IRQL_NOT_LESS_OR_EQUAL From a Mouse Movement on Windows 11
Every time I move my mouse, my Windows 11 PC crashes with the dreaded IRQL_NOT_LESS_OR_EQUAL blue screen error, and this happens consistently regardless of which USB port I use or whether I'm using a wired or wireless mouse. I've already updated my chipset and USB drivers, run memory diagnostics, and checked for malware, but nothing seems to stop this crash from happening whenever I try to move the cursor.

The IRQL_NOT_LESS_OR_EQUAL error means a driver tried to access a memory address it didn't have permission for . The kernel (the core of Windows) detects this, panics, and throws the blue screen . Since you've already updated chipset and USB drivers, the culprit might be a conflicting mouse driver or its companion software.
Hi, that blue screen usually points to a kernel driver issue, not the mouse movement itself. I’d uninstall any mouse/vendor utility software, test with a basic mouse, and check the minidump file to see which driver is named. USB controller, HID, chipset, or security filter drivers are the most likely places to look.
