If you’ve been using your Windows 10 PC for a long time now, you might have come across a couple of issues – from minimal ones to critical ones like the Blue Screen of Death or BSOD stop errors. One of these BSOD errors you can encounter is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen error. This particular BSOD error is caused by iaStorA.sys, iaisp64 sys, Netwtw04.sys, nvlddmkm.sys, ndis.sys, wrUrlFlt.sys, and other driver files on Windows 10. This error indicates that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high. When you encounter this error, just like a typical BSOD error, your computer will abruptly stop and you will see a blue screen with an error message saying:
“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (100% complete)
If you’d like to know more, you can search online later for this error:
DRIVER_IRQL_NOT_LESS_OR_EQUAL (wrUrlFlt.sys)”
The iaStorA.sys file is a software component that’s related to the Intel Rapid Storage Technology by Intel. It is a software solution supported by Intel Smart Response Technology which allows the PC to communicate with the hardware as well as externally connected devices. The Intel Rapid Storage Technology enables the Peripheral Component Interconnect Express or PCIe storage support, serial ATA RAID or Redundant Array of Independent Disks 0, 1, 5, and 10 support, and the PUIS or power-up in standby is also supported.
To resolve this kind of BSOD error, you have to update, roll back or fresh-install the problematic driver. Refer to the options laid out below for detailed instructions.
The first thing you can try is to fix the Wi-Fi driver or the Ethernet driver on your computer to resolve the BSOD error. Take note that this option works not only on Windows 10 but also other Windows versions.
If you’ve already tried uninstalling the IRST driver but you’re still getting the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error when you use your Windows 10 PC, then this means that the drivers might be corrupted or not compatible with the operating system version that you are using right now. So to fix the problem, you have to update your drivers. To do that, follow the steps below.
Alternatively, you can also update the drivers via the Device Manager:
System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error. To run the SFC command, follow the steps given below.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

Error code 0xc00007b usually manifests itself via the inability to start an application properly. It can occur when users attempt to run a game or other programs on their computer. In such a case, the application will not start and a message box will pop up stating that error code 0xc00007b has occurred. The error code is likely to occur when users attempt to run a program in the incorrect or inappropriate bit. For instance, if you try to load a 32bit location with a 64bit location.
Error CausesError code 0xc00007b affects various versions of the Windows operating system, including Windows 7, 8, 8.1, and Windows 10. In the case of error code 0xc00007b for Windows 10, the error may be caused by issues related to software you’ve installed on your machine. This may cause software conflict resulting in the need to install programs like DirectX. Left unchecked, error code 0xc00007b could incite other error codes in Windows 10, such as error code 0xc004f034.
To repair error code 0xc00007b for Windows 10 devices, users will need to implement at least one manual repair procedure. Manual repair methods are effective in combating these issues as they can address the issues causing the error in the first place, thus fixing the problem.
The manual repair procedures for fixing error code 0xc00007b are very straightforward and can be implemented with little technical knowledge. However, you may need to contact a Windows repair technician if you have difficulty fixing the error code after completing the manual repair methods listed below.
Microsoft DirectX is an application usually included in the Microsoft operating system. It enables users to access high-speed gaming and multimedia on their PC. The latest version of this Windows technology is available on Microsoft’s official site.
Visit the Microsoft website and search for DirectX End-User Runtime Web Installer. Once you have located the latest version of the program, select the preferred language you would like DirectX to run in, and then click download. Run the program, then be sure to reboot your computer.
Note that this solution should only be applied if you are having issues running or displaying a gaming or multimedia application. Once you’ve correctly installed the latest version of DirectX, it should be able to fix underlying issues that may be causing error code 0xc00007b to occur. If you are still unable to run applications after completing this manual repair procedure, however, you will need to apply another method to fix error code 0xc00007b for Windows 10.
.NET Framework, a framework developed by Microsoft, provides solutions for users who may be having problems with applications. To download the latest version of the .NET framework, follow the steps listed below.
To ensure you successfully download the latest version of the .NET Framework, verify your computer is properly connected to the Internet while downloading the software. Also, follow the instructions provided on the Microsoft website.
After completing the download process, reboot your computer then check if you have successfully resolved error code 0xc00007b for Windows 10. If this manual repair method is successful, you will be able to access your gaming and multimedia programs. Otherwise, the error code message box will reoccur, stating that the application error code is present on your device. Apply the next manual repair procedure to correct the error code if this reoccurs.
In certain instances, application error codes like error code 0xc00007b affect PC users who fail to install the most current Windows updates on their device. That is why it’s important to check your system and ensure you have installed all the latest updates.
The updates, if any are available, will automatically be installed on your PC once you access Windows Update in Settings. Reboot your computer then check if you are able to run programs that previously would not open due to error code 0xc00007b. If problems persist resulting in the reoccurrence of the error code, reinstall the applications you are unable to open or get help from a Windows repair technician.

Error Code 45 is a common device manager problem that users encounter on any Windows 2000 and later operating system versions.
The error occurs when your Windows system fails to acknowledge the connected device by either stating that the device is not present or that it was previously attached to a computer.
The error pops up and appears on your computer screen with the following message:
“Currently, this hardware device is not connected to the computer” (Code 45)
Error CausesThe error is prompted either due to a temporary system file malfunction or a problem in the Windows registry system files. In the latter case, it could be due to a damaged or corrupted Windows registry.
While it may appear that Error Code 45 is a serious threat to your computer, it cannot be farther from the truth. Error Code 45, unlike other error codes, is the easiest one to fix. Here is how you can do it.
Unplugging and plugging the USB cable of the device into the computer is the easiest way to solve the error.
Doing this will help refresh the system and increase the likelihood of the device driver files loading and function properly.
It is often only a case of reconnecting the device back to your computer which helps eliminate the error and does not require any particular resolution other than this.
