大多数情况下，您会在安装新软件或硬件后遇到内核安全检查失败错误。好吧，当您升级 Windows 时，您会收到此错误，因为以前版本的Windows的驱动程序将与新版本不兼容。因此^(Hence)，留下内核安全检查^{(Kernel Security Check)}失败BSOD错误。

内核安全检查失败错误的原因：

• ^(Virus)已损坏Windows 操作系统^{(Windows OS)}文件的病毒或恶意软件感染。
• 设备驱动程序已过时或未正确配置。
• 损坏或坏记忆。
• 硬件或软件冲突。
• 硬盘损坏或损坏。

首先，您需要启用旧版引导，如果您不知道该怎么做，只需按照这篇文章启用您的高级旧版引导选项^{(enable your advanced legacy boot option)}即可。

在尝试以下技术方法之前，建议您执行以下操作以修复内核安全检查失败 ( KERNEL_SECURITY_CHECK_FAILURE ) 错误：

• 如果您购买了另一种防病毒软件，请^(Make)确保只有一种防病毒软件正在运行，请确保关闭 Windows Defender^{( turn off Windows Defender)}。
• 运行自动修复或使用系统还原来尝试修复问题。
• 使用您的防病毒软件运行完整的系统病毒和恶意软件扫描。
• ^(Install)通过Windows更新^(Windows)安装任何挂起的更新。
• 从制造商的网站重新安装驱动程序。
• 运行恶意软件字节。

修复内核^{(Fix kernel)}安全检查失败（KERNEL_SECURITY_CHECK_FAILURE）

方法一：卸载显卡驱动^{(Method 1: Uninstall Graphic Card Driver)}

1. 从高级启动菜单^{(advanced boot menu)}将您的 PC 启动到安全模式。

2. 按Windows Key + R然后键入“ devmgmt.msc ”并按 Enter 进入设备管理器。

3. 在设备管理器^{(Device Manager)}中，展开显示^(Display)适配器。

4.接下来，选择您的Nvidia卡^{( Nvidia card)}，然后右键单击然后选择属性。^{(Properties.)}

5. 现在选择驱动程序选项卡^{(Drivers tab)}并单击回滚驱动程序^{(Roll Back Driver)}（如果要求确认，请单击是^(Yes)确认）。

6. 如果回滚^{(Roll Back)}选项显示为灰色，则单击“卸载^(Uninstall)”卸载该驱动程序。

7.重新启动您的PC并在高级启动中选择“正常启动您的PC”。^{( “Start your PC normally.”)}

方法 2：运行驱动程序验证程序^{(Method 2: Run Driver Verifier)}

此方法仅在您可以正常登录 Windows 时有用，而不是在安全模式下。接下来，确保创建一个系统还原点。

要运行驱动程序验证程序^{(Driver Verifier)}以修复内核安全检查失败，请转到此处。^{(go here.)}

方法 3：运行系统文件检查器并检查磁盘^{(Method 3: Run System File Checker and Check Disk)}

1.再次^(Again)，从上述高级启动菜单将您的 PC 启动到安全模式。^(Boot)

2. 登录到安全模式后，按Windows键 + X 并单击命令提示符（管理员）。^{(Command Prompt(Admin).)}

3. 在命令提示符下，键入以下命令并在每个命令后按回车键：

sfc /scannow
chkdsk /f C:

4. 进程完成后，退出 cmd。

5. 现在在Windows搜索栏中输入内存并选择“ Windows 内存诊断”。^{(Windows Memory Diagnostic.)}”

6. 在显示的选项集中，选择“立即重启并检查问题^{(Restart now and check for problems)}”。

7. 之后，Windows将重新启动以检查可能的 RAM 错误，并希望显示您收到^(Windows)蓝屏死机 (BSOD)^{(Blue Screen of Death (BSOD))}错误消息的可能原因。

8. 重新启动您的 PC 并检查问题是否已解决。

方法四：运行 Memtest86^{(Method 4: Run Memtest86)}

可以肯定的是，再次运行内存测试，但这次使用Memtest，因为它消除了所有可能的异常，并且它比内置内存测试更好，因为它在Windows环境之外运行。

注意：在开始之前，请确保您可以访问另一台计算机，因为您需要将软件下载并刻录到光盘或USB闪存驱动器。运行Memtest^(Memtest)时最好让计算机过夜，因为这肯定需要一些时间。

1. 将USB 闪存驱动器^{(USB flash drive)}连接到您的工作 PC。

2. 下载并安装适用于 USB Key 的 Windows Memtest86 自动安装程序^{(Windows Memtest86 Auto-installer for USB Key)}。

3. 右键单击​​下载的图像文件^{(downloaded image file)}，然后选择“在此处提取^{(Extract here)}”选项。

4. 解压后，打开文件夹^(folder)并运行Memtest86+ USB Installer。

5. 选择您插入的 USB 驱动器^{(plugged USB drive)}来刻录MemTest86软件（这将擦除USB中的所有内容）。

6. 上述过程完成后，将USB插入PC，出现KERNEL_SECURITY_CHECK_FAILURE 错误^{( KERNEL_SECURITY_CHECK_FAILURE error)}。

7. 重新启动您的 PC 并确保选择从USB闪存驱动器启动。

8. Memtest86将开始测试您系统中的内存损坏。

9. 如果你通过了所有 8 个阶段的测试，你可以确定你的记忆工作正常。

10. 如果某些步骤不成功，那么Memtest86会发现内存损坏，这意味着您的内核安全检查失败^{( kernel security check failure)}( KERNEL_SECURITY_CHECK_FAILURE ) 蓝屏死机错误是因为内存损坏/损坏。

11.为了修复内核安全检查失败错误^{(fix kernel security check failure error)}，如果发现坏内存扇区，您将需要更换您的RAM 。

方法 5：运行磁盘清理和错误检查^{(Method 5: Run Disk Cleanup and Error Checking)}

1.再次^(Again)，将您的 Windows 引导至安全模式，并针对您拥有的每个硬盘分区执行以下步骤（例如驱动器 C^{(Drive C)} : 或 E:)。

2. 转到这台电脑或我的电脑^{(PC or My PC)}，然后右键单击驱动器^(drive)以选择属性。^{(Properties.)}

3. 现在，从“属性^(Properties)”窗口中，选择“磁盘清理^{(Disk Cleanup)}”并单击“清理系统文件”。^{( system files.)}

4. 再次，转到属性窗口^{(properties windows)}并选择工具选项卡^{(Tools tab)}。

5. 接下来，单击错误检查^(Check)下的检查。^{(Error-checking.)}

6. 按照屏幕提示完成错误检查。

7.重新启动您的PC并正常启动到Windows。

就是这样，您已成功 修复内核安全检查失败（KERNEL_SECURITY_CHECK_FAILURE），^{(Fix kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE), )}但如果您对本指南仍有任何疑问，请随时在评论部分询问。

Fix kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE)

Most of the tіme, you will expеrіence a kernel security check failure error after yоu have installed new software or hardware. Well, you will get thiѕ errоr when you will upgrade your windows bеcause the driνers of previous versions of Windows will not be compatible with the new one. Hence, leaving with you the Kernel Sеcurity Check failure BSOD error.

Causes of kernel security check failure errors:

• Virus or malware infection that has corrupted Windows OS files.
• Device drivers are outdated or not properly configured.
• Corrupted or bad memory.
• Conflicting hardware or software.
• Damaged or corrupted Hard Disk.

First, your need to enable legacy boot, and if you don’t know how to do that, just follow this post to enable your advanced legacy boot option.

Before trying the below technical methods it’s advised that you do the following in order to fix kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE) error:

• Make sure only one antivirus is running if you have purchased another make sure to turn off Windows Defender.
• Run Automatic Repair or use System Restore to try to fix the issue.
• Run a full system virus and malware scan with your antivirus.
• Install any pending updates through Windows update.
• Reinstall drivers from the manufacturer’s website.
• Run malware bytes.

Fix kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE)

Method 1: Uninstall Graphic Card Driver

1. Boot your PC into Safe mode from the advanced boot menu.

2. Press Windows Key + R then type “devmgmt.msc” and hit Enter to Device Manager.

3. In Device Manager, expand the Display adapter.

4. Next, select your Nvidia card and then right click then select Properties.

5. Now select the Drivers tab and click on Roll Back Driver (If asked for confirmation click Yes to confirm).

6. If the Roll Back option is grayed out then click “Uninstall” to uninstall this driver.

7. Restart your PC and on the advanced boot, select “Start your PC normally.”

Method 2: Run Driver Verifier

This method is only useful if you can normally log into your Windows, not in the safe mode. Next, make sure to create a System Restore point.

To run Driver Verifier to fix kernel security check failure, go here.

Method 3: Run System File Checker and Check Disk

1. Again, Boot your PC into safe mode from the above-advanced boot menu.

2. Once you login into safe mode, press Windows key + X and click on Command Prompt(Admin).

3. In the command prompt, type the following command and hit enter after each one:

sfc /scannow
chkdsk /f C:

4. Once the process is finished, exit the cmd.

5. Now type memory in the Windows search bar and select “Windows Memory Diagnostic.”

6. In the set of options displayed, select “Restart now and check for problems.”

7. After which Windows will restart to check for possible RAM errors and will hopefully display the possible reasons as for why you get the Blue Screen of Death (BSOD) error message.

8. Reboot your PC and check if the problem is resolved or not.

Method 4: Run Memtest86

To be sure, again run the memory test, but this time using Memtest as it eliminates all the possible exceptions, and it’s better than the built-in memory test as it runs outside the Windows environment.

Note: Before starting, make sure you have access to another computer as you will need to download and burn the software to the disc or USB flash drive. It’s best to leave the computer overnight when running Memtest as it sure likely to takes some time.

1. Connect a USB flash drive to your working PC.

2. Download and install Windows Memtest86 Auto-installer for USB Key.

3. Right-click on the downloaded image file and select the “Extract here” option.

4. Once extracted, open the folder and run the Memtest86+ USB Installer.

5. Choose your plugged USB drive to burn the MemTest86 software (This will erase all the content from your USB).

6. Once the above process is finished, insert the USB to the PC, giving the KERNEL_SECURITY_CHECK_FAILURE error.

7. Restart your PC and make sure boot from USB flash drive is selected.

8. Memtest86 will begin testing for memory corruption in your system.

9. If you have passed all 8 phases of the test, you can be sure that your memory is working correctly.

10. If some of the steps were unsuccessful, then Memtest86 will find memory corruption which means that your kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE) blue screen of death error is because of bad/corrupt memory.

11.In order to fix kernel security check failure error, you will need to replace your RAM if bad memory sectors are found.

Method 5: Run Disk Cleanup and Error Checking

1. Again, boot your windows into safe mode and follow the below steps for each hard disk partition you have(example Drive C: or E:).

2. Go to This PC or My PC and right-click on the drive to select Properties.

3. Now, from the Properties window, select Disk Cleanup and click clean up system files.

4. Again, go to the properties windows and select the Tools tab.

5. Next, click on Check under Error-checking.

6. Follow the on-screen instruction to finish error checking.

7. Restart your PC and boot to windows normally.

That’s it, you have successfully Fix kernel security check failure (KERNEL_SECURITY_CHECK_FAILURE), but if you still have any queries regarding this guide, then feel free to ask them in the comments section.
