There is not much information on the net and everything Microsoft says on this blue screen is :

The IRQL_GT_ZERO_AT_SYSTEM_SYSTEM_SERVICE error check has the value 0x0000004A. This indicates that a thread returns to user mode from a system call if its IRQL is still above PASSIVE_LEVEL.


If you get this error, here are some ideas I can offer you :

1] Run Windows 10 Blue Screen Troubleshooting.

2] Make sure you are using the latest version of all installed software and make sure your Windows 10 is updated.

3] Make sure all drives on your device are updated.

4] Check your system BIOS carefully. Is an update available from the system or motherboard manufacturer? If so, update the BIOS. Check BIOS documentation carefully; resetting all BIOS options to their default values can sometimes solve a problem caused by excessive optimization.

5] Run ChkDsk to check your hard disk for errors.

6] Run the Windows and Memtest86+ memory diagnostic tool to check your memory status.

7] There are advanced troubleshooting suggestions for the blue screen that you can consult.

Let’s hope something helps!
