There are many reasons for system file loss, which are basically divided into the following categories:

1. Trojan virus infects and destroys system programs, causing system file loss.

2. Due to the uninstallation program, some software may share a file, but the file disappears after being uninstalled. This may also cause the system file to be lost and the system to appear.

3. The computer frequently restarts or shuts down abnormally. When the operating system ends abnormally, it will definitely cause serious damage to the system, which is also one of the reasons for the loss of system files.

What should I do if the computer just turns on and the screen goes black and it says that the dll is missing from your computer

Install the system. Teach you how to install the system using U disk:

After installing a PE system on the U disk, plug it into the computer. You can use the motherboard to drive the U disk to boot, and then use it as a system. It is mainly convenient and can be operated better.

In addition, I will teach you a good way to install the system. Buy a USB flash drive and follow the steps below to install the system yourself.

The following is the U disk installation process: Take Chinese cabbage as an example

Prepare an empty U disk with no files stored (it is recommended to use a U disk of 8G or above. Note: the U disk will be formatted when making the PE system). Download the Dabaicai U disk installation system software. If your computer is available, just Install the U disk into the PE system on your own computer. If it is not easy to use it on other machines to make the U disk of the 'Chinese Cabbage' PE installation software, you can start the installation, insert the U disk into the computer and start it.

The best thing to do after preparing the U disk is: When the computer is normal or when it goes to the PE desktop, back up important files on the computer (mainly: important files on the desktop and important files in My Documents, Copy it to the D drive.) Then start executing the following things:

1, first download the WIN7 or WIN10 image to the hard disk or make a GHO file in advance and save it in the U disk, then create a new GHO folder in the root directory of the disk other than the C disk or the U disk. Create a GHO folder in the root directory of drive D, and then use UltarISO or WinRAR to decompress the WIN7 image and release it into the GHO folder.

Note: Remember not to create a GHO folder in the C drive, otherwise the GHO file will be cleared during the installation process and the installation will fail.

2. Insert the bootable USB disk into the computer and then turn it on:

If it is a new UEFI BIOS, you can generally press F12 directly to enter the quick boot menu, select the U disk name in the menu, and then boot from the U disk.

If it is an old BIOS, you must press Del or F2 to enter the BIOS, and then find the First Boot Device or 1st Boot Device under the Advanced BIOS Features project, or Boot, or Startup, etc. After entering, put the USB-HDD or Set the U disk name as the first boot,

For specific methods, please refer to the motherboard manual, or search online.

After starting the U disk, enter the U disk PE interface and select "Run Windows PE (system installation)".

3. After entering the Dabaicai PE or Laomaotao PE desktop, select the desktop shortcut icon "WIN System Installer" and double-click to run it.

4. The NT6 quick installer pops up. The first thing you need to do is find the system files you downloaded and decompressed previously, so press the "Open" button.

5, a file selection box will open, find the GHO folder previously created on the D drive, then find its subfolder Sources, and then find the install.wim file under the Sources folder. This is the installation file. After selecting, click the "Open" button.

6, then select the installation partition, which usually defaults to C drive. If you need to install to another drive, you need to adjust it manually. If you are a novice, it is best not to adjust it, because the system partition must be the primary partition, and It has to be activated, so if you don't know this, it's best not to touch this.

7. Here, the last confirmation window before installation will pop up. Take a closer look. If you are sure that you have selected everything, you can click "OK" and the installation will begin.

8. At this time, the system files in GHO will be copied to the C drive. It will take some time to copy several G files. Please wait patiently.

9. After the copying is completed, the prompt "Please restart the computer to enter the installation phase" pops up. Click "Yes" and the computer will restart immediately. At this time, you can pull out the U disk. If it is UEFI BIOS, it will still be downloaded from the hard disk. To start, if it is an old BIOS, you must enter the BIOS and change booting from the USB disk to booting from the hard disk.

10. After restarting from the hard disk and entering the computer, the system installation will begin, such as configuring the start menu, registering components, etc. The entire installation process will take longer, so be sure to wait patiently. Please adopt it if it helps
