How To Fix ‘DRIVER IRQL_LESS_OR_NOT_EQUAL Error’ Issue on Windows PC – Guide

One of the most common Windows stop codes is called IRQL_NOT_LESS_OR_EQUAL. This cryptic name refers to an interrupt request line (IRQL) that PCs use to signal events that require urgent attention or response. In fact, IRQL_NOT_LESS_OR_EQUAL (sometimes just called “IRQL”) is typically a memory-related error that occurs when a system process or device driver seeks access to a memory address for which it does not have valid access rights. Memory allocations for processes usually have an upper bound address, so the NOT_LESS_OR_EQUAL part refers to an attempt to access an address outside (greater than) that bound. This error triggers an operating system stop that crashes Windows and triggers what is known as the Blue Screen of Death or BSOD. Windows displays a stop screen while collecting forensic data in the background. When this capture phase is over, the PC will restart by default (unless you changed the settings to turn it off). This BSOD is shown as the opening graph for this story.
