As soon as the computer is turned on, it doesn t work to restart several times, what s going on, how

Reasons for the automatic restart of the computer:

1. If the application software or running program software before the restart occurs, it may be a restart caused by the program software, uninstall the program software and reinstall it, if the failure is still there, it means that the system has an error.

2. Press F8 to enter the safe mode and then exit, and then enter the normal mode. You can also use the system restore function that comes with the system, and if you reboot troubleshooting, it is a reboot caused by damaged system files.

3. Check the motherboard, the motherboard aging, capacitor failure or bursting, the motherboard and the chassis backplane short-circuit, etc. can cause a restart, you can take the motherboard out of the chassis to check or test, and then check whether the bottom of the CPU fan heatsink silicone is dry, if it is dry, clean the silicone on the CPU fan, and then re-coat the good silicone. Then check whether the CPU fan is turning and whether the CPU temperature is normal.

4. If the fault is still there, then check the power supply, the power supply quality is poor, aging or the power is too small, can not meet the power supply needs of the computer accessories, you can replace the high-power and high-quality power supply, if the troubleshooting is the power supply caused by the restart failure.

The computer can't turn on and automatically restarts the solution:

1. Poor computer heat dissipation can easily cause the computer to automatically restart, because the CPU has a self-protection function, when the heat threatens the computer hardware, it will shut down and automatically protect, if this is the case, it is recommended to place the computer in a dry and cool place, and ensure that the fan runs normally to ensure that the computer has good heat dissipation.

2. Secondly, there may be problems with computer software, including computer poisoning, and software conflicts or errors. These may make the computer restart automatically, if you want to rule out software problems, you can first kill the virus and then reduce the software running in the computer, tentatively run the software to see under what circumstances the computer automatically restarts, if you find the software that caused the restart, you can take a look at it, if you are not sure, you can reinstall the system to try.

3. Computer reboot caused by other computer problems, including other computer hardware problems, such as hard disk bad sectors, etc., these problems should be tested by computer hardware test software. If there is a problem with the detection, you should go to the repair shop immediately to repair it.

The graphics card, or the screen is broken.

We often encounter various problems when using the computer, most of the problems can be solved by trying to restart, but some people find that their computer suddenly keeps restarting, resulting in the computer can not be turned on and off normally, can not be used normally, so why is this? Today, let's share the reasons and solutions for computer keeps restarting!

The solution is as follows:

1. There is a problem with the system.

If the system loses files and lacks some kind of critical registry information, it will restart constantly. In this case, we just need to reinstall the system.

2. The computer hard disk is damaged.

If there are bad sectors in the hard disk, water will also cause continuous restarting. At this time, we need to look at the damage of the hard disk to repair or replace.

3. The memory module is faulty.

If the memory module is not plugged in properly or the memory module is damaged, the computer will restart, and the memory module can only be replaced.

4. The power cord of the computer is damaged.

This phenomenon can also occur if the power cord is damaged, and this situation is the best way to solve it, and only need to replace the power cord.

Summary: The computer keeps restarting is probably the four reasons for system problems, computer hard disk damage, memory module failure, and computer power cord damage.

1. Check whether the socket has electricity, unplug the power cord, press the power button 5 to 10 times repeatedly, discharge static electricity, plug in the power cord and try to turn it on.

2. The computer power supply detection only needs to short-circuit the "green" and "black" two wires, and the green wire and ground of the "PS" and "on" ends of the power supply can be short-circuited.

3. If the power supply fan rotates, it means that the power supply is fine.

4. Unplug the "Power SW" switch cable on the motherboard, and use tweezers to short-circuit the "Power SW" switch.

5. Check whether it can be turned on, if it can be turned on normally, just replace the switch wire.

6. It can't be turned on yet, it may be caused by "memory", "graphics card", "CPU", "motherboard" and other devices, and the damaged equipment needs to be replaced.

Is it that the CPU fan is broken and overheated.

Reinstall the system and try it.

It is recommended to change to a new computer to solve all problems.

First, if the computer is restarted when the system is loaded, it means that the operating system is damaged, not a hardware problem, so you only need to reinstall the system or repair the system

1. Keep pressing F8 when you turn on the machine, and the safe mode will appear, as shown in the figure below

2. Use the up and down keys on the keyboard to move to the last correct configuration, and hit enter to enter the system

3. The computer is entering the system normally, otherwise you need to repair the disk bad sectors or reinstall the system.

4. If the above steps are invalid, you need to use a system CD to repair the system, provided that you have a system repair disk.

Second, if the computer is restarted during hardware detection, and the system has not been loaded, then it is basically a loop caused by the hardware to start, and the steps to eliminate the problem in hardware:

1. Poor heat dissipation. Due to the influence of weather temperature or the insufficient speed of the CPU fan, the system overheats, which will lead to the automatic shutdown and restart of the computer, it is recommended to check whether the system temperature is normal. 2. Memory reasons.

When the contact between the memory and the motherboard socket is loose, it may also cause the computer to automatically shut down and restart, it is recommended to check whether the memory is plugged in tightly with the motherboard. 3. Power supply problems. The insufficient power supply of the power supply is also an important factor that causes the computer to automatically shut down and restart, or the power supply is burned out internally, resulting in the failure to supply power normally.

4. Motherboard problems. If you use the computer for a long time, there is too much dust in the case, which causes the dust to adhere to the circuit of the motherboard and other boards, which may cause a short circuit and cause cyclic starting, so it is recommended to clean the dust in the case frequently.

5. The CMOS battery of the motherboard is dead. A dead CMOS battery on some motherboards can also cause a cycle to start, so it is recommended to replace it with a new one.

6. Remove the discrete graphics card, boot it to see if it can start normally, this step is mainly to verify whether there is a problem with the discrete graphics card, if the discrete graphics card is not installed, this step can be omitted.

7. The chip CPU is damaged. Whether the chip is damaged needs to be professionally tested by professional maintenance personnel, and if conditions permit, you can also replace it with a new one.

The solution to the infinite restart of the computer will not turn on:

1. If the signal light will still light up and the screen will light up after the computer presses the power button, then the computer is likely to have a problem with the software, and there is no problem with the hardware;

2. The software problem that can make the computer keep restarting may be that the computer is infected with a virus, or the system file is damaged, for the software problem, we can press the F8 key when booting, open the advanced options menu, and select "Last correct configuration";

3. If the methods mentioned above are not useful, then the simplest and crudest solution is to reinstall the system;

Let's see if there is a problem with the system, reinstall the system to see, if it doesn't work, it may be a problem with the BIOS, restore the factory settings, if it doesn't work, then it may be a hardware problem, and you need to get it for after-sales inspection and maintenance.

Check the power button and restart button on the host to see if it doesn't pop up after pressing it, if it doesn't pop up, use a toothpick to pick it out. It could also be a system failure that requires the system to be repaired or redone.

This situation is caused by your computer being poisoned, and as long as you reinstall your computer program again, your computer problem will be solved.

EnterSafe Mode (Power onKeep pressing F8).>Select".Configure it correctly for the last time!

As a novice computer who can only use the computer and cannot repair the computer, I don't know how to solve the problem when I encounter a computer problem. The computer itself is complex, and there is a good chance of problems. For example, it is not uncommon for people to encounter the problem that the computer will not turn on, and even repeated restarts will not solve the problem.

So is there any way to solve this problem? The following will introduce you to the specific solution that the Lenovo computer cannot be turned on after repeated restarts.

Method 1: Unplug the power supply and hold the power button for about 60s, and then try to turn it on after discharging.

Method 2: It may be that the BIOS battery is running out of power, if so, the BIOS battery needs to be replaced.

Method 3: Select the boot press F8 to the advanced option to appear in the release, and then we select the "latest correct configuration" Enter to repair, or make a PE boot disk, enter the system repair startup item, start with the boot disk, enter the PE system to uninstall the graphics card driver and restart the system.

Method 4: Force shutdown about 3-5 times Boot to check whether you can enter safe mode, if you can enter, uninstall the recently installed driver or software, and use antivirus software to optimize. If you cannot enter the safe mode, you can only back up your data, reinstall the system, or restore it with one click.

The above is the specific solution to the computer can not be turned on after repeated restarts, in general, it is still very simple and easy to use, I believe that through the introduction of the above content, you can easily learn how to operate, and smoothly restart the computer to resume normal use.

The computer can't be turned on after repeated restarts, see how the god solves it, you can also learn.

First of all, if the computer is restarted when the system is loaded.
