The “ATTEMPTED SWITCH FROM DPC” BSOD (Blue Screen of Death) error may appear when the computer abruptly shuts down during the initialization process for older versions of Windows, such as Windows Vista, XP, 2000, 7 and 8. This error is caused by a delayed procedure call (DPC) routine that attempted to perform an illegal operation. The DPC is triggered when the kernel detects a hung condition and makes a call to terminate or interrupt a software. It means that a yield, attach process, or a wait operation was executed from […]

The “AGP GART CORRUPTION” BSOD (Blue Screen of Death) error is an abrupt shutdown of the computer that results from a bug or an improper memory access by the device driver that utilizes the Direct Memory Access (DMA). This BSOD error means that the GART (Graphics Apperture Remapping Table) has been corrupted, resulting in the shutdown of the computer to prevent data loss. This BSOD error is often due to incompatibilities with installed device drivers and malfunctioning hardware, particularly recently installed devices before the error occurred. This BSOD error is […]

The “AGP INTERNAL”BSOD (Blue Screen of Death) error appears on the computer screen when the Accelerated Graphics Port (AGP) detects a problem with an installed video device or driver. The AGP functions as a channel that attaches the motherboard of the computer to the installed video card, and helps to accelerate 3D video graphics. The computer implements the automatic shutdown to prevent the loss of important data. This BSOD error is usually associated with drivers that are outdated, corrupted, or incompatible with the installed video adapter. It is also caused […]

The “BOOTING IN SAFEMODE NETWORK” BSOD (Blue Screen of Death) error may appear during the initialization process for Windows XP, Vista, 2000, 2008, and Windows 7 and 8. It means that the computer boots in the Safe Mode and with Network services, but many other services are unavailable. It shutdowns the system and forces a reboot to prevent damage and data loss. The BSOD error is usually caused by damaged or a corrupted files, such as damaged system files that result in startup errors. Corrupted system files result from the […]

The “AGP ILLEGALLY REPROGRAMMED” BSOD (Blue Screen of Death) error is an indication of the unauthorized reprogramming of the Accelerated Graphics Port (AGP), and usually appears when there is a bug in the installed driver for a video device. It causes the computer to shutdown automatically, which results in the loss of unsaved data. The appearance of this BSOD error may also be due to a corrupted or outdated driver, or the installation of a driver that is incompatible with the system. It may also be due to the installation […]

Here’s how to fix this rare, but serious Blue Screen of Death error: INVALID_PROCESS_ATTACH_ATTEMPT.

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 “AGP INVALID ACCESS” BSOD (Blue Screen of Death) error may appear when the GPU (Graphics Processing Unit) or visual processing unit that accelerates the creation of images has performed an unauthorized manipulation or alteration in the AGP (Accelerated Graphics Port) memory. It is an indication of a bug or problem with the installed video driver, or outdated BIOS (Basic Input / Output System). In most instances of this BSOD error, the installed video driver is not tested properly, or is unsigned. This BSOD error or Windows Stop message results […]

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 […]

The “ACPI BIOS ERROR” BSOD (Blue Screen of Death) error may appear during the installation of Windows XP. This error message may also appear when you resume computing after a period of hibernation. In the first instance, the Advanced Configuration and Power Interface (ACPI) Basic Input / Output System (BIOS) being not compliant with ACPI prompts the error message. Differences between the ACPI in the operating system and in the BIOS affect the outcome of simultaneous read/write operations, and features like Plug and Play (PnP) and Power Management. In the […]

Crashes and other errors can be more than just a nuisance. They can slow your computer down, or in some cases, may even cause you to lose important information. There are some useful tools within Windows that can help you diagnose and correct these errors to help you get on with your activities in no time. The Event Viewer is one of Windows’ most vital diagnostic tools. The Viewer can display which errors occurred and help you find out why they occurred. It will also display the level of urgency, […]
