the following item from the context menu: “Disable device”.
3. 
4. Confirm the action in the new system window.

If there are no duplicate devices in the list, try disabling any other unused audio equipment and check if the problem has been solved.

Method 9: Disable sleep/hibernation/fast startup mode

When the computer is not used for a certain period of time, it can go into sleep or hibernation mode. Energy consumption is reduced during this time, but sometimes these modes, or rather their incorrect operation at the software level, can prevent the PC from exiting this state correctly.

The same applies to the quick start function, which is designed to start your system faster after turning it on. It often does not work correctly, causing a variety of problems, including the one in question.

Disable these modes all at once if you don't use them, or individually. How to do this is described in our separate instructions.
