Update or Reinstall Device Drivers
Update or Reinstall Device Drivers: If the BSOD Stop Code 0xc000021a is caused by device driver issues, you can update or reinstall the drivers to fix the problem. First, navigate to the Device Manager by right-clicking on the Start menu and selecting it from the list. Look for any devices with a yellow exclamation mark next to them, indicating a driver issue. Right-click on the device and select “Update driver” to search for updates online. If that doesn’t work, you can uninstall the driver and then reinstall it by right-clicking on the device and selecting “Uninstall device,” then restarting your computer to automatically reinstall the driver.

Reconfigure Boot and BIOS Settings
1. Restart your computer and access the BIOS settings by pressing a specific key (usually Del, F2, or F10) during startup.

If reconfiguring the BIOS settings does not resolve the issue, you may need to consider other troubleshooting steps such as running CHKDSK, updating device drivers, or scanning for malware with antivirus software.

If the error is resolved after disconnecting the external devices, reconnect them one at a time to identify which device is causing the conflict. Check for any driver updates for the problematic device and install them if available.
Additionally, run a full system scan using Microsoft Defender Antivirus to check for any malware that may be causing the issue. Make sure your Windows operating system is up to date by running Windows Update.
If the issue persists, try booting into Safe Mode to troubleshoot further. In Safe Mode, you can uninstall any recently installed software or drivers that may be causing conflicts. Use the Device Manager to check for any issues with device drivers and update or uninstall them if necessary.
