Resolving The Stop Code driver_irql_not_less_or_equal Windows 10


Now we know which file is causing the crashes we can now resolve this error.  We now need to see if there is a update for the driver which uses the files that is causing the crashes.  First we need to see what version of the driver we are using.  To do this click on the windows 10 start menu and type in Device Manager and hit enter.



Next find the device you are looking for and right click on it and select properties. Then in the window that pops up click on the driver tab and take a look at the number next to the "Driver Version" Below we can see my Broadcom 802.11 Network Adaptor is using driver version 7.35.333.0.



Install a Newer Driver - Now we need to visit the Broadcom website to see if there is a newer driver we can download and install. If there is a newer version download the driver and install on to your system.  Reboot your system and hopefully the issue is now resolved.

Re-Install The Current Drivers - If you already have the latest drivers installed we will uninstall the current drivers and re-install.  Go in to device manager and find your device, Now right click on the device and click on uninstall. This will now uninstall the driver from your system.  When the uninstall has finished reboot your machine, then re-install the driver.



Use Old Driver - Still having stop code crashes? If yes uninstall the driver again, then see if you can download an older version of the driver for your hardware. It is possible the latest newest driver has a bug that causes the driver_irql_not_less_or_equal crashes.

Hardware Issue - If you are still having an issue it is possible the hardware itself has an issue. Can you replace the hardware just to test if it is the hardware causing the issue.

a black window will now open, in this window type in CHKDSK C: /f /r you will then get prompted y/n type in y and hit enter.  Your system will now reboot and run the CHKDSK, This program could take 20 minutes to 2 hours to run.

Run a Full System Virus Scan - It is possible you have a virus on your system which is causing this driver_irql_not_less_or_equal blue screen error. Make sure your local virus scanner is updated and run a full system scan.  When the scan has finished run a second online virus scan, I find this scanner very good.

Run a SFC Scan - This scan will check all of the windows 10 operating system files or issues and will fix if it finds any. To run this scan click on the windows 10 start menu and type in CMD then right click on command prompt and right click the mouse and select "Run as administrator" In the black window type in  SFC /scannow and hit enter
