Blue screen of death

[mapuc]

Now it was my turn to get this famous Blue screen of death. I was away from the computer only web page open was subsim and FB

When I returned I saw a blue screen on my monitor-With a stopcode saying
0xc000021a I Rebooted three times before the computer started to collect info and restarted the computer.

Black screen then Running diagnostic-then a new message about repairing the disc which could take more than an hour

This toke around 20 minutes, then black screen again thereafter a new message-Reboot device or........(can't remember the rest of the message) I tried to restart the computer a few times, but the same messages popped up.

(This comment is send from my elder sisters computer)

I'd never heard of this BSOD before so I looked it up, there are a multitude of possible causes so you'll have to go through them one at a time, my guess is that you won't do that so expect some more of this BSOD in the future.

The Windows error code 0xc000021a, also known as STATUS_SYSTEM_PROCESS_TERMINATED, indicates that a critical system process like Winlogon or CSRSS has failed, causing the operating system to halt. This can lead to a Blue Screen of Death (BSOD) and prevent the computer from booting properly.

Possible Causes:

Corrupted system files: This is a common cause, especially after a failed Windows update or a corrupted hard drive.

Incompatible software: An incompatible third-party program can sometimes interfere with critical system processes.

Failed Windows upgrade: An incomplete or failed upgrade can leave the system in an unstable state.

Incomplete installation: If a software program was not installed correctly, it could lead to this error.

Backup issues: If a backup program did not correctly restore files, it could lead to mismatched system files.

Malware: In some cases, malware can also interfere with system processes.
Hardware problems: While less common, hardware issues like a failing hard drive can also cause this error.

Troubleshooting Steps:

Boot into Safe Mode: Try booting into Safe Mode to see if the issue persists. If it doesn't, it suggests that a third-party application or driver might be causing the problem.

Run System File Checker (SFC): This tool can scan for and repair corrupted system files.

Update drivers: Make sure your drivers are up-to-date, especially graphics drivers, as they can sometimes cause issues.

Run Windows Defender Antivirus scan: Scan your system for malware, as it could be interfering with system processes.

Check disk errors: Use CHKDSK to check for errors on your hard drive.
Uninstall conflicting software: If you recently installed a new program, try uninstalling it to see if that resolves the issue.

Perform a System Restore: If you have a recent system restore point, restore your system to that point.

Reinstall Windows: If all else fails, you may need to reinstall Windows.

Consider using DISM: The Deployment Image Servicing and Management tool can be used to repair the Windows image.

Use the bcdedit command: This command can help rebuild the Boot Configuration Data (BCD), which is used by the bootloader.

Thank you. Maybe it is the hdd who iis damaged-'cause that's what it says 'repairing hdd(disc)'

Under all circumstances I'm taking it to a computer service company to see if it can be repaired or not.

I hope it can be repaired, since I have three pdf-files on my desktop which are important. Yes I should have copied them and saved them on a USB. But who would have thought I would run into such a computer breakdown.

I haven't installed any hardware since I bought the computer and I haven't installed any software the last couple of years. Only upgraded them when needed.

If everything else fails and you end up with a new system or a newly installed fresh HD in the old one, you can keep the old HD externally and later attach it to the freshly installed system, trying to extract those PDFs. I would do so only if it is verfified fact that the HD had a technical problem and no software-induced one: malware in other words, else you would just infest your new system with the old problem. If software or "unknown cause" is the problem, never attach the old HD to a new system again.

Thank you Skybird - I'll ask the service person if this can be done or not and what they else can do to save these pdf-files.

I'm fully prepared on the fact they will say it can't be repaired-Remember it is their main task to sell me a new computer-They will therefore say: Sorry it can't be repaired

I have to sooner or later make a change of operations system-from WIN10 to WIN11. Before that I have to save some important files on my computer mostly these pdf-files.

I deliver my computer yesterday and the repair man said, it's mostly a hardware failure when you get this kind of stopcode.

Today I got a call-The HDD is kaput-He will try to save as much he can, especially these pdf-files.

Ach so ein......

Now it gonna going to be interesting to see how much a new ssd harddisk cost and if I can get win11.
