If the driver attempts to access a memory address it doesn't have proper access to, it can cause your system to crash. Drivers aid hardware communication, allowing your GPU to talk to the CPU, and so on. In this case, a piece of hardware is attempting to access a part of your system memory that it does not have access to because the CPU is processing other things. If too many bits of hardware attempt to communicate simultaneously, or rather, there is faulty configuration somewhere, the interrupt request level (IRQL) rises.


When your hardware wants to tell the CPU that something is about to happen, it makes an interrupt. The error indicates "that a kernel-mode driver attempted to access pageable memory while the process IRQL was too high."īreaking that cryptic message down, the error stems from a communication issue between your hardware and your processor. The DRIVER_IRQL_NOT_LESS_OR_EQUAL error relates to your system drivers and carries the stop code 0x000000D1.

What Is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Error? If you encounter this stop code, here's what to do. Windows 10 has a substantial array of error messages, and the DRIVER_IRQL_NOT_LESS_OR_EQUAL error is one of them.
