Computer abruptly crashes either at random intervals and will flash a blue screen with white writing with a coded error message and restart or display it until the computer is manually restarted.

*Software or device drivers may have a problem.
* A hardware device is malfunctioning , or was removed while Windows
was running, or does not fully support Windows. On older machines,
outdated BIOS information can also cause errors.
* Hardware or hard disk errors during installation of Windows.
* Corrupted startup files , hardware and driver software during Windows
startup can also be the cause. This type of error will always require
troubleshooting before Windows can start up normally.
* Intermittent errors that appear randomly. These can be caused by an
overheating processor, a defective memory system, a dying or dead hard
disk , or faulty software and device drivers.

Solution :
These are some of the most common Stop Messages along with their cause and suggested resolution:

Stop Code: STOP 0x0000000A
IRQL_NOT_LESS_EQUAL

Code Meaning : Faulty device drivers, or services from backup utilities or virus scanners
Recommended Resolution: Remove, disable or stop the offending drivers,
backup utilities or anti-virus programs. Get updated software from the
manufacturer.


Stop Code: STOP 0x0000001E
KMODE_EXCEPTION_NOT_HANDLED

Code Meaning: Some driver files may be causing a problem.
Recommended Resolution: Remove, disable or update the driverfile listed
in the error message. Verify if new hardware installation is correct.


Stop Code: STOP 0x00000024
NTFS_FILE_SYSTEM

Code Meaning: Usually caused by disk corruption in the NTFS file system or third-party disk defragmenters.
Recommended Resolution: Use hard disk diagnostic software to verify
that the hard disk is working. Remember to always Use
Microsoft-certified disk defragmenters.


Stop Code: STOP 0x0000002E
DATA_BUS_ERROR

Code Meaning: Caused by a parity error in the system memory. Almost
always caused by hardware problems: A configuration issue, defective
hardware, or incompatible hardware.
Recommended Resolution: If physical RAM was recently added to the
system, remove it and see if the error still occurs. If the error
persists, try disabling memory caching in the BIOS. Else remove, repair
or reinstall the defective hardware.


Stop Code: STOP 0x00000050
PAGE_FAULT_IN_NONPAGED_AREA

Code Meaning : Caused when requested data is not found in memory; the
system checks the page file, but the missing data is I dentified as
unable to be written to the page file
Recommended Resolution: Remove any newly-added hardware or run
diagnostic software supplied by the manufacturer to check if the
component has failed. Install updated device drivers or roll back to a
previous driver.


Stop Code: STOP 0x0000007B
INACCESSIBLE_BOOT_DEVICE

Code Meaning: Caused when Windows loses access to the system partition
during the Startup process. This can be caused by: an incorrect driver
for a SCSI, RAID, or UDMA IDE controller; incorrect ARC path in the
Boot.ini; or a failed boot device.
Recommended Resolution: Verify that the disk storage device is
installed correctly and working. Reinstall or update the device driver.
Verify that the BIOS setting for the device is correct. Verify the
integrity of the hard disk.


Stop Code: STOP 0x0000007F
UNEXPECTED_KERNEL_MODE_TRAP

Code Meaning: Caused when the CPU generates an error that the kernel
does not catch. Usually hardware related, especially RAM. Can also be
caused by CPU overclocking, or defective components on the motherboard.
Recommended Resolution:
 1. Run the memory diagnostic to test RAM.
 2. Restore over clocked settings to previous values.
 3. Repair/replace the motherboard.
 4. Disable sync negotiation in SCSI BIOS; check SCSI termination.


Stop Code: STOP 0x000000D1
DRIVER_IRQL_NOT_LESS_OR_EQUAL

Code Meaning: Occurs when the system attempts to access pageable memory at a process IRQL that is too high
Recommended Resolution: Very similar to STOP 0xA. Remove, disable or
stop the offending drivers, backup utilities or anti-virus programs.
Get updated software from the manufacturer.


Stop Code: STOP 0xC000021A
STATUS_SYSTEM_PROCESS_TERMINATED

Code Meaning: Caused when the user-mode subsystem (Win logon or CSRSS)
is fatally compromised and security cannot be guaranteed. The most
common causes are third-party applications or mismatched system files.
Recommended Resolution:
 1. Remove, disable, or roll back any newly-installed device driver.
 2. Uninstall any newly-installed software.
 3. Use Windows-compatible backup/restore programs.
 4. Restore full control permissions to the local SECURITY account on
the system root folder by doing a fresh parallel installation of
Windows on a separate partition.
