Are you facing irql_not_less_or_equal (0x0000000a) BSOD error in Windows 10? Well, this error is pretty severe, but, it can be fixable. IRQL stands for Interrupt Request Level, and it is related to the system’s processors. Though, the error occurs due to incompatible drivers or hardware malfunctions. Mostly when the user overclocks the CPU, then due to overheating Windows shows this BSOD error. So that your CPU can be saved from serious damage.

Many users also experienced IRQL NOT LESS OR EQUAL error, in the form of ntoskrnl.exe file. And, according to users, it was caused by the Realtek High Definition Audio drivers. ntoskrnl.exe file is also known as kernel image. Mostly when the driver IRQL error occurs, it appears with file details, which is causing the issue. So, if you have the name of that file, then you can fix the error by just renaming that file using CMD. However, I suggest you should try every solution mentioned in this article.

What are the causes behind this error?

There isn’t any certain cause behind this error. But, here are some general causes.

  • Buggy Device Driver.
  • BIOS update.
  • Peripheral Device. (faulty hardware)
  • Overclocking. (While gaming CPU overheating.)
  • Newly connected hardware part. (RAM upgrade.)
  • Some memory-related issues.
  • Windows Upgrade
  • updating BIOS

When a kernel processor device driver tries to access a memory location, which isn’t authorized to access. Then, the Windows os issue this error. Similarly when a software file is corrupted and tries to access the wrong memory address, then an IRQL error occurs. So, this was a short summary of what happened actually when the irql_not_less_or_equal error occurs. Now, let’s move towards fixing this blue screen error.

Note: Certain solutions I haven’t mentioned in this article, so do read my article on BAD_POOL_HEADER .

Uninstall the recent update.

It could be possible that the error is occurring due to recently installed system updates. So, to fix “irql_not_less_or_equal Windows 10” error. You need to uninstall the most recent update.

Steps to Uninstall – Open Control Panel, then go to Programs > Programs & features > Click on “View Installed Updates” (Check on the left side.)Uninstall Recent Updates - Getting Windows Ready

Update Outdated or Corrupted Device Driver.

After uninstalling the recent update and restarting the PC, if still an error occurs. Then, it could be a driver related issue. There are few drivers, which you need to update to fix this error.

  • Graphics Driver.
  • Ethernet and WiFi adaptor Drivers.
  • Disk Drivers.

Remove overclock settings  (Keep your computer cool)

Usually, laptop and PC generated lots of heat when it runs. And, if you’re not using any kind of cooling solution, then it will cause high CPU temperature. And, that leads to IRQL error in Windows. To reduce the temperature of your computer, upgrade your CPU fan. Though, usually in the summer season, the CPU fan doesn’t cool down the CPU. So it would be better if you install a CPU Liquid Cooler.

If you’re overclocking your CPU, then an overheating issue occurs. I suggest you install CPU Temp Monitor software. The computer manufacturer, does design computer components to use them to a limit. But, if you are using some overclocking software to boost your Computer performance while gaming. Then, this can be the main cause of the IRQL not less or equal error. Though, you can easily fix this error, by uninstalling that software and delete its settings. If you’re stuck in the BSOD error loop, then boot Windows in safe mode then uninstall.

Reinstall Windows or RESET Windows

If none of the above-mentioned solutions is working for you. And, the error is coming continuously, then you can do two things. The first thing you can do is “perform a system restore from safe mode”. And, if there is no system restore point created, and you’re using Windows 10. Then, first, create a backup of your important files in safe mode. After that, you can reset Windows, or can install Windows using a bootable USB Drive.
