Windows systems are notorious for crashing for any number of reasons and in a number of ways. Some of these crashes are mild and can easily be overcome simply by closing a nonresponding application or by rebooting the system. However, others are more serious and can bring the entire system to its knees. Microsoft calls these types of crashes "Stop errors" because the operating system stops responding. When a Stop error occurs, the GUI is replaced by a DOS-like blue screen with a cryptic error message followed by a code number. This screen is affectionately referred to as the Blue Screen Of Death, or BSOD for short.
n this article, I'll try to give an overview to analyze BSODs and extract the relevant troubleshooting information. I have coverder very common Windows XP BSOD errors. Do check the link to an article in Microsoft's Knowledge Base(http://support.microsoft.com/defau
Dissecting a BSOD
Although Stop errors can be caused by both hardware or software malfunctions, the most typical cause is a hardware malfunction. Each Stop error is accompanied by a specific error description and an eight-digit hexadecimal number error code. It may not be immediately apparent when you see a BSOD (mostly due to the shock factor that hits you when a BSOD occurs), but you can use the description and code to identify the type of error that is occurring. You just need to be able to identify the key parts of the message so you'll have a direction and focus for your troubleshooting expedition. The trick is in finding the relevant information on the BSOD.
STOP: 0x0000000A - IRQL_NOT_LESS_OR_EQUAL
STOP: 0x0000001E - KMODE_EXCEPTION_NOT_HANDLED
This Stop error indicates that indicates that the Windows XP kernel detected an illegal or unknown processor instruction.
STOP: 0x00000050 - PAGE_FAULT_IN_NONPAGED_AREA
This Stop error indicates that requested data was not in memory. The system generates an exception error when using a reference to an invalid system memory address.
(Psst .. The Resolution for this is ... very Easy !!
Restart ur sys go to safe mode, loginto Admini ac (if XP), Then go to MYCOMPUTER properties> ADVANCED> PERFORMANCE> VIRTUAL MEMORY > SET IT TO ZERO> Apply>OK>OK ... & thne go to Local DISC [C:], > Right CLick> Properties> Tools> Error Checking> Chk
the First BOX> Apply>OK > OK > Restart !! & then u can chnage the virtual MEM, Issue Resolved !! )STOP: 0x0000007B - INACCESSIBLE_BOOT_DEVICE
This Stop error indicates that Windows XP has lost access to the system partition or boot volume during the startup process.
STOP: 0x0000007F - UNEXPECTED_KERNEL_MODE_TRAP
This Stop error indicates a hardware problem resulting from mismatched memory, defective memory, a malfunctioning CPU, or a fan failure that's causing overheating.
STOP: 0x0000009F - DRIVER_POWER_STATE_FAILURE
This Stop error indicates that a driver is in an inconsistent or invalid power state during shutdown or standby or hibernate mode.
STOP: 0x000000D1 - DRIVER_IRQL_NOT_LESS_OR_EQUAL
This Stop error indicates that the system attempted to access pageable memory using a kernel process IRQL that was too high.
STOP: 0x000000EA - THREAD_STUCK_IN_DEVICE_DRIVER
This Stop error indicates that a device driver problem is causing the system to pause indefinitely.
STOP: 0x00000024 - NTFS_FILE_SYSTEM
This Stop error indicates that a problem occurred within Ntfs.sys, the driver file that allows the system to read and write to drives formatted with the NTFS file system.
STOP: 0xC0000218 - UNKNOWN_HARD_ERROR
This Stop error indicates that a necessary registry hive file could not be loaded. STOP: 0xC0000221
STATUS_IMAGE_CHECKSUM_MISMATCH
This Stop message indicates driver, system file, or disk corruption problems (such as a damaged paging file).
STOP: 0xC0000221 - STATUS_IMAGE_CHECKSUM_MISMATCH
This Stop message indicates driver, system file, or disk corruption problems (such as a damaged paging file).
Now that you have a good idea of how to dissect a BSOD and pull out the relevant pieces of information from all the gibberish on the screen, let's look at some of the more common BSODs in Windows XP. I'll only cover just a few of the BSOD conditions, but there are lots of possible Stop errors. For each BSOD I discuss, I'll provide a link to an article on the Microsoft Knowledge Base that covers that particular Stop error. (Since more than one article might address a Stop error, you may want to search the Knowledge Base if you discover that you need more information.)
This Stop error, which can be caused by either software or hardware, indicates that a kernel-mode process or driver attempted to access a memory location it did not have permission to access or a memory location that exists at a kernel interrupt request level (IRQL) that was too high. A kernel-mode process can access other only processes that have an IRQL that's equal to or lower than its own.
Troubleshooting a Stop 0x0000000A error in Windows XP
This Stop error indicates that indicates that the Windows XP kernel detected an illegal or unknown processor instruction. The problems that cause this Stop error can be either software or hardware related and result from invalid memory and access violations, which are intercepted by Windows' default error handler if error-handling routines are not present in the code itself.
Possible Resolutions to STOP 0x0A, 0x01E, and 0x50 Errors
This Stop error indicates that requested data was not in memory. The system generates an exception error when using a reference to an invalid system memory address. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop error.
Possible Resolutions to STOP 0x0A, 0x01E, and 0x50 Errors
This Stop error indicates that Windows XP has lost access to the system partition or boot volume during the startup process. Installing incorrect device drivers when installing or upgrading storage adapter hardware typically causes this Stop error. This error could also indicate a possible virus infection.
Troubleshooting Stop 0x0000007B or "0x4,0,0,0" Error
This Stop error indicates a hardware problem resulting from mismatched memory, defective memory, a malfunctioning CPU, or a fan failure that's causing overheating.
General causes of "STOP 0x0000007F" errors
This Stop error indicates that a driver is in an inconsistent or invalid power state. This Stop error typically occurs during events that involve power state transitions, such as shutting down, or moving in or out of standby or hibernate mode.
Troubleshooting a Stop 0x9F Error in Windows XP
This Stop error indicates that the system attempted to access pageable memory using a kernel process IRQL that was too high. The most typical cause is a bad device driver (one that uses improper addresses). It can also be caused by faulty or mismatched RAM or a damaged pagefile.
Error Message with RAM Problems or Damaged Virtual Memory Manager
This Stop error indicates that a device driver problem is causing the system to pause indefinitely. Typically, this problem is caused by a display driver waiting for the video hardware to enter an idle state. This might indicate a hardware problem with the video adapter or a faulty video driver.
Error message: STOP 0x000000EA THREAD_STUCK_IN_DEVICE_DRIVER
This Stop error indicates that a problem occurred within Ntfs.sys, the driver file that allows the system to read and write to drives formatted with the NTFS file system. (A similar Stop message, 0x00000023, exists for the file allocation table [FAT16 or FAT32)] file systems.)
Troubleshooting Stop 0x24 or NTFS_FILE_SYSTEM Error Messages
This Stop error indicates that a necessary registry hive file could not be loaded. The file may be corrupt or missing. The registry file may have been corrupted due to hard disk corruption or some other hardware problem. A driver may have corrupted the registry data while loading into memory or the memory where the registry is loading may have a parity error.
How to Troubleshoot a Stop 0xC0000218 Error Message
This Stop message indicates driver, system file, or disk corruption problems (such as a damaged paging file). Faulty memory hardware can also cause this Stop message to appear.
"STOP: C0000221 unknown hard error" or "STOP: C0000221 STATUS_IMAGE_CHECKSUM_MISMATCH" error message occurs

Hope my analysis will give a very short overview of BSOD's in WindowsXP. I want to give the entire credit to Mark Russinovich of Sysinternals.
