Why does the computer automatically shut down before it finishes booting?

1. The brain card and the situation that the operation is slow or cannot be shut down normally or the shutdown is slow, or the virtual memory is small.

Here are some things you can do to speed up your PC as well.

Enter msconfig in the start menu run, remove all (except ctfmon) checkmarks in the startup and try to save and restart (you can speed up the startup), generally you start the run too much, or file conflicts.

Install 360 security guard, boot has been pressing F8 to enter the safe mode to kill, now nine out of ten poisons on the Internet are Trojans, so the anti-virus software can not find the virus, it is recommended to install 360 to check and kill;

2. Crash, generally because there is too much running software, or the computer is not well dissipated, too hot, replacing the CPU fan, or the memory is not compatible.

Enter msconfig in the start menu run, remove all (except ctfmon) checkmarks in the startup and try to save and restart (you can speed up the startup), generally you start the run too much, or file conflicts.

Install 360 security guard, boot has been pressing F8 to enter the safe mode to kill, now nine out of ten poisons on the Internet are Trojans, so the anti-virus software can not find the virus, it is recommended to install 360 to check and kill;

If the heat dissipation is not good, reinstall the CPU heatsink and graphics card fan, you can have poor contact, and the CPU fan can be replaced.

Replace the memory; 3. The black screen in the middle of the computer boot is generally missing system files, or graphics card drivers or viruses.

Press F8 to enter safe mode when booting up, remove the graphics card driver, reboot, and reinstall the graphics card driver.

Or enter the safe mode start menu, run msconfig enter, remove all (except ctfmon) checkmarks in the startup and try to save and reboot (this can also speed up the boot of the computer).

Reinstall the system.

Operating system (OS) is a computer program that manages and controls computer hardware and software resources, and is the most basic system software that runs directly on "bare metal", and any other software must be supported by the operating system to run.

The operating system is the interface between the user and the computer, as well as the interface between the computer hardware and other software. The functions of the operating system include managing the hardware, software and data resources of the computer system, controlling the operation of programs, improving the human-computer interface, providing support for other application software, maximizing the use of all resources of the computer system, providing various forms of user interface, enabling users to have a good working environment, and providing necessary services and corresponding interfaces for the development of other software. In fact, the user does not have to touch the operating system, which manages the computer hardware resources and allocates resources according to the resource requests of the application, such as:

Divide CPU time, open up memory space, call printers, etc.

Hardware reasons: It may be that the parts in the computer are not in good contact, or there is a heat dissipation problem. Solution, reinsert the memory, etc., and check whether the fans of the CPU, power supply, graphics card, etc. are normal.

I hope it can help you and I wish you a happy life!

It should be that the system files are lost, and it is OK to reinstall the system.

Clean up the memory and plug it back in. If it doesn't work, reinstall the system.

You can go to the after-sales service, go to change a system, it's free, and then you can check your battery and look at the 、、、

Reason for automatic shutdown of the computer:

1.Poor heat dissipation, power failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts).

2.When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools, please click Fast**.

3.In the running software, there are some software with the option to shut down when the task is completed, and the user may not have noticed and turned these switches on.

These software are more common, such as Thunderbolt, Express, anti-virus software, BT**, **** and so on. In the software settings, there is an action that automatically shuts down after completing a certain task. But generally the default setting is off.

The purpose is to automatically shut down the computer when a task is completed when a task is running a more time-consuming operation.

4.Other hardware reasons.

The solution to the automatic shutdown of the computer:

1.First of all, check whether there is a problem with the hardware, focusing on the power supply of the motherboard, CPU fan, host power supply, and power socket.

2.Check if there are some applications that have enabled shutdown after the task is completed. This is evident from this. The feature is that before shutting down, there will always be a program that has been run, and a dialog box will generally pop up to remind you to shut down.

3.Resolve virus Trojans and repair system damaged files. With the latest version of Kingsoft Antivirus 2011, you can complete virus removal and system configuration repair at one time. "

Follow my method to solve the problem, and ask me if it doesn't work.

Check your motherboard battery first.

Or power on and take a look at the power-on.

Otherwise, the power supply is broken.
