More information about the  Blue Screen of Death STOP Codes is written now.

0×00000012:TRAP_CAUSE_UNKNOWN

Error Analysis: If you encounter this error message, it indicates a trap from an unknown cause.

Solution: The Microsoft can not analyze the reason. What you can do is to think about when this error occurs and what you were doing with your laptop. Identify the possible causes for it, then take some related measures.

0x0000001A:MEMORY_MANAGEMENT

Error Analysis: This is a Windows 2000 Executive character-mode STOP message. It indicates a general memory management problem. For example, the newly installed hardware or memory itself has problems.

Solution: If this error message appeared on the screen during the installation of Windows, it may because that amount of RAM and disk space required to load the operating system is too small.
If this is the first time you have booted after installing new hardware, remove the hardware and boot again.
If you don’t do some installation, you can reboot your laptop with the recovery options set to create a dump file or select the Last Known Good option.

0x0000001E:KMODE_EXCEPTION_NOT_HANDLED

Error Analysis: It indicates that the Windows XP kernel detected an illegal or unknown processor instruction. The problem may be similar to that of the 0x0000000A.

Solution: It may be the system firmware you want to install is not compatible to your laptop,
If the blue screen message lists a driver by name, try to enter safe mode or Recovery Console mode to disable or remove the drivers listed on the blue screen.
If the stop message lists the file Win32k.sys, it may be caused by the by third-party remote control software. You should to disable it in the safe mode or Recovery Console mode.
If it occurs when you are trying to turn off some kind of software, you just need to upgrade or remove it.

0×00000023:FAT_FILE_SYSTEM
0×00000024:NTFS_FILE_SYSTEM

Error Analysis: 0×00000023:FAT_FILE_SYSTEM which indicates a FAT file system problem. And 0×00000024:NTFS_FILE_SYSTEM indicates an NTFS file system problem. These two blue screen errors are likely caused by the disk itself which are damaged physically. They may be also because there is too much disk fragmentation and may be caused by virus scanners, backup programs too.

Solution: First, run \\”Chkdsk /r\\” in the command prompt to check and repair the disk errors, if there is a Bad Track on the report, try to use the hard drive vendor inspection tool to inspect and repair.
Second, disable all the software such as virus scanners, firewall and backup programs.
Third, right click C:\\winnt\\system32\\drivers\\fastfat.sys and choose the Properties option to see if the version matches the current system used by the Windows version.
Forth, install the latest Motherboard drivers and upgrade other drivers.

I think almost all of you have experienced that your laptop was displaying the Blue Screen error. But how many of you really know the meaning of blue screen with all its numbers and codes. And how many of you can read the Blue Screen of Death and then take some measures. Here I will show you how to read the Blue Screen of Death.

Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL

You may see this blue screen codes during or after the installation of Windows XP. The Stop 0xA message indicates that a kernel-mode process or driver attempted to access a memory location to which it did not have permission, or at a kernel interrupt request level (IRQL) that was too high. A kernel-mode process can access only other processes that have an IRQL lower than, or equal to, its own. This Stop message is typically due to faulty or incompatible hardware or software. you can see the following picture：

Stop: 0x0000000A (parameter1, parameter2, parameter3, parameter4)

The parameter1 indicates an error address, the parameter2 indicates a correct IRQL you needed to access the memory, the parameter3 indicates the type of access, and the parameter4 indicates the address of the instruction that referenced memory in parameter 1.

If you see this blue screen codes when you installed the Windows XP, the problem might be due to an incompatible hardware, system service, virus scanner.

You should make sure that the hardware you want to install is compatible to your laptop, you can check it on the “Check System Compatibility” topic on the Windows XP installation CD or DVD. Or you can just install the hardware what you need and regardless all the third-party device drivers and system services such as virus scanner.

If the hardware is compatible, you may have to check other hardware issues. For example, you can specify the Hardware Abstraction Layer (HAL), turn off features in CMOS settings, or you can remove all the adapters and disconnect all hardware devices. While I have to say that if you are not a professional, you had better not do these operations.

If you see this blue screen codes when you have already installed your Windows XP, the problem may be related to the third-party software or hardware you have installed. You can use the “Troubleshoot third-party software and hardware” section to deal with this problem, or you can delete and remove the software or the hardware.

There is no doubt that the failing or defective hardware will result in this error code, what you need do is to remove or replacing the hardware.

All in all, the Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL indicates an incorrect environment. And other blue screen of death stop codes will be written soon.
