2. If it is hardware, it is generally memory, unplug the memory, wipe the gold finger on the memory, and then install it and try again.

4. If the above two points do not work, it is recommended to redo the system.

Hardware and software can be problematic Hardware problems include, for example, if you have a bad brand installed on your computer, Bluetooth, or a camera, a network card, etc., and there is a blue screen. The software has the drivers on the computer that are all on the original CD, and what is said is right, that there is a virus to destroy it for you (Stalker virus), my computer is infected with this virus, and there is no way but to redo the system, you can check it yourself.

Faults at the beginning of C, the error it reports is very evil, and it reports an unknown hardware failure, but most of the ** that starts with C has nothing to do with hardware. Basically, some drivers are started at the same time as the system!Or the problem of service,For example,Once I changed the F disk of a notebook to an E disk,The result is that this kind of C starts with **,Finally, I found that plugging in a U disk can start normally,Because there is an F disk in the system when plugged in,Then I found a hidden file,It was written by the system when it was turned on。

I unplugged this U disk and this problem appeared again.,Later, the E disk was changed back to F, and there was no problem.,Think about what is the software that starts with the system and leaves some files on the F disk.,Without it, it will be built by itself.,But there's not even a f disk.,It's all wrong.,So you can see this kind of blue screen compared to the above solutions.。 (xyz5819 original reply, welcome to copy).

Error name 0xc000021a: status system process terminated (xyz5819 original reply, welcome to copy).

Failure Analysis 0xc000021a error indicates that there is a corruption in a user-mode subsystem, such as Winlogon or the guest server runtime subsystem (CSRSS). This error is usually caused by corrupted or missing Windows system files, or the Windows installation folder is set with the wrong access permissions, etc.

If you encounter 0xc000021a error, we recommend that you try to start Windows with the Last Correct Configuration;If the problem persists, please reinstall Windows. In addition, some buggy security protection software may use Windows system files as malicious programs to detect and kill, which will cause Windows system files to be deleted by mistake and 0xc000021a errors occur when starting Windows. For example, in May 2007, Norton Antivirus misidentified the system files of the Chinese version of Windows XP with the MS06 070 update installed as viruses and quarantined them, causing a 0xc000021a error when Windows XP started and Windows XP could not complete the boot.

The correct system files have been manually restored before the problem can be resolved. (xyz5819 original reply, welcome to copy).

0xc000021a: status system process terminated (xyz5819 original reply, welcome to copy).

Error analysis: User-mode subsystems, such as Winlogon or Customer Service Runtime (CSRSS), are corrupted and can no longer be secured, causing the system to fail to boot. Sometimes, when a system administrator mistakenly modifies a user's account permissions, they are unable to access system files and folders.

This is a real-world hardware error.

Solution 1: Plug and unplug the memory module.

2 Hard disk data cable unplugged and plugged in again, most of them are the above 2 kinds, it really doesn't work is a system problem and it is difficult to reinstall.

Hardware errors. See if the CPU or graphics card is too hot, if the temperature is too high, clean up the dust and reapply the silicone grease.
