Why IRQL_NOT_LESS_OR_EQUAL Memory Error comes in Windows 10?

The driver_IRQL_NOT_LESS_OR_EQUAL is the reason why BSOD popup on your screen when a memory address speculates unauthorized access, which can be a virus or malware. On further speculations, it could be a kernel_mode process or a device driver that tries to access the memory without the user’s permission. As any program in memory is known to be a part of its primary memory via pointers. The pointers come in coded values that are pointing towards its dedicated memory location. When these values of the pointer are corrupted or incorrect, then it causes an error by directing the application towards an unapproved memory location.

The reason behind an access violation is because of these errors in the user-mode program. However, in a kernel-mode, this creates a STOP “error oxoooooooA” message on the black screen of death ( BSOD ).

In the case of Windows 8.1, this error can be sourced right from the time of upgradation from Windows 8 to 8.1, and the reason behind this could be incompatible backup tools, driver devices, antivirus protection software, and in some case system software.

While making such changes in your system, always keep in mind to have a backup of data regularly to avoid IRQL_NOT_LESS_OR_EQUAL error.
