When Windows auto-installs an update for the HID Keyboard Device, by default the same automatic update alter the keyboard class code and end the user with the “DRIVER IRQL NOT LESS OR EQUAL (kbdclass.sys)” error. Follow the on-screen instruction to complete the process.

Your System will further identify, download, and install the Driver’s latest version (if available).

Now on the next screen, click on the first option, i.e., Search automatically for updated driver software.

Here from the keyboard drivers list, right-click on the device name mentioned there and then select the option Update Driver from the sub-menu.

Now on the Device Manager window, locate and expand the option Keyboards.

Firstly, press WINDOWS + X and select the option Device Manager from the context menu.

Does anyone have an idea what could cause my PC to reject every aftermarket driver I throw at it? But only when I'm gaming and not during stress testing. Thinking my OC was at fault (i5-6600k at 4.6 GHz on Maximus VIII Ranger) i ran both aida64 stress test and unigine heaven to verify that Brother my GPU nor CPU were the issue.Īnd now to the weird part - both programs ran stable for over 24 hours consequtively and simultaniously. Since then I installed Daemon Tools lite on my machine (which by the was requires a driver installation) and again ran into another driver violation. Trying Avast and AVG after that led me to the conclusion that there had to be some other cause than the individual peaces of software.

I then tried switching to Bitdefender for my security but I encountered the same issue. Using driver verifier i was able to identify the drivers causing the issue -it turned out to be the firewall driver of Kaspersky and some mouse driver for my Mad Catz R.A.T. I was recently getting some BSODs when gaming with error code DRIVER IRQL NOT LESS EQUAL.
