The “IRQL_GT_ZERO_AT_SYSTEM_SERVICE” Blue Screen of Death error (0x0000004A) typically happens when a system service running at an IRQL greater than PASSIVE_LEVEL is returning back to normal user mode from a system call. It’s a fatal error that may be caused by a range of factors, including system files corruption, outdated or incompatible drivers, and system bugs.

How to fix:

  1. Update Your System Drivers: Outdated or incompatible drivers could cause this error. Ensure all of your system drivers are up-to-date. This can be done through the Device Manager in Windows or by visiting the manufacturer’s website and downloading the latest drivers.
  2. Windows Update: Make sure that your system is up-to-date. Microsoft periodically releases updates and patches that can fix issues that cause this error.
  3. Run System File Check (SFC): SFC is a Windows utility that allows users to scan for corruptions in system files and restore them. To run it, open Command Prompt as an administrator, type sfc /scannow, and then press Enter.
  4. Check for Malware: Sometimes, malware or viruses can cause system errors. Run a full system scan using your preferred antivirus software to ensure your system is clean.
  5. Use System Restore: If the error started appearing recently, you might want to use System Restore to revert your system back to a point when it was working correctly.

Always remember to back up your important data before performing any of these steps. If the issue persists, you might want to consider reaching out to a professional for help.
