Part 1: What is the Bluescreen 0x000000ef Error?


Also called "Critical Process Died," error 0x000000ef is a boot error that prevents the operating system from starting, so a blue screen with blank letters is displayed before you can see your startup screen. This error occurs because a program inherent to the operating system stops working, making it impossible for you to use Windows.


This problem has been around for a long time, the first case occurred in Windows Vista, which is a version of the Windows operating system that was installed in 2006.


Part 2: Causes of Bluescreen 0x000000ef Error


The causes for the bluescreen 0x000000ef error to be generated are very diverse, however, most of the time it is due to two main factors:

1) Bad Device Drivers on Misconfigured Windows Service:

Drivers are small software that connects the operating system, in this case, Windows, with the hardware components of your PC. The driver instructs the operating system on how certain hardware should work and how the system must work together for the best results. If a driver fails, is not properly installed, or is not updated, the boot system will not function properly, and may throw the bluescreen 0x000000ef error.

2) Corrupt system files:

A corrupt file is one that has the original data modified due to a write or read error mainly. It can also be due to a virus or malware and even a damaged storage unit. Sometimes some of the operating system's own files may be corrupted, a situation that prevents Windows from working properly and consequently the bluescreen 0x000000ef error appears.


Part 3: How to Fix Bluescreen 0x000000ef Error


Even though bluescreen 0x000000ef error looks bulky, there are several ways to fix it. Below, I will show you some alternatives that will help you stop bluescreen 0x000000ef error:

Solution 1: Run a Clean Boot

A Clean Boot allows your Windows operating system to start with the least number of drivers and startup programs, in this way you can realize if any background program affects the correct operation of your computer. This feature is similar to Windows Safe Mode, but the Clean Boot allows you to have more control over the services that run at startup to help detect and isolate the cause of the problem. To perform a Clean Boot, you just have to follow the steps below:

Step 1: Log in as an administrator in your PC

 log in as an administrator.

Don’t forget to make sure you log in as administrator.

Step 2: Open “msconfig”

open msconfig.

In the search box on the taskbar, type “msconfig, then click on “System Configuration” to open the tool.

Solution 3: Repair Corrupted System Files with the SFC Command
