How To: Fix Windows Stop Error “Stop 0×0000000A or IRQL_NOT_LESS_OR_EQUAL”
Windows Stop Errors literally mean that Windows operating system has stopped or terminated. These only appear in NT based operating systems such as Windows NT, 2000 ,XP and also in Windows Vista. Most of the time these Windows stop errors are caused by hardware problems and conflicts. A Windows stop error looks like a Blue Screen (BSOD-Blue Screen of Death) with a code below it saying something like which is the computers way to tell you what is wrong.
“Stop 0×0000000A or IRQL_NOT_LESS_OR_EQUAL”
Technically, this error condition means that a kernel-mode process or driver tried to access a memory location to which it did not have permission, or at a kernel Interrupt ReQuest Level (IRQL) that was too high.The IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0×0000000A. This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
Parameters of Windows Stop Error
The following parameters are displayed on the blue screen.
1 Memory referenced
2 IRQL at time of reference
3 0: Read1: Write
4 Address which referenced memory
Causes of “Stop 0×0000000A or IRQL_NOT_LESS_OR_EQUAL”
This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.Stop 0×0000000A or IRQL_NOT_LESS_OR_EQUAL error 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.The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version.
To resolve an error caused by a faulty device driver, system service, or BIOS
- Restart your computer.
- Press F8 at the character-based menu that displays the operating system choices.
- Select the Last Known Good Configuration option from the Windows Advanced Options menu. This option is most effective when only one driver or service is added at a time.
To resolve an error caused by an incompatible device driver, system service, virus scanner, or backup tool
- Check the System Log in Event Viewer for error messages that might identify the device or driver that caused the error.
- Try disabling memory caching of the BIOS.
- Run the hardware diagnostics supplied by the system manufacturer, especially the memory scanner. For details on these procedures, see the owner’s manual for your computer.
- Make sure the latest Service Pack is installed.
- If your system has small computer system interface (SCSI) adapters, contact the adapter manufacturer to obtain updated Windows drivers. Try disabling sync negotiation in the SCSI BIOS, checking the cabling and the SCSI IDs of each device, and confirming proper termination.
- For integrated device electronics (IDE) devices, define the onboard IDE port as Primary only. Also, check each IDE device for the proper master/subordinate/stand-alone setting. Try removing all IDE devices except for hard disks.
If you encounter a Stop 0xA message while upgrading from Windows XP to Vista, the problem might be due to an incompatible driver, system service, virus scanner, or backup. To avoid problems while upgrading Windows operating systems, simplify your hardware configuration and remove all third-party device drivers and system services (including virus scanners) prior to running setup. After you have successfully installed Windows Vista, contact the hardware manufacturer to obtain compatible updates.
