Infinite restart, shutdown as soon as you enter the system, what s going on

If the phone restarts automatically and the machine cannot be used normally, it may be a problem with the system or hardware of the phone, and it is recommended that you send the device to a Samsung service center for inspection.

If the phone can be used normally after restarting automatically, we recommend that you try the following methods:

1.Check whether the auto-restart function is set: Settings-Reset-Auto-Restart, after turning on, the phone will automatically restart the device at the set time (some machines support this function).

2.Try to update the system version of your phone (please back up the data in your device before upgrading).

4.If the phone battery is removable, it is recommended that you replace it with another original battery to rule out whether it is a battery problem.

If the problem persists after the above operations, please bring the purchase invoice, warranty card and machine to the Samsung service center for the help of the engineer.

If you can't enter the system page after turning on your Samsung phone, we recommend that you perform the following steps to troubleshoot and deal with it:

1.Please press and hold the power button and the down volume button at the same time for more than 7 seconds to restart the device;

2.If the problem persists after restarting the machine, it is recommended that you bring the purchase receipt, repair card, and machine to the Samsung service center for inspection.

Note: If the machine can be turned on normally after following step 1, it is recommended that you optimize your phone as follows:

1.Settings - About Phone - System Update - Update, check if there is a system update push, upgrade the phone to the latest version.

2.If the phone supports smart manager or memory manager, it is recommended to close the applications that do not need to run automatically (it is recommended to set the automatic start of instant messaging apps such as WeChat and QQ to "on").

Method steps.

1.If the boot detects the hardware and before entering the system, then it is necessary to check the hardware and BIOS problems.

2. Try to enter the BIOS to see if there is an abnormality in red font, and check whether the temperature and voltage are normal. If the CPU temperature is high, then you need to reinstall the heatsink, and if the motherboard temperature is high, you need to confirm whether it is the actual temperature or a false BIOS alarm, etc. Some new motherboards have self-test lights, you can try to check from the self-check lights.

3 (2) There is no abnormality under the BIOS, then you need to minimize the test, empty the BIOS, and see if there is still a reboot. If so, cross-test to find out which hardware or BIOS is the problem.

Method Step 2

1. If you start up and see that the system logo has been restarted wirelessly before entering the system, then it is related to several reasons, hard disk, data cable, hard disk interface, system, etc.

2 (1) After booting and selecting F5 or self-checking, press F8 to enter the safe mode to see if the safe mode can be entered normally, if the safe mode can be entered, the installed system can not enter, then it depends on whether there is anything changed or installed in the follow-up, change back if there is anything changed, uninstall the program first if there is a program installed, if the security mode can not enter or it is also an infinite restart, then it means that there is still a problem with the installed system;

3 (2) can consider another installation method or the installation of the CD or other system ios documents to install,Or you want to install win7 can try to change win10 installation to see if there is still a problem,If it has not been solved,Then consider the hardware problem。

4 (3) If it is SATA hardware, change a SATA interface or change a SATA data cable or SATA power supply to test; If you have other hard drives at hand, it's best to test them with a different one. If it is a hard disk with other interfaces, see if there are other interfaces on the motherboard that can be cross-tested, or this hard disk can be tested after installing the system on other computers to see if it can enter the system normally? But note that it can't be a hard drive on an old motherboard, preferably the same motherboard.

5 (4) When testing the system, because some board types will have relevant requirements for the installation of win7, if you can, try to use win10 to install when testing (some old motherboards do not support win10 live bar).

6 (5) The BIOS can be considered for updating, or the BIOS can be emptied

7 (6) have been operated above, after installing the system, it will restart indefinitely, cross-test the hardware, which hardware to replace This problem is this hardware problem, and if all the hardware is replaced, the motherboard problem will be considered.

Because there is a problem with the host, you only need to send the host to a repair shop for repair, and this problem can be completely changed.

The computer always restarts indefinitely when it is turned on, it may be that the CPU is overheating, there may be a problem with the power interface, and there may be a virus on the computer, so it is necessary to operate it according to the specific situation.

According to my own experience, there are several reasons why the computer always restarts indefinitely when it is turned on: the computer CPU is overheating, the power supply problem at home, the computer is a virus, and the computer memory module is loose.

The computer always restarts indefinitely when it is turned on, which is your computer, but it may be that it has not been used for a long time, or it may be that there is a problem with the computer's system, etc.

This should be caused by incompatibility between the system and other software, aging of the hard disk, loss or damage of the operating system, etc.

I can temporarily divide it into two categories: "automatic restart caused by software viruses" and "automatic restart caused by hardware damage".

In this Q&A, I will teach you a way to quickly determine the cause of the failure, you can calculate whether the computer is restarted after the system enters each time it is turned on, or it is restarted when the BIOS self-test is just started, so that you can determine whether it is a software or hardware failure, so I will describe in detail the methods and operation steps to solve this kind of problem
