How to fix error code 0x00000001 on Windows 10

Windows Boot Manager error code 0xc0000001 is one of the common Blue Screen of Death (BSoD) error codes that prevent the operating system from booting normally.

Reasons for the error include the installation of problematic software, corruption of system files or PC memory. The error can also be caused by damage to the SAM (Security Account Manager) file.

0xc0000001 Windows 10 on boot

Why does this error appear?

Error code 0xc0000001 often indicates problems with the computer's boot device or that some boot files are corrupt. The error may also appear if there are problems with the PC boot sector.

The error appears as a result:

Corruption or corruption of the SAM (system credential store) file. This file is important for Windows to start, and if the file is deleted or corrupted, the boot process will stop.
Damage to OS system files. The error may appear if key system boot-related files become damaged due to disk writing problems, power outages, or virus attacks.
File system integrity violations. Sometimes the file system is severely damaged as a result of a virus attack, poor PC power, etc.
RAM damage. The error can be a result of various problems with the PC's random access memory (RAM).

Reason for error 0x01

Any version of the operating system is subject to problems, including the stop error 0x00000001. The reasons for its occurrence almost always lie in the unstable operation of the system, which is caused by a specific driver. However, there are also indirect factors that can cause BSoD with the described problem.

On Windows 10

The main reason for causing a blue screen with error information 0x00000001 in the “ten” is a violation of synchronization between procedure calls, caused by a specific driver. In addition to the incorrect sequence of requests, an incorrect driver can also call procedures multiple times, which also does not contribute to the normal operation of the computer.

Quite often the problem occurs when connecting new devices. For example, when replacing a video card with a more modern one, the graphics driver, which still intends to operate with the old device, will conflict with the new video card.

Similar problems can be caused by any driver that does not support the updated device. Among the conflicting drivers, BSoD can cause the following:

tcpip.sys;
ntoskrnl.exe;
ndis.sys;
raspppoe.sys;
win32k.sys;
psi.sys.

It is advisable to check them first.

In addition to the main cause of a blue screen associated with a driver conflict, there are some indirect factors that can also lead to error 0x00000001.

Incorrect operation of RAM.
Change in RAM speed.
The presence of bad sectors of the hard drive.
Connecting an external hard drive.
Dead motherboard battery.
Problems with any system device.
PC infection with viruses.
Damage to system files.

Sometimes, when this problem occurs, users immediately begin to look for the cause in the incorrect operation of the drivers and are perplexed if the standard procedure for updating control files does not save the situation. All possible causes of BSoD should be considered. They can even consist of a full hard drive and contamination of the computer hardware.

On Windows 7

For Windows 7, error 0x00000001 usually occurs for the same reasons. Replacing outdated hardware results in a conflict with the wrong driver version. However, given that this version of the operating system is still several steps lower than the same “top ten”, some devices require more advanced capabilities and are unable to work correctly.

If the error appears immediately after installing Windows 7, when the computer, at first glance, is completely clean, and there can be no reason for a blue screen, you should check the installation device. If it is a disk and it is damaged, the OS may not install correctly. A portable hard drive can also conflict with the “seven”. Another important reason for BSoD in Windows 7 may be the use of a USB 3.0 connector (you can distinguish it from 2.0 by its blue color). "Seven" does not have standard drivers for this port, so problems may arise when using it.

When diagnosing a system failure 0x00000001 for both the “ten” and “seven”, it is necessary to take into account indirect factors that can cause the “screen of death”. It is worth checking the serviceability of the RAM blades, the integrity of the hard drive, the absence of malware and other possible problems.

Solution to stop error 0x00000001

Having an idea of why a “blue screen of death” with a description of stop error 0x00000001 may appear when operating Windows 7 and 10 operating systems, you can solve the problem yourself. First of all, you need to check the correctness of the drivers and the relevance of their updates, but you should not forget about possible other reasons.

Resolving apc index mismatch in Windows 10

When the computer hardware is replaced, after which a blue screen begins to appear, the corresponding drivers should be updated. If this procedure does not resolve the problem, it is likely hidden in some other control file. You can try to download the update yourself from the manufacturer’s website or use a special utility. For example, using the DriverDoc program, you can ensure automatic driver updates, which will make the process much easier.

Error 0x0000001a in Windows 10 is associated with incorrect operation of the Windows Operating System program. It must be uninstalled using the control panel and installed again. Perhaps after this the PC will work normally. It would be a good idea to check the operating system for viruses. If they are found, it is imperative to get rid of them. Sometimes using even reputable antivirus software is not enough. To clean your PC from malicious files, you should use Emsisoft Anti-Malware.

If viruses are detected, the computer is cleaned, and the problem still remains, then it is likely that malware has damaged system files and the blue screen problem is related to this. You need to check your computer for broken files. You can do this thanks to sfc/scannow.

Since BSoD is often associated with a broken RAM device, you need to check its operation. The OP ruler should be removed and cleaned of dust and dirt. There may be a problem with the device's contacts. If several dies are installed in the PC at once, you need to remove them one by one to determine which of them has become unusable. It is possible that the amount of memory present on this device is not enough for normal operation of the computer. Sometimes replacing the RAM or adding additional capacity solves the blue screen issue.

You should check the health of the hard drive. The presence of bad sectors quite often leads to incorrect operation of the PC. If a blue screen occurs when a portable hard drive or other similar device is connected to the computer, then it is worth checking whether the error disappears after disconnecting the external equipment.

Sometimes flashing the BIOS is necessary to eliminate the “screen of death”. However, not every user is ready for such an operation, so it is better to contact a specialist to carry it out.

A complete reinstallation of Windows will eliminate software causes of BSoD, and if after this the error still appears on the screen, then the problem is definitely in the hardware. You need to check the serviceability of your computer components. Some of them may need to be replaced.

Resolving apc index mismatch in Windows 7

In the Windows 7 and 10 operating systems, the algorithms for fixing the error are very similar. You should start with driver updates. The specificity of the "seven" is that the updated driver may conflict with the operating system kernel. To prevent this from happening, you should update Windows. Then the problem can be successfully resolved.

If suddenly the cause of the blue screen is different, you need to perform the same manipulations as for the “ten”: clean your PC of viruses, find and restore damaged files, check the equipment for serviceability, and so on. As a last resort, you can reinstall the operating system yourself or use the services of a computer technician.
