Repair Windows Error 0x00000109    |    CRITICAL_STRUCTURE_CORRUPTION    |    Fix Error Code 0x00000109


STOP Errors are usually the result of a hardware malfunction or device driver issue. It is also possible to receive a Blue Screen Error due to bad system memory, malfunctioning power supply, components overheating, or hardware overclocked beyond its specification. In older versions of the Windows OS you may also receive Blue Screen Errors due to incompatible DLL files.

Since the only option when receiving a Blue Screen Error is to reboot, any unsaved data is lost. With that in mind, it is very important to eliminate these errors to protect your data.

4The type of the corrupted region. (See the following table later on this page.)

The value of Parameter 4 indicates the type of corrupted region.

Parameter 4Type of Corrupted Region, Type of Corruption, or Type of Action Taken That Caused the Corruption
0x0A generic data region
0x1A function modification or the Itanium-based function location
0x2A processor interrupt dispatch table (IDT)
0x3A processor global descriptor table (GDT)
0x4A type-1 process list corruption
0x5A type-2 process list corruption
0x6A debug routine modification
0x7A critical MSR modification


There are generally three different causes for this stop error code:

  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 Aa469190.internet_link_sm(en-us,MSDN.10).gifPatching Policy for x64-based Systems.
  2. A developer attempted to set a normal kernel breakpoint using a kernel debugger that was not attached when the system was started. Normal breakpoints (bp) can only be set if the debugger is attached at start time. Processor breakpoints (ba) can be set at any time.
  3. A hardware corruption occurred. For example, the kernel code or data could have been stored in memory that failed.
