A blue screen with an error and a description in the form of a stop code “STOP: 0x000000D1” is a very common phenomenon. For some reason, it is believed that this behavior of the system is mainly encountered by users of the seventh modification of Windows, although such a failure was noticed in systems of versions lower and higher. But, let's look at the example of Windows 7, what exactly could have caused this phenomenon. After that, we will determine the simplest ways to eliminate this error.
The reasons for the blue screen to appear in Windows 7 (0x000000D1) or in other modifications
Generally speaking, in technical language, the appearance of such an error can be triggered by an incorrect appeal of the software (driver) controlling the equipment to the failed unloaded RAM sectors at the IRQL process level.
Simply put, a conflict arises if it is not possible to load a driver or some program element for processing into RAM. But it's not only that. As it turns out, quite often the appearance of the “STOP: 0x000000D1” error is associated with the functioning of virtual memory, for which the paging file is responsible, as well as (which is generally surprising) with the incorrect operation of antivirus software, which, most likely, was installed bypassing the license or with using all kinds of hacking tools. Thus, based on the described reasons, we will look for the optimal solution to fix the STOP: 0x000000D1 crash in Windows 7. As mentioned above, the solutions proposed below can equally be applied to other similar systems.
Definition of a conflicting driver
First, let's focus on identifying a driver that could cause an error. If it was he who became the cause of the failure, along with the STOP: 0x000000D1 stop code, its name will be given at the bottom of the screen (usually these are SYS files). However, the file name may not always be displayed, so it should be determined independently. To get started, pay attention to the list of the most often “crashed” drivers:
- nv2ddmkm.sys, nviddmkm.sys, atismdag.sys - NVIDIA and ATI video card drivers
- rt64win7.sys and similar files - Realtek sound drivers;
- ndis.sys - network equipment drivers.
To determine the driver most accurately, you can not count on Windows 7 tools. To do this, it is best to use the BlueSecreenView utility, in which you need to click on the AppCrashView link, after which the failed software that caused the conflict will be shown.
The simplest methods to fix the error "STOP: 0x000000D1"
Now let's move on to fixing the failure. In the case of drivers, they must either be reinstalled or updated.
In principle, in the same “Device Manager” you can use the driver update item for the selected equipment, but at the same time, you should specify the search and installation of updated drivers. However, if they are found, anyway, the system will install them from its database. In this case, the search option is only preferable for compatible devices with a choice in the results of a third-party driver, not Microsoft.
You can also go to the sites of equipment manufacturers and download the latest drivers from them, using the device model name or VEN and DEV identifiers for searching, which can be found in the properties section by going to the information tab in the "Device Manager". After that, a search for drivers on a user computer or manual installation is specified.
In order not to engage in such operations yourself, it is best to install special programs to automatically update absolutely all the drivers available in the system. For example, the Driver Booster utility proved to be pretty good.
Note: if manual updating is nevertheless carried out, the installation of the network driver must be carried out without fail when loading the system in safe mode (F8 at startup).
Page File Actions
With the drivers, in theory, everything is clear. Now let’s look at troubleshooting with the STOP: 0x000000D1 code for the page file. It is believed that the appearance of an error indicates that its size is too small, which is currently installed in the system.
In this case, through the quick action configuration, its size can be increased to the recommended by the system or set to automatic configuration, giving preference to Windows. Please note that this applies only to cases where the amount of RAM meets the minimum requirements of the operating system. With large amounts of RAM (8 GB or more), the page file and the use of virtual memory can be turned off altogether.
Troubleshoot antivirus software issues
As for conflicts at the level of full-time antiviruses that were actually installed using hacking, only full reinstallation will help here, and only in the form of legal versions. By and large, today you can find a lot of free or shareware antiviruses. The same Kaspersky Lab offers a completely free package of Kaspersky Anti-Virus Free.
If you prefer Eset software products, you can install any antivirus with a free license for 30 days, and then re-activate the license every month (free keys are posted on the Internet all the time, and you can convert them to a license code on a special resource). A bit inconvenient, but you will definitely know that this is an official product, not a hacked one.
Physical memory corruption
Finally, the most unpleasant situation may be associated with damage to the RAM slots themselves.
You can check them using the special utility Memtest86 +, however, without special knowledge, an ordinary user is unlikely to figure it out. Therefore, you can apply a simpler solution focused on stationary PCs, which consists in removing the RAM strips from the slots on the motherboard one by one, each time rebooting the system. When an idle or bad strip is found (which can be guessed by the disappearance of the blue screen), it will have to be replaced or simply refuse to use it if the remaining volume meets the requirements of the operating system that are necessary for correct operation (even at least minimal).
