0x000000d1 what an error. How to fix DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen errors (0x000000D1)


The blue screen of death is an unpleasant and very diverse thing. The other day I had to look at another laptop with a constantly crashing BSOD with the error STOP: 0x000000D1 due to NETIO.SYS. And after that I decided to write an article, especially since I have encountered this problem more than once, so I think it will be useful.

The error usually occurs out of the blue. Without any warning, in the middle of complete calm, the BSOD screen appears, which you can see in the picture. This error is called in full STOP 0x000000D1 DRIVER_IRQL_NOT_LESS_OR_EQUAL. Small observations allow us to establish that it appears while working on the network. It is curious that the fix for this error for Windows XP and Windows Vista has long been described on the Microsoft website. Moreover, in Windows Vista even the file is called the same - NETIO.SYS. This system file implements the IPv4/IPv6 network stack on the system. For some reason, there is still no fix for Win 7. Let's try to cope on our own, using improvised means.

Oddly enough, in most cases this problem occurs when using the wonderful uTorrent program. Interestingly, only the program version 2.0 and older produces an error. Almost 90% of BSOD with error STOP: 0x000000D1 due to NETIO.SYS on the “seven” in my practice was associated with this program. In this case, the solution is simple - roll back the torrent client to an older version or replace it with a similar one. For example, I had no such problems with Vuze.

You can try to bring uTurrent to the version that you have installed. However, there is no guarantee of success. For some reason it didn’t always work out for me. In the program, go to Settings - Advanced. There we find the parameter net.dissable_incoming_ipv6 and change false to true. After that, just above we find the parameter bt.transp_disposition and change its value to 5. After that, turn off the program and turn it on again.

Sometimes it happens that an error with NETIO.SYS occurs without the participation of uTorrent. This is a slightly more complicated case. However, the cause of the error is still the same - incorrect operation of NETIO.SYS. Then we need to try to find the latest drivers for the network card we are using. After installing them, press “WinKey” + “R”. The “Run” window will appear. At its command line we enter: “sfc /scannow”, as in the picture. Theoretically, this should be enough.

And finally, if all of the above did not help, then disable Internet Protocol version 6 (TCP/IPv6), as in the picture. You can get to this window as follows: Start - Control Panel - View network status and tasks - Change adapter settings. From the list of adapters, select the one you need and right-click on it. From the menu select “Properties”. Then uncheck the same box as in the figure.

One of these methods will definitely work. Good luck to you!


Sometimes hardware-related DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen errors can be caused by corrupted random access memory (RAM). If you are experiencing random computer reboots, booting beeps, or other computer problems (in addition to BSOD 0xD1 errors), then it is highly likely that your memory is corrupted. In fact, almost 10% of application crashes on Windows OS are caused by memory corruption.

If you've recently added new memory to your computer, we recommend temporarily removing it to make sure it's not causing the DRIVER_IRQL_NOT_LESS_OR_EQUAL error. If this action resolves the BSOD, then this is the source of the problem, and therefore the new memory is either incompatible with some of your hardware or damaged. In this case, you will need to replace new memory modules.

If you did not add new memory, the next step is to run a diagnostic test on your computer's existing memory. A memory test will scan for hard memory failures and intermittent errors that could be causing your 0xD1 blue screen of death.

Although recent versions of Windows include a RAM test utility, I highly recommend using Memtest86 instead. Memtest86 is a BIOS-based testing software, unlike other test programs that run on Windows. The advantage of this approach is that the utility allows you to check ALL operating memory for DRIVER_IRQL_NOT_LESS_OR_EQUAL errors, while other programs cannot check memory areas occupied by the program itself, the operating system and other running programs.

Error 0x000000D1 is another blue screen of death, the very phenomenon that so frightens all users of Windows operating systems, even the most experienced of them.

By their nature, fixing most blue screens of death takes an incredible amount of time and your nerve cells. However, if you become “lucky” and see on the screen , then we have good news for you - this blue screen of death is a simple case and can be dealt with quite quickly.

First you need to understand the reason for the appearance of this blue screen. It just so happened that the simple blue screen of death has a simple reason for its appearance - incorrect drivers.

It is possible that you recently installed new drivers for some hardware component of your configuration. These drivers may have been incompatible with your system, damaged from the start, or they became corrupted when downloaded from a certain resource.

In general, the problem is faulty drivers causing conflict in the system. As a result of this conflict, the system crashes and on the screen you see a blue screen of death with an error code .

Great, now that we are familiar with the cause of such a problem as error 0x000000D1, let's look at methods on how to get rid of it.

To solve this error, you do not need to download any third-party software. All you may have to download are other drivers to replace the faulty ones and one small patch from Microsoft.

Having learned that the cause of the blue screen of death is a faulty driver, you probably thought, “How can I figure out which driver is causing the blue screen of death?”

The answer to your question can be found on the Blue Screen of Death itself. In most cases, it indicates a specific driver that caused a conflict in the system and a crash in it.

Here's a list of some drivers to give you an idea of ​​what you'll be dealing with:

  • nv1ddmkm.sys- if you see a similar name on the screen with BSoD, then you have problems with the drivers for your Nvidia video card.
  • atikmdag.sys— a problem with the drivers for the ATI Radeon video card.
  • rt86win.sys- this name indicates a problem with Realtek drivers.
  • ndis.sys- and here you are already dealing with faulty drivers for your network card.
  • and so on.

The note: the whole point lies in the initial letters of the name of the designated drivers, i.e. nv=Nvidia and similar analogies. Just enter a name you are not familiar with into a search engine and you will definitely find the information you need about the driver.

Now let's look at what will help you get rid of the blue screen of death error code .

Method #1 Update drivers

First of all, perhaps, you should try to simply update the drivers, i.e. replace those that are incompatible with the system. What and how to update depends on which drivers you are having a problem with.

You can try updating your drivers through Device Manager. To do this, do the following:

  • "Start" "Device Manager".
  • Find the hardware you need whose drivers you need to update.
  • Right-click on it and select the item from the context menu "Properties".
  • Go to the tab "Driver".
  • Click on the button "Update" and then select the Internet option.

Or go to the website of the manufacturer of the equipment you need, go to the downloads section, download drivers and install them. Then test the system and see if the Blue Screen of Death appears with an error code . Well, is the problem still there? Then let's move on.

Method No. 2 Roll back drivers to a previous version

If the update did not help, it’s time to start rolling back drivers to a previous version with which the operating system worked normally. To roll back drivers you will have to go to Device Manager again:

  • Right click on "Start" and select the item from the context menu "Device Manager".
  • Find in the list of devices the device whose driver you want to roll back to the previous version.
  • Right-click on the device and select from the context menu "Properties".
  • Then go to the tab "Driver".
  • Click on the button “Roll back.”
  • Click “Yes” on the warning window that appears.

Method #3 Special patch package

If you own the Windows 7 or Windows RT operating system, you can try installing one small patch package from the developers themselves.

All you need to do is follow this link, download the patch and install it. This patch update for the above operating systems is specifically aimed at fixing an issue such as the error . After installing it, you will surely be able to get rid of this blue screen of death problem.

Method #4 System Restore

If none of the above helps you, and this is unlikely, but still not impossible, you can try a system restore. This step is always the most effective and will allow you to reverse all changes that have been made in the near future in the operating system.

To start the system restore process, do the following:

  • Right-click on “Start” and select “Control Panel” from the context menu.
  • Select “Recovery”.
  • Start the system rollback process by selecting the desired restore point.

After performing System Restore, blue screen of death and error will probably have to disappear, since previously introduced changes to the system will be canceled. But if even System Restore did not help, for some reason, then the only option in this case is a complete reinstallation of the operating system.

Found a typo? Select the text and press Ctrl + Enter

Errors of this kind can be caused by unknown reasons. In almost all articles about BSoD I say that the cause may be software or component failure, and this article is no exception.

What was the reason for the error to appear? DRIVER IRQL NOT LESS OR EQUAL? I usually use the Google Chrome browser, but I also like Microsoft Edge because it's pretty fast. I open Edge and the system crashes, a blue screen appears with the error DRIVER IRQL NOT LESS OR EQUAL. After rebooting the system, I tried to launch the browser again and again the error occurred.

How did I get rid of 0x000000D1?

I didn’t suffer for long, because I suspected what the problem might be. Literally in the morning the browser was working, and then this happened. In general, I installed the Adguard utility - an ad blocker in browsers. It turns out that it installs extensions in all browsers, and since at the moment it only supports a couple of extensions, I thought that some kind of conflict had occurred, which is why the “screen of death” appeared.

After removing Adguard, the Edge browser started to run smoothly.

I didn't even have to analyze the memory dump to determine the cause. Most likely yours is different, so I advise you to read the article and identify the causes of blue screen errors.

On the Internet, many people get the same error and each has different reasons, but as I understand it, it’s all because of the software. Perhaps you installed something recently, then delete it. You may need to update some drivers, so do that.

Of course, there are standard recommendations for fixing BSoD, but they may not help. For starters, you could try using them. But you will definitely have to use memory dump analysis; you want to get rid of the error, right?

  • Scan the system for viruses;
  • It is recommended to free up the system disk so that it is not filled to the red zone;
  • Windows developers are working to release updates that will help get rid of BSoD in the future. Install updates through the “Update Center”;
  • If an error occurs due to updating or installing a new driver, it is recommended to roll it back to an earlier version. Newly installed programs will have to be removed, as they can also be the culprits of blue screens;

  • The last point is to reinstall the operating system (most often it helps).

    • OK it's all over Now. These are the kind of unpleasant things that can happen to your computer, but you can fix them, even if you have to work hard. I repeat, once again, do this and you will be able to identify the cause of the blue screen.

    BSoD errors have always scared users more than others. The display of a “blue screen of death” indicates serious errors that prevent the system from continuing to function and the correction of which is required urgently.

    The most common error code is 0x000000D1, which indicates problems with the driver.

    How to fix the error

    To begin with, in order to try to correct the situation in question, you need to clearly understand which driver started to malfunction. If the description refers to the .sys file, then you can figure out on your own which hardware Windows is complaining about:

    If the first letters in the file name are nv or ati, then this problem is probably related to the NVidia and AMD video card drivers respectively.

    To solve this problem, you need to update your video card drivers. To do this, download the installer corresponding to your video card from the official website and reinstall it. If you have a laptop or a built-in video card on the motherboard (processor), the software can be downloaded from the websites of the manufacturers of these products.

    If the first letters of the file name are rt, then this will indicate that the audio card drivers are “quarreling”.

    In this case, the best option would be to download the software from the motherboard manufacturer’s website. Then you need to reinstall it. If the audio card is discrete and not built-in, in this case, download and reinstall the software from the website that manufactured this equipment.

    The ndis.sys file indicates a network card driver error.

    To do this, we reinstall them by first entering Windows safe mode without loading network drivers.

    If none of the above points correspond to your problem, look for the name of the file in search engines and try to find out for yourself what equipment uses it.

    If the source of the problem is not displayed, download and install BlueScreenView. It will help with the issue of finding out the names of the problematic files, and after that, begin solving the problem of a particular driver.

    The problem can also be solved using standard Windows OS tools. To do this, go to the “Boot and Recovery” window (can be found by searching in the OS) and check the box next to “Write to system log”.

    If you don’t want + and carry out such manipulations, use the official Microsoft website and download a separate application that will help solve this problem (
