How do I fix driver IRQL not less or equal error?

Here are a few quick tricks you might try before heading to the solutions below:

Restart the computer and check if it now runs effectively. In some cases, it was a one-off issue that didn’t reappear. Remove any overclocking that you may have configured. If you used software for the job, uninstall the application. Check for Windows updates, and if any are available, download them. If you are connecting the USB devices using a hub, remove it, and plug them in directly. Also, remove all the non-critical devices and verify if that does the trick. Verify that the memory modules are correctly seated. Or, remove them and put them back in firmly.

If none of these work, the solutions underneath will.

1. Update your wireless adapter driver

According to users, you can fix this error simply by updating the wireless adapter’s driver. The process is a few steps long and requires an Ethernet cable to connect to the Internet. To download the latest wireless adapter driver, you need to disable the wireless adapter first. After disabling the wireless adapter, connect the Ethernet cable to your PC and download the driver. 1.1 Disable your wireless adapter 1.2. Download the latest driver

Even though this is the simplest way to update your drivers, it might not be the best since Device Manager doesn’t always download the latest drivers. For that, visit your wireless adapter manufacturer’s website and download the latest drivers. After installing the latest drivers, go back to Device Manager, and enable your wireless adapter. Also, similarly, update the graphics driver as well as the one for the Ethernet adapter, in case you have a wired Internet connection. SPONSORED

1.3 Update the drivers automatically

Suppose the method above didn’t work, or you do not have the necessary computer skills to update/fix the drivers manually. In that case, we strongly suggest using a professional tool specializing in driver updates. DriverFix scans your system and updates any outdated driver from its database of over 18 million driver files. Simple and fast, it will ensure every driver is installed correctly, with no errors.

2. Switch to Ethernet

A user pointed out that speed limitations could lead to the Driver IRQL_NOT_LESS_OR_EQUAL error in Windows 10. So, switch to a wired connection if you have a dongle or router that doesn’t support the speed delivered on the plan you are subscribed to. All you have to do is get the best Ethernet cable, plug it into the modem and the computer, and things will be good to go!

3. Test the memory

Issues with the RAM are another likely reason behind the Driver IRQL_NOT_LESS_OR_EQUAL error in Windows 10. So first, run the built-in Windows Memory Diagnostic, a tool that will scan for issues with the RAM and eliminate them. Since the former doesn’t carry out extensive testing, you can also go with MemTest86+, an open-source tool that looks for issues with individual memory modules and fixes them for good. Again, though, remember the device will take a few hours to run.

4. Reinstall the problematic application

If the OS crashes with the BSOD error only for a specific application, reinstalling it should do the trick.

5. Disable on-board graphics

If nothing else has worked, check if your computer has both onboard graphics and a PCI-E video card. If that’s the case, disable the onboard graphics, and the problem should be resolved. Again, though, it should be used only as a last resort to fix the Driver IRQL_NOT_LESS_OR_EQUAL error in Windows 10. And before you leave, find out the best BSOD fixing software to eliminate the problem in no time.
