How to turn off the computer boot failure, about the computer boot failure

If the computer is turned on and fails, you can use a forced shutdown.

Press and hold the power button for more than 5 seconds to power off.

If there is a restart button, you can press the restart button directly.

Unplug the power supply and force it to shut down (risky).

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

Press and hold the power button for more than 5 seconds and the computer will shut down.

You check it like this:

1.Connect the VGA cable of the monitor to the graphics card and plug it in again, and both ends must be plugged in. See how. It's not good to connect the computer to another monitor to see if there is a problem with the monitor.

2.If 1 doesn't work, disassemble the case, unplug the graphics card and the power supply of the graphics card, blow the dust off the graphics card slot with a blower or a clean pump, and then wipe the gold finger of the graphics card with a clean eraser to clean it. Plug in the graphics card and power the graphics card, and try it back on.

The memory can also be cleaned in this way.

If it's not done, it may be a software problem.,Maybe your screen refresh rate is set high.,But it can't show that you can't change it.,You can only reinstall the system.,And then use the driver wizard to reinstall the graphics card driver.。

4.Look at the motherboard capacitor and inductor to see if there is any deformation and discoloration, and then see if the handwriting on the chip is burned. You try to press the start button and reset button repeatedly, a few more times, turn off the power and then connect it, and then press, if it can start, it is a motherboard problem, reset the line failure, only send it for repair.

There are many possibilities, as follows:

1. If you boot up the blue screen, the maximum amount of memory you can do is that the memory module is broken. (It is recommended that you get a good memory module to replace your previous one).

2. If it is a discrete graphics card, remove your graphics card and use an eraser to wipe the metal contact points, then clean the eraser residue on the metal points, and then use the same method as above to dispose of the memory module. (Note: Before removing the graphics card or memory module, if you don't have anti-static gloves, touch some metal with both hands to counteract static electricity and prevent static electricity from shorting some hardware on the circuit board).

3. The speaker is on the side of the case, it does not need to be connected to the speaker, as long as you speaker the line is plugged into the speaker number socket of the motherboard, if your speaker is connected normally, there is no sound, the fan rotates normally after booting, and the screen is just a light on. There is no display at all, and the screen has been black, which is most likely a problem with the memory module and the display (provided that the graphics card of your computer is a separate display, not integrated.)

The screen is showing that there is no signal.

If so, it may be caused by too much dust on the memory, CPU, and hard disk in the host.

If you can get it, you can take it down and wipe it off.

There are many possibilities, it may be that the memory is not plugged in properly, or it may be the graphics card, do you have a case horn sound? Is there a sound of dripping? How many rings?

Clean up the dust in the case, unplug it and wipe off the gold finger under various excuses.

The most direct way, reinstall the XP SP3 system, my disc has, I want to give a QQ, why install XP SP3? ,Because the XP system compatibility is very good,Better than win7,The cause of the problem may be a problem with the computer system driver,Install this XP,The problem of the driver is solved,I bought it in the disc type,It's not piracy,I've tried。

If the memory is not plugged in properly, it may also be a problem with the graphics card, has your case horn sounded? It's the sound of dripping.

The monitor is turned on.,Why is the screen still black?,Is it black when you use it?,And then do you have to restart it to use it normally?,It is recommended that you add mine.,I'll help you take a look.。

Is the screen's etc on or flickering?

There are many possibilities for this:

1. If the CPU temperature is too high (this is very common), it is generally dust that causes the fan not to rotate, and the CPU heat dissipation is poor, and the system protection will be automatically turned off.

2. The power supply is also possible, but if the general power supply is wrong, it will cause the machine to fail to turn on, and it will not go in and turn off automatically.

3. The system is infected with a virus.

4. If the motherboard has static electricity problems, it can be discharged.

Is there a motherboard alarm sound, such as "Drop! Or is it "dripping ——— continuous long beep? If there is, there is a problem with the motherboard, it is recommended to check the BIOS, if the BIOS can't enter, remove the battery on the motherboard, after discharging for 5 seconds, press back to the original position, clear the BIOS miswriting, try, of course, these are my experience with people, I don't know if I can help you.

It is estimated that the possibility of power failure is relatively high, so try to change the power supply.

Do you have two memory, it's an integrated graphics card, you try to insert one memory in different slots to see if it's a memory problem.

You have to tell what the problem is, and others will know how to help you solve it.

What's wrong, dear?

There are many reasons why a laptop automatically shuts down, such as a hardware failure of the motherboard, power module, or battery failure. You can remove the battery first to confirm whether it is related to the battery.

Another important reason is that there is a problem with the internal cooling system of the laptop, and the CPU temperature is too high, which will cause the automatic protection to shut down.

Auto Shutdown Troubleshooting Methods:

1. There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle discharge, and wait for 5 minutes to reverse install it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2. If the computer shuts down automatically when using a certain application software, the automatic shutdown failure may be caused by this program software, and the program software can be uninstalled.

3. Then check the power supply, the power supply quality is poor, aging or the power is too small, which can not meet the power supply needs of the computer accessories, and the high-power and high-quality power supply can be replaced.

4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5. Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing and inserting of different brands of memory and the CAS value setting is too low, etc., which can cause the computer to shut down automatically, and the memory parameters can be adjusted accordingly in the BIOS.

6. Check the motherboard, the motherboard aging, capacitor failure or pulp, the motherboard power pins, the motherboard and the chassis backplane short circuit can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and the CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then recoat the good silicone. If the fan is not normal, replace the CPU fan.

7. Cleaning method: It is a method to eliminate faults by cleaning the dust of the parts in the computer host. Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures.

For these faults caused by dust, it is generally more effective to use the cleaning method.

8. The power supply system is unstable, which can also cause the occurrence of automatic shutdown faults, and a UPS backup power supply with voltage stabilization function can be considered. ‍

Press and hold the power off button for more than 6 seconds, and the power will be automatically cut off and shut down.

Solution: Open the hungry slag hall machine and immediately press f8 to the advanced option to appear in the let go, select "the latest correct configuration" enter to repair, and press f8 to enter the safe mode to restore the system or reinstall the system.

First soft and then hard, such a problem is caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and look at the boot is still a problem? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If there is a hardware, take out the motherboard battery and put it on the charge, plug and unplug the memory under the beam bucket, clean the graphics card, check whether there is a problem with the hard disk, and if not, just overhaul it.

If this is always the case, first soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

In terms of hardware, such as whether there is a problem with the hard disk, memory, etc., whether the temperature of the CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.
