I fixed it, it was an intel modem driver which was installed…. Well I am not using any intel modems lol … Think it was clashing with my inbuild wifi adapter
The answer is in your blue dump error, mostly all dump error shows you the driver file name which creating the problem like xxx.sys or xyz.sys whatever it called and that .sys file name will help you to find out that drivers full name and after that it’s easy to download that corrupted drivers.
If your error doesn’t show you any .sys file then skip this “.sys driver name searching” step and move on to next step ‘Driver Download’ because now you’ll have to download and update all of your drivers in order to fix this problem.
After finding drivers file name on your blue screen error or maybe on the dump file, then it’s time to find that driver file on the drivers directory to get the full name of that particular drivers and here’s a great website where you can easily find your driver’s name by searching the .sys drivers file name in it.
So open the link given below and search for your driver’s name.
Drivers Directory -> http://www.carrona.org/dvrref.php
In my case, my corrupted drivers name is “rtwlane.sys” and after searching it on carrona.com, I got the full description about my drivers file which is creating the problem as you can see below.
After searching your drivers file on the Carrona.com you will need to find out what type of drivers it is yours. There are two types of driver, first windows based and second hardware based.
As you can see on above image there are two types of drivers installed in our computer.
- Hardware based drivers – Drivers name also listed with external driver source website.
- Windows based drivers – Drivers name listed with windows update(In Red Colour)
One of them or maybe both can be the cause of this stop 0x00000d1 error. So, now according to your “drivers name” move to our next step and in that, I’m going to show you how you can download both types of drivers easily.
As I mention above if your error doesn’t show you any .sys file name then you should directly move on to our next step download drivers because you’ll need to update both of your windows & hardware drivers to fix your problem.
Mostly Corrupted Drivers File Names –
- athw8x.sys – Atheros Wireless LAN Driver
- igdkmd64.sys – Intel Graphics driver
- tcpip.sys – Microsoft TCP/IP Driver (networking related)
- Netio.Sys – Network I/O Subsystem
- usbuhci.sys – UHCI USB Miniport Driver
- iaStor.sys – Intel Storage drivers
- rtwlane.sys – Realtek PCIEWireless LAN PCI-E NIC driver
Step 2 – Driver Download
Now download the drivers according to your blue screen error needs, if your error doesn’t show you any drivers file name on it then you’ll have to update both of your windows and hardware based drivers in order to fix your DRIVER_IRQL_NOT_LESS_OR_EQUAL computer problem.
Windows Based Drivers (Source Windows Update) – If you find your computer having a problem with your windows driver then you can update your windows drivers by “Windows Update Utility” provide by Microsoft in their Windows, but updating windows drivers won’t help you until you’ve download and install all the necessary updates given by the update center because windows drivers works together and need to get repair all of them if some of them got faulty.
Repairing all windows drivers is a very easy task to do and anyone can do that and you also don’t need to be a computer professional.
To update and repair your windows drivers you’ll just have to follow the given steps listed in that link below. So, open the link given below and repeat the solution 1 to 5 as shown in that tutorial.

Tried it and It is working fine since i did it. Thank you very much and keep it up.
If the problem still exists then the only things you can try to do is “reinstall your windows” and install latest drivers for all computer’s hardware devices after when the re-installation of windows completes.
