One of the most dreaded error messages for a Windows user is
the blue screen, or the Blue Screen of Death (BSOD) as it is popularly
known, which suddenly pops up informing you that
something is seriously wrong with Windows.The “Windows Stop Message”, which is the official name for the BSOD. What this screen essentially means is that Windows has crashed and needs to reboot to recover.
Additionally, the contents of the system memory(physical memory) are dumped to a file(%SystemRoot%\MEMORY.DMP). This memory dump file can be analysed to troubleshoot the problem in depth
All the stop errors are numbered according to the circumstances that caused
the error .Usually, you will be able to recover and continue
without any problems, but it can sometimes be a hair-raising
experience.
The blue screen of death can strike anyone, anywhere. At the Comdex trade show, Microsoft Chairman Bill Gates encountered the blue screen during a demonstration of Windows 98.
The BSOD is the main way for virtual device drivers to report a
problem. The error description will state that Windows faced a
problem (exception) at a particular memory address (a portion of
the RAM) in a certain file, usually with the prefix VxD (virtual
device driver), or the file name may have the DLL extension
Basic cause of blue screen of death-
1.faulty power supply
2.recent hardware or softwarte change
3.device driver problem
4.an overheating processor, a defective memory system, a dying or
dead hard disk, or faulty software and device drivers.
5.memory address conflict in RAM
6.faulty windows installation{hardware or hard disk error during installation} or
7.corrupted or crashed windows due to patch or may be due to malware
The basic approach-
obviously to correct the problem is - first we need to dignose the problem.
we can do it by seeing the list of probable causes or the blue screen error message{by the stop number}
The Stop number will be in hexadecimal format—something like this: STOP : 0x0000000A (0xDB000000, 0x00000001, 0x00000002, 0xB04FB0DB)
Notedown the stop number at first.If u r unable to note it down as windows reboot before it then u can :
clear the automatic boot check box at
rightclick my computer>properties>advanced system setting(vista)/advance(xp)>Advance>startup and recovery setting
Also if u r able to boot into sytem and run it nicely in safe mode{press F8 to do so at boot},then the problem lies
in some software rather than hardware
But If Windows is not
able to boot into Safe Mode, restart the computer, bring up the
Advanced Options screen (by pressing [F8] during POST) and select
“Last Known Good Configuration”. Windows will then attempt to
load the last settings where everything worked normally. If that
doesn’t work, then it most likely means you have a serious hardware
or critical startup system file error. If this error has occurred after
any recent hardware additions, remove the hardware and try to
boot again.
HOW TO SHOOT THE TROUBLE-
If you are able to boot into Safe Mode,
1.first perform a virus and spyware scan using a good antivirus or anti spyware
2.Uninstall any recently added software, and remove or roll back any
updated device drivers{u can do it in device management}
3.u may do System Restore
4.test the RAM for
errors by using a memory diagnostic program such as Windows
Memory Diagnostic
5.If the BSOD is caused by faulty hardware, remove any recently
added hardware—after switching off the PC, of course
6.If the BSOD is due to corrupt system startup files, you can repair
Windows by performing a Repair Install
Common Stop Message error codes and suggested solutions:
1.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.
2.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.
3.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.
4.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.
5.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
identified 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.
6.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.
7.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 overclocked settings to previous values.
3. Repair/replace the motherboard.
4. Disable sync negotiation in SCSI BIOS; check SCSI termination.
8.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.
9.Stop Code: STOP 0xC000021A
STATUS_SYSTEM_PROCESS_TERMINATED
Code Meaning: Caused when the user-mode subsystem (Winlogon
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 systemroot folder by doing a fresh parallel installation of
Windows on a separate partition.
