1: Run a virus scan

The CRITICAL PROCESS DIED error could be caused by some spyware or malware. Even if they aren’t the dangerous kind, they could still cause the problem.

2: Update device drivers

In most cases, buggy drivers could cause Critical Process Died blue screen of death error. You can try updating all the device drivers to the latest versions to fix it. 

There are two ways you can get the right drivers for your video card and monitor: manually or automatically. 

Manual driver update – You can update your device drivers manually by going to the manufacturer’s website for both all your devices, and searching for the most recent correct driver for each. Be sure to choose only drivers that are compatible with your variant of Windows 10. 

Automatic driver update – If you don’t have the time, patience or computer skills to update your device drivers manually, you can, instead, do it automatically with  Driver EasyDriver Easy will automatically recognize your system and find the correct drivers for your exact hardware devices, and your variant of Windows 10, and it will download and install them correctly

3) Click the Update button next to any flagged device to automatically download and install the correct version of this driver (you can do this with the FREE version).

4: Run SFC & DISM

If your hard drive or RAM is corrupted, a blue screen of death error such as Critical Process Died would pop up and force reboot your computer. This is your computer’s way of protecting itself from further damage. You can run two built-in checks to make sure that your disk and RAM are at a good state: 

1: Run SFC (System File Checker)

SFC stands for system file checker. It helps you replace corrupted or faulty system files with new good ones. 

1) On your keyboard, press the Windows logo key, and type in cmd. Right-click Command Prompt and click Run as administrator

2) Type sfc /scannow and press Enter on your keyboard. 


Wait for a while for this process to finish. Then restart your computer. 

3) Restart your computer when the check is done. See if the Critical Process Died error happens again. If the problem continues, move on to the DISM check. 

2: Run DISM (Deployment Image Servicing and Management)

DISM stands for Deployment Image Servicing and Management. If the system file checker can’t help you fix the Critical Process Died blue screen of death error, you can run DISM as well. Otherwise, it wouldn’t be necessary. 

1) On your keyboard, press the Windows logo key, and type cmd. Right-click Command Prompt and click Run as administrator


2) In the Command Prompt window, type in the following commands one by one, and press Enter key after each one. 

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

3) Restart your computer when all the checking are done.
