Debugging Tools for Windows


The DRIVER_CORRUPTED_SYSPTES bug check has a value of 0x000000DB. This indicates that an attempt was made to touch memory at an invalid IRQL, probably due to corruption of system PTEs.


The following parameters are displayed on the blue screen.

Parameter Description
1 Memory referenced
3 0: Read

1: Write

4 Address in code which referenced memory


A driver tried to access pageable (or completely invalid) memory at too high of an IRQL. This bug check is almost always caused by drivers that have corrupted system PTEs.

Resolving the Problem

If this bug check occurs, the culprit can be detected by editing the registry. In the \\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management registry key, create or edit the TrackPtes value, and set it equal to DWORD 3. Then reboot. The system will then save stack traces, and if the driver commits the same error, the system will issue bug check 0xDA (SYSTEM_PTE_MISUSE). Then the stack trace will identify the driver that caused the error.
