IRQL_NOT_LESS_OR_EQUAL BSOD

Renan Rhoden asked on

Hi,

I'm having some issues with my new laptop which is running Windows 8.1 PRO. Sometimes, when i try to turn it off, it simply appear a bluescreen with the code of IRQL_NOT_LESS_OR_EQUAL. When i run the bluescreen viewer it shows me what you can see in the image

it always happens when i try to turn it off randomly times. like now, i've been with my computer since i reainstalled the system from two weeks an it happened three time. it sucks because when a bluescreen appears, the computer restarts, and i am trying to turn it off.

It's no problem.

All of the attached DMP files are of the IRQL_NOT_LESS_OR_EQUAL (a) bug check.

This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.

This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high. The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.

FAILURE_BUCKET_ID:  AV_HIDCLASS!HidpCancelReadIrp

^^ The cause of the crash is consistently HIDCLASS.sys which is the Hid Class Library system driver (not the true cause).

aPs2Kb2Hid.sys is listed and loaded which is a Dritek System Inc. PS/2 KB to HID Device driver. If anything, this is very likely the cause of the crashes. I would check for an update to whatever this device driver is, or uninstall the software and remove the device ASAP.
