Critical Structure Corruption Windows 8.1


I recently tried to install a virtual drive and image creation program called alcohol 120% onto my Windows 8.1 and the installation stalled and was interrupted. After this, the system began restarting randomly giving me a Critical Structure Corruption message. 

Here is my minidump file from after the crash:

The attached DMP file is 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.

We unfortunately get very little to no information whatsoever for *109 dumps, so we'll need to do some detective work:

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

sptd.sys is listed and loaded in your modules list - SCSI Pass Through Direct Host - Daemon Tools + Alcohol 120 (known BSOD issues with Win7 and especially 8). Uninstall this software and then sptd.sys with the uninstaller afterwards ASAP -
