If you encounter issues with npsvctrig.sys leading to blue screens (often labeled as “BSOD” for Blue Screen of Death), it could indicate hardware conflicts, driver incompatibility, or corruption within the file itself.
To address potential issues and reinstall this system file:
- Ensure your computer is connected to a stable internet connection.
- Press Win+X, then select ‘Command Prompt (Admin)’ from the menu.
- In Command Prompt, type `sfc /scannow` and hit Enter. This command scans your system for corrupted files and replaces them with a cached copy of the original file if available.
- After SFC scan completes, restart your computer to apply any changes made by the utility.
- If the issue persists after SFC repair, run DISM (Deployment Image Servicing and Management) tool. Open Command Prompt again as an administrator, type `DISM /Online /Cleanup-Image /ScanHealth` followed by pressing Enter.
