Hi,
When did this issue start to occur?
Did it happen after installing the KB 5004945?
The KERNEL_SECURITY_CHECK_FAILURE bug check has a value of 0x00000139. This bug check indicates that the kernel has detected the corruption of a critical data structure.
Determining the cause of this issues typically requires the use of the debugger to gather additional information.
These general troubleshooting tips may be helpful.
-If you recently added hardware to the system, try removing or replacing it. Or check with the manufacturer to see if any patches are available.
-If new device drivers or system services have been added recently, try removing or updating them. Try to determine what changed in the system that caused the new bug check code to appear.
-Check the System Log in Event Viewer for additional error messages that might help pinpoint the device or driver that is causing the error. For more information, see Open Event Viewer. Look for critical errors in the system log that occurred in the same time window as the blue screen.
-Look in Device Manager to see if any devices are marked with the exclamation point (!). Review the events log displayed in driver properties for any faulting driver. Try updating the related driver.
-Run a virus detection program. Viruses can infect all types of hard disks formatted for Windows, and resulting disk corruption can generate system bug check codes. Make sure the virus detection program checks the Master Boot Record for infections.
