The main causes of the blue screen
--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machines, outdated BIOS information can also cause errors.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.
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 problemsa 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 relatedespecially 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.
