Method 5, check whether there is any abnormality in your boot startup items, because some startup items have bugs will also lead to the phenomenon of automatic startup after the computer is shut down, you can use the system optimization function of Kingsoft Guard pants, it will automatically help you analyze which programs are not necessary to boot up.

Cause: It may be caused by hardware problems, such as unstable memory heat dissipation, loose graphics card, network card, etc.

1) Press F8 immediately after booting to the advanced option appears 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 (if the reinstallation is also the case, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, and uninstall all the inappropriate things before the accident, or restore the system or reinstall it).

First soft and then hard, such problems are 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 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.

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

It's really not possible to reinstall the system, if you can't reinstall it yourself, go to the maintenance there to find a maintenance person to help you, it should take a little to spend it, if you can't turn on the machine by any method, this is a sudden shutdown, caused by disk damage, one is to deduct the motherboard battery and put it down, one is to put it for a period of time in the boot to try, or you can't repair it.

2) If this is always the case, first soft and then hard, once buried and reinstalled the system of the operator's late code, do not install software, patches, drivers, etc., to see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, don't install anything that doesn't fit (if you have any questions, please ask me).

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.

3) 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.

Poor contact, clean thoroughly.

Check all sockets and reseat the memory.

Reasons and solutions for computer not turning on:

Step 1: If the power supply does not respond, then check whether there is a problem with the power supply, poor contact, hardware, etc., and go to the second step, if it is unable to enter the system, it may be an operating system or software problem to go to the third step.

Step 2: Check whether there is a power supply problem, first see if the power supply is not plugged in well or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or go to a computer repair shop or sales store to find the same model of power supply to try it.

After replugging the power supply, press the power button again, and if it still can't be turned on, then press it for a while. If you change someone else's power supply to turn on, it means that there is a problem with the power supply, if it proves that the power supply is fine, it may be the hardware reason, go to the fifth step.

Step 3: Go to the last correct configuration to adjust, turn on and press and hold F8, enter the advanced options page, select "The most recent correct configuration", and press Enter. If it can enter the system, it may be caused by viruses, incompatible hardware drivers with the system, or operating systems.

After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, restart it after removing the driver, if there is still a problem, then go to the next step.

Step 4: Repair and install or reinstall the system, set "Optical Drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to perform "Repair and Installation". If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

Step 5: Check whether there is a hardware problem, disassemble the notebook to see if the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to sound that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it can't be started at this time, it is best to send it for repair, and the professional will check whether there is a problem with the hardware one by one.

Change the memory slot, remember to plug it in firmly, and try a few more times.

Dirty stuff stuck to the memory or memory slot.

There may be areas of poor contact.
