The “ASSIGN DRIVE LETTERS FAILED” BSOD (Blue Screen of Death) error appears on the screen during the initialization process for Windows and is caused by the failure of the system to assign a drive letter. The process of assigning the drive letter is implemented in Windows to identify partitions and logical disk drives in the root file system. This BSOD error is usually associated with a faulty device driver for a recently installed device. This BSOD error is also known as “ASSIGN_DRIVE_LETTERS_FAILED” and “Windows STOP 0x00000072“. It displays an error […]

The “APC INDEX MISMATCH” BSOD (Blue Screen of Death) error appears on the screen during the initialization process for Windows when there is a mismatched thread between the APC (Asynchronous Procedure Calls) index and a device driver that operates in the kernel mode of the system. It is triggered by events that include the improper shutdown of the computer, incomplete installation or uninstallation of a program, recovery from a virus attack, and corruption of the system memory that results in the deletion of entries in the Windows system files. The […]

The “APP TAGGING INITIALIZATION FAILED” BSOD (Blue Screen of Death) error appears on the screen during the initialization process for Windows and is most likely caused by corrupted or missing device driver or a faulty device that has been recently installed. It means that initialization of an application has failed while being loaded by the operating system. This error usually appears when a device driver is corrupted, is incorrectly installed, or is not updated. This BSOD error is also known as “APP_TAGGING_INITIALIZATION_FAILED” and “Windows STOP 0x0000010A“. It displays an error […]

The “ATDISK DRIVER INTERNAL” BSOD (Blue Screen of Death) error appears during the startup process for the operating system and when the system has been operational due to a faulty device driver. The error automatically shuts down the system due to an internal error or bug in a device driver that is installed on the hard disk of the computer. Other factors that can cause this BSOD error are faulty hardware and incompatibilities with the Basic Input / Output System (BIOS) settings. This BSOD error is also known as “ATDISK_DRIVER_INTERNAL” […]

The “ATTEMPTED EXECUTE OF NOEXECUTE MEMORY” BSOD (Blue Screen of Death) error appears during the initialization of the operating system when a device driver attempts to execute a program from a non-executable area of the memory. The operating system has pre-defined areas in the memory for storing data, which is the non-executable portion, and the executable area where programs are allowed to run. In this BSOD error, a faulty driver has attempted to run a program from the non-executable section of the memory, which resulted to system shutdown to maintain […]

The “ATTEMPTED SWITCH FROM DPC” BSOD (Blue Screen of Death) error may appear during the initialization process of Windows due to an illegal operation by the DPC (Deferred Procedure Call) routine. The DPC is responsible for completing current IRPs (I/O Request Packets) and ensures that the I/O operation of the device that is next in line is started promptly. The illegal operation that cause this BSOD error can be a wait operation or an attach process that was attempted from a DPC routine. This means that a software or hardware […]
