Troubleshooting Windows Stop Errors: What they mean (in english)

Windows Stop Errors literally mean that Windows has stopped. These only appear in NT based operating systems such as Windows NT, 2000 and XP. Most of the time the errors are caused by hardware problems. A stop error looks like a Blue Screen with a code below it saying something like  “Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL” which is the computers way to tell you what is wrong. Here is a list that will tell you what those stop errors mean:

This list here is not a complete list, this only explains the most common ones. If your computer is restarting too quick to see the stop message you can make it not reboot by following the steps in This Article.

Stop 0x0000000A: IRQL_NOT_LESS_OR_EQUAL – This Windows stop error indicates that a kernal mode process or driver tried to access a memory location that it did not have permission to access, or at a IRQL that was too high (a kernal mode process can only access a IRQL that is lower than or equal to its own IRQL.

This stop message usually means that there is incompatable or faulty hardware. In personal experience its usually bad ram.

Stop 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL – Note the “Driver” part at the start off the message, this isnt the same as the error message above – This Windows stop error indicates that the computer tried to access memory using a kernal process which had a IRQL that was too high (as kernal processes can only access IRQLs that it is either equal to or  IRQLs that less than it). This is usually caused by incorrect or incompatible drivers.

Stop 0×00000024: NTFS_FILE_SYSTEM – This Windows stop error typically indicates that a problem occured with the file NTFS.sys such is the driver that allows the operating system to read and write to NTFS formatted harddrives. This can often be caused by harddrive problems.

Stop 0x000000ED: UNMOUNTABLE_BOOT_VOLUME – This Windows stop error is causes by a Input/Output sub-system tried to use the boot volume but failed. This error can occur during an upgrade to Windows XP Professional on computers that use faster ATA harddrives or have controllers with the wrong cabling.

Stop 0×00000050: PAGE_FAULT_IN_NONPAGED_AREA – This Windows stop error indicates that information that the operating system was looking for was not found in memory (ram).  This occurs when the system looks for information in the ram that doesnt exist. This is usually caused by defective RAM (once again, including Ram on your motherboard, L2 cache and video card ram).

Stop 0x0000002E: DATA_BUS_ERROR – This Windows stop error indicates an error in the system memory. It is caused when the system tries to access a memory address that doesnt exist. This usually is caused by defective or failed RAM (including those on your motherboard, Level 2 case or the memory on your video card). This can also indicate harddrive damage caused by viruses or other computer problems.

Stop 0x0000007B: INACCESSIBLE_BOOT_DEVICE – This Windows stop error indicates that Windows XP Professional is unable to access the boot volume or system partition of your harddrive during startup. Installing incorrect drivers for your harddrives or updating the storage adapter hardware usually causes this error. It is also possible that the boot volume or system partition was damaged by a virus infection.

Stop 0x000000EA: THREAD_STUCK_IN_DEVICE_DRIVER – This Windows stop error indicates that there is a problem with a device driver (such as the video card driver) that is causing the system to pause infefinitely. This problem is usually causes when the video card driver is waiting for the video card hardware to become idle but never does. This usually indicates that there is a hardware problem with the video device or the video card driver is faulty.

Stop 0x0000008e: PAGE_FAULT_IN_NON_PAGED_AREA – This is typically caused by faulty RAM or the RAM configuration you are running is incompatible with Windows XP.

Stop 0×00000044: MULTIPLE_IRP_COMPLETE_REQUESTS – This problem is primarily limited to Windows 2000 as is caused by a bad driver called “falstaff.sys”. This can be stopped by updating this driver from the vendor Here.

This list is limited and only explains the more common Windows stop errors. To search for more stop errors and have more detailed repair instructions you can search the Microsoft Website
