Solutions for ntdll.dll Crashes on Windows 10
"ntdll.dll" is a critical Dynamic Link Library (DLL) in the Windows operating system, responsible for handling system calls and low-level operations.
When ntdll.dll crashes, it can lead to application freezes, Blue Screen of Death (BSOD), or system instability. This guide provides effective solutions to resolve ntdll.dll crashes on Windows 10.
1. Update Drivers
Outdated or corrupted drivers can cause system compatibility issues, leading to ntdll.dll crashes. Regularly updating your drivers is essential for system stability. Using Driver Sentry can help automatically detect and update drivers, preventing the risk of downloading or installing incorrect drivers.
Download the latest version of Driver Sentry by clicking the download button and install the software. Open Driver Sentry and click "Scan" to detect outdated or missing drivers.

In the command prompt, enter the following commands and press Enter after each:

Restart your computer and check if the issue is resolved.
3. Run System File Checker (SFC) and DISM
Steps to Run SFC:
Open Command Prompt as Administrator.
Type the following command and press Enter: sfc /scannow
Wait for the scan to complete. If the message "Windows Resource Protection found corrupt files and successfully repaired them" appears, restart your computer.
If SFC Fails, Run DISM:
If SFC cannot repair the files, use the Deployment Image Servicing and Management (DISM) tool: DISM /Online /Cleanup-Image /RestoreHealth
This command downloads healthy system files from Windows Update.
Restart your PC after the process completes.
4. Replace the Corrupted ntdll.dll File

On another working Windows 10 PC, copy the ntdll.dll file from the same directory and transfer it to a USB drive.
Rename the corrupted ntdll.dll file to "ntdll_old.dll" as a backup.
Copy the healthy ntdll.dll file to "C:\Windows\System32".
Right-click the new file, select "Properties > Security > Advanced", and ensure the Administrators group has full control.
Restart your PC and check if the problem is resolved.
5. Run the Program Compatibility Troubleshooter

Select "Try recommended settings", and let Windows suggest a fix.

Click "Apply > OK", then restart the application and check for crashes.
6. Check for Hardware Issues

Press Win + R, type "mdsched.exe", and press Enter.
Select "Restart now and check for problems (recommended)".
The system will restart and scan your RAM for errors.
If issues are found, consider replacing the faulty RAM.
Run CHKDSK to Check Hard Drive:
Open Command Prompt as Administrator.
Type the following command and press Enter: chkdsk C: /f /r
(Replace C: with the appropriate drive letter if necessary.)
If prompted to schedule a disk check at the next restart, type Y and press Enter.
