How to fix the BSOD (BLUE SCREEN) error DRIVER_IRQL_NOT_LESS_OR_EQUAL on Windows 10

Windows operating systems have the largest coverage on computers around the world. And the biggest "coverage" they have when it comes to headaches caused to users.

Compared to macOS, an operating system running only on Mac or MacBook, Windows works on PCs and laptops produced by various companies. From DELL, ASUS, Lenovo and up to brands and models that have not heard more than two people, all of them can install a version of Windows.
So, we're dealing with the various hardware that the same operating system is installing. This is where most of the critical functionality and critical issues occur on Windows.

The biggest problems with Windows are those that end up with BSOD (Blue Screen of Death) and the user inexperienced he does not know what to do to solve the problem.

Today we will stop the blue screen error: "DRIVER_IRQL_NOT_LESS_OR_EQUAL"

As we can also guess from the general error code, "DRIVER_IRQL_NOT_LESS_OR_EQUAL"Or refer to driver issues.

Making a bracket, drivers are those programs (you do not imagine they have the graphical interface) what links the Windows operating system, the application, and the device it uses.
For example, as the sound application will work on a Windows operating system, you'll need a driver specifically created to link the operating system to the sound card or sound output device. Without this driver, you will not have sound on Windows. No system sounds, no music player or anything else.

Most of the time, for each sound card model, there is a dedicated driver available from the manufacturer.
It's just an example. Of drivers they also need: network card, Bluetooth, wireless card, mouse, keyboard, monitor and more.

In order to create an even better environment for Diverser errors, we also have many scenarios on Windows where the use of a hardware device is only possible with several "cascade" drivers.

Returning to our subject, "DRIVER_IRQL_NOT_LESS_OR_EQUAL"Is exactly the date of a driver that does not work properly. The operating system remains stuck with various "Blue Screen" versions:

  • "Your PC ran into a problem and needs to restart. We're just collecting some error info, and we will restrate it for you."
  • ":( Your PC ran into a problem and needs to restart We are just collecting some info, and then we will restart for you If you would like to know more, you can search online later for this error: Qcamain10x64.sys ."
  • "STOP 0x0000000A: IRQL_NOT_LESS_EQUAL - Qcamain10x64.sys"
  • "STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED - Qcamain10x64.sys"
  • "STOP 0 × 00000050: PAGE_FAULT_IN_NONPAGED_AREA - Qcamain10x64.sys"
  • "A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: Qcamain10x64.sys. "

The problem may appear "out of the blue" after a Windows 10 update when the wireless network board becomes active. That is, after you connected your laptop or PC to a wireless network.

Qcamain10x64.sys is a file that keeps the Qualcomm Atheros Driver, responding directly to wireless LAN connections.
There are scenarios where, following a Windows 10 update, this driver has less happy interactions with other Windows 10 dirves and system components, leading to system crash.

BSOD Error Resolution: DRIVER_IRQL_NOT_LESS_OR_EQUAL / Qcamain10x64.sys

Solving can be done in two variants. The simplest is in the scenario where the operating system starts up.

Method 1

1. Right-click on "this PC"Then click"Manage"

2. Click on "Device Manager"- You can find the option in the left-hand bar under:"computer Management"→"System Tools"

3. Go to "Network adapters"And right-click on the network driver. In our case: Qualcomm Atheros QCA9377 Wireless Network Adapter.

4. click 'Update Driver Software"

In the next step you have two options where you can update / change the driver. Either use automatic search in which Microsoft will look for and install the latest driver version for your device, or look in your computer or a compatible CD / USB driver.

After installing the new version, it is not necessary to restart the operating system. Everything should work normally.

Ideally there is a CD with the original drivers for the Windows 10 operating system. If you bought your PC or laptop when it was an older Windows, Vista or Windows 7, it is best to go to the manufacturer's support page and download / install the latest version of the driver.

Method 2

The worst part is when the Blue Screen appears before the full operating system starts, and the "1 method" is impossible to apply. In this scenario, the only option remains to run the Windows 10 operating system in "Safe Mode"

Starting in "Safe Mode" is based on your laptop model. Most models access a F8, F10 or F12 as soon as the manufacturer / brand logo appears.

After entering Safe Mode, follow the steps from "Motoda 1" to 3. At the next stage, right-click on the driver and click "Disable"
Restart the operating system, turn on the driver and update.

If the problem persists, you will need to save your original driver (on a portable (USB Stick)) made available by the device manufacturer and install it offline.
