Q: Windows 8.1 has found Critical Structure Corruption

Performed a Windows Update yesterday and I have been getting this BSOD evey 25 minutes., It has ruined my brand new computer!!

Below are the installed updates;

Bluetooth 4.0 Module
Generic IO & Memory Access
Flash Player for Windows 8.1 for x64 KB2916626


Thank you




All of the attached DMP files are of the CRITICAL_STRUCTURE_CORRUPTION (109) bug check.

This indicates that the kernel has detected critical kernel code or data corruption.

There are generally two causes for this bug check:
  1. A driver has inadvertently, or deliberately, modified critical kernel code or data. Microsoft Windows Server 2003 with Service Pack 1 (SP1) and later versions of Windows for x64-based computers do not allow the kernel to be patched except through authorized Microsoft-originated hot patches. For more information, see Patching Policy for x64-based Systems.
  2. A hardware corruption occurred. For example, the kernel code or data could have been stored in memory that failed.


1. Remove and replace ESET with Windows 8's built-in Windows Defender for temporary troubleshooting purposes:

ESET removal -

Windows Defender (how to turn on after removal) -

2. sptd.sys is listed and loaded in your modules list; SCSI Pass Through Direct Host - Daemon Tools (known BSOD issues with Win 7 and 8). Please remove it ASAP with the uninstaller tool -

Did this solve your problem?
