Critical_process_died csrss.exe is a Blue Screen of Death error, and since this error crashes your system every time it occurs, it is important to know how to repair it under recent Windows versions.

These accidents were related to memory corruption (probably caused by a driver). Correct these BSOD error problems before contacting Microsoft support.

To do so, please run these two tests to check your memory and find out which driver is causing the problem. Please start the verifier first. You don’t need to run memtest unless the verifier doesn’t find the cause or you want to.

  1. Driver verifier (For complete directions, see here).
  2. Memtest. (For more information on running memtest, click here).

BSOD Error 0xc000021A normally occurs when the Csrss.exe file is corrupted. Csrss.exe belongs to the Microsoft client or the Runtime Server Subsystem and can be corrupted for several reasons:

  • System files have been mapped incorrectly.
  • Incorrect device drivers have been installed.
  • Third-party software is missing files

Here Are Some Ways To Correct csrss.exe Error:

Method 1: Manual boot from Windows

To solve this problem, you must start Windows manually. In most instances, booting Windows in safe mode would no longer work. You should then start it using force drivers to disable the signature in the advanced boot options. To do this, follow these steps.

  1. Restart the PC from Windows by pressing and holding the Shift key and choosing Restart. If you cannot access the Restart option on Windows, you may need to boot from a bootable USB port on Windows.
  2. You access an options screen. Select Troubleshooting to access advanced tools.
  3. On the following screen, choose Advanced.
  4. On the subsequent screen, you will find a variety of options. All you need to do is press Start Settings.
  5. There are a handful of options to choose from on the Home screen. Press F7 named Disable driver signature enforcement.

Your PC restarts with the option you have chosen and you can then optimize your PC with several different options

Method 2: Disable Windows services

  1. Press Windows + R > type msconfig > press Enter (or click OK).
  2. Click on the Services tab
  3. Make sure Hide all Microsoft services is enabled.
  4. Click Disable All, and then click Apply.
  5. Click on the Start tab
  6. Click Open Task Manager
  7. Disable all items individually and close the Task Manager.
  8. Click OK to close the System Configuration window.

Restart your computer. If Windows 8.1 starts normally, it means that one of the starters or services was defective. Start activating the ones you think are correct and restart your computer. Finally, you should be able to find the offender and leave it or uninstall the program.

Method 3 : Repair Windows 8.1 system files

If you still cannot boot with Windows 8.1, you should use this method to check Windows 8.1 system files.

  1. Insert the Windows 8/8.1 installation DVD/USB or recovery disk.
  2. Restart your computer
  3. Click the Next button
  4. Click the Repair Computer link.
  5. Click Troubleshooting > Advanced Options > Command Prompt.
  6. At the command prompt, type sfc /scannow > and press Enter.

Method 5: Resetting Windows updates

Probably the most common way a blue screen error occurs when a user turns off a computer while applying updates. The user can force the computer off if it is not turned off because it is waiting for updates. This will allow you to cancel the Windows update that failed:

  1. Insert the Windows 8/8.1 installation DVD/USB or recovery disk.
  2. Restart your computer
  3. Click the Next button
  4. Click the Repair Computer link.
  5. Click Troubleshooting > Advanced Options > Command Prompt.
  6. At the command prompt, type dism.exe /image:C:\ /cleanup-image /revertpendingactions (where C is the system drive of your computer).
  7. Press Enter to execute the command and cancel the update.

Method 4: Resetting the computer BIOS

Many affected users have reported successful resetting of their computer BIOS. The BIOS of a computer can be reset for a few minutes by simply pulling the CMOS battery from the motherboard, while this trick does not work on laptops as their motherboards are not readily reachable. To reset your computer’s BIOS, you have to:

  1. Switch off the computer.
  2. Disconnect all power cables from the computer and ensure that the computer is disconnected from the power supply completely.
  3. Loosen the computer case.
  4. Find and take out the CMOS battery from the computer (located somewhere on the motherboard of the computer).
  5. Allow about 1 to 2 minutes.
  6. Change the battery when you have been waiting long enough.
  7. Reinstall the computer case.
  8. Start the computer and verify that it starts properly under Windows.

Method 7: Disconnect the SATA adapter holder for your SSD.

There are some users who have a tendency to use a SATA adapter cradle for their SSD, but very few users have reported that the SATA adapter cradle can be the cause of this error. When the SATA adapter holder was removed and the SSD was connected to the motherboard directly, the issue was solved completely.

Method 8: Turning off sleep mode

Not many users reported having corrected the csrss.exe error by turning off sleep mode. To achieve this, follow these steps:

  1. Press Windows + S and enter power. Choose Power Options from the menu.
  2. Find your current plan and select the Change plan settings option.
  3. Then select Change Advanced Power Settings.
  4. Go to the rest area and disable all options.
  5. When you are done, press Apply and OK to apply the modifications.
