To do this, you must inspect whatever cable plugged in your Windows 10 PC first. See if they are properly connected or not to your PC. Then, you will need to unplug each one of them properly. After you successfully unplug each one of the cables, you can proceed to reboot your Windows 10 PC. 

Once your Windows 10 PC turns back on, you can plug in all the cables back. Then, you can see if they are still disabled or not. If they are still disabled, then you can enable each one of them back. Make sure to plug in each one of the cables separately. Do the same thing if you want to enable the devices as well. Then, you can try to use each one of the devices once you successfully plug each one of them in.

In case none of the devices trigger the irql_not_less_or_equal error on your Windows 10 PC, then you can continue to operate your computer. If the plugged devices turn out to cause the error, then you can fix the said device at once. Proceed to get into the Safe Boot and uninstall the said driver completely. Afterward, you can download the latest version of the driver from the official site and install it.

Refreshing or Restoring Windows 10 System

The newest version of Windows includes a feature where you can refresh the system. The refreshing option allows you to reset every single setting of your device to default. Unlike the clean installation, the refreshing feature will not change all of your personal settings on your computer.

Due to the variety of issues which may cause the irql_not_less_or_equal error, you may find it difficult to determine the method to fix it. If you wish to end the irql_not_less_or_equal error at once, you can perform a system restore. Because of the multiple installations of third-party programs, it must be difficult to check which one of them causes the irql_not_less_or_equal error to happen. The solution to this problem is to restore the system back to its previous state.

For this method to work, you will need to create a restore point first. Once you do so, you can engage with the rest of the steps that follow.

Have you created a restore point yet? If yes, then you can follow the steps below to perform the system restore method.

  8. After you decide which point you wish to get the Windows system to back to, you can click on the option “Next”.
  9. Then, you can click on the Finish option.
  10. At last, you can close the windows and begin restarting your Windows 10 PC.
  11. At once, the restoring process will begin.

Alternatively, you can follow the steps below to perform System Restore on your Windows 10 PC.

  1. Proceed to go to Settings first.
  2. Then, you can head to the “Update & Security” section.
  3. Afterward, you can choose the option “Recovery” under the left pane.
  4. Next, you can select the option “Get Started” under the option “Reset this PC”.
  5. Then, you can select the option “Keep your files”.
  6. Proceed to follow the instructions on the Windows 10 PC’s screen to complete this method.

Performing Clean Windows Install

When all else fails, you can always perform a clean Windows install. If you cannot find the problematic driver which causes the irql_not_less_or_equal or driver_irql_not_less_or_equal error to happen on your Windows 10 PC, then you can try to tweak a few settings in the system. In case the system restore or the registry repairing does not fix the irql_not_less_or_equal or driver_irql_not_less_or_equal error, then you must make sure to refresh the system on your Windows 10 PC. When the refreshing feature fails too, you can perform a clean Windows install.

In order to perform this method, you will need an external hard drive to store the Windows installation media. Then, you can delete everything in your C: drive and get the fresh Windows 10 system back anew.

Make sure to perform this method only as of the last resort. If you still have important data stored in your local Windows disks, then you can try to perform the methods we have mentioned above. Once you perform a clean Windows install, then you will get everything anew with no trace of the programs or third-party applications within the system.
