The blue screen of death is a fairly common and unwanted bug in Windows. To learn how to fix DRIVER IRQL NOT LESS OR EQUAL, this article will give you some instructions. This is a common blue screen error on Windows 10.

There are many reasons why an IRQL driver can be as bad or as bad as a BSOD. In most cases, however, it’s a problem with the network driver. In some cases, third-party antivirus programs or firewalls, such as. B. Bitdefender, Kaspersky, ESET, etc. cause conflicts so that such problems occur.

Hoe kan ik NIET-VRIJ OF UITRUSTINGEN IRROREN onder Windows 10repareren?

You have several options to get rid of this problem. I recommend that you use these methods one at a time.

Method 1: Update or reload the network drivers

Corrupt network drivers are the main culprits for these types of BSOD errors. For some users, the problem is with rt640x64.sys, a Realtek network adapter driver. So, since your first attempt to fix the IRQL driver is not inferior or equal, you should update it. If you don’t know how to do it, follow this article: How to update the drivers

However, for updating network drivers or other drivers, I recommend Driver Booster, Driver Easy, Driver Talent, etc. These tools can automatically and regularly update drivers and help keep your PC running smoothly. Above all, Driver booster has great features that allow you to do much more. It can also help you uninstall or remove drivers.

However, you can also reset the drivers manually. Please follow the instructions below.

  • First open the Start menu, type devmgmt.msc and press Enter.
  • Now expand the network adapters.
  • Then right click on the network drivers and go to their properties one by one.
  • Click on the Drivers tab and click Back.
  • Follow the instructions on the screen.
  • Then restart Windows.

This may solve your problem.

Method 2: Reinstall network driver

If the first method fails, try removing the network drivers. Then reinstall it to solve your problem. This might work for you. Please follow the instructions below.

  • First, open the Device Manager as in method 1.
  • Then expand the network adapters.
  • Then right-click on Network Driver and select Remove Device.
  • Follow the instructions on the screen.
  • Now restart the computer.

Windows will automatically reinstall the driver. If you are lucky, this will solve the DRIVER_IRQL_NOT_LESS_OR_EQUAL problem.

Method 3: Remove Epfwwfp.sys/bddci.sys (for Bitdefender/ESET antivirus users)

In some cases, the first two methods may not be successful. This is because your computer’s blue screen error is caused by something else. You can figure it out, but it will be a long process. The most common offenders are epfwfp.sys or bddci.sys. So you can remove them and see if that solves the problem. To do this, go to C:WindowsSystem32drivers and locate these .sys files. If you are using ESET, you will see epfwfp.sys. Bitdefender users see bddci.sys. Just delete it.

Some users may not have access to Windows. Because the IRQL DRIVER IR indicator cannot be free or equipped until the windows start working properly. In this case, you can boot into recovery mode and delete these files. Please follow the instructions below.

  • First, start in recovery mode. From there, you can follow the method or use bootable Windows media. In this case, insert the boot disk and select Repair Computer when the Windows installation window appears. Folgen Sie dann den Anweisungen unter diesem Link.
  • Make sure you have navigated to Troubleshooting > Advanced Settings > Recovery Mode command line.
  • Then follow these orders.

c:
cd Windows
cd System32
cd Driver cd

run bddci.sys bddci.sys.bak

or

run epfwfp.sys epfwfp.sys.bak

  • Now restart your computer. That should solve the problem.

Method 4: Disable or restart antivirus/firewall

Since you are still not sure of the cause of the BSOD, you can temporarily disable or remove the antivirus or firewall to see if it can help. You can also boot into clean boot mode to identify problematic programs and fix the problem.

Method 5: Analyze Mini-Ejection Record

The best way to determine the true cause of a blue screen death is to analyze the mini file. This will help in finding the root cause of the problem causing the BSOD. So, fixing DRIVER IRQL NOT FREE OR ECOLOGICAL could be a very good option. To analyze the minidump and find a corrupted conductor, follow the instructions in this article.

These are the most effective methods. If not, you can try disabling PageFile and see if that helps. As a last resort, you can reinstall Windows.
