Why does my computer have to be turned on several times before it can be turned on?

This should be a hardware failure.。。

What is the reason why the new computer host automatically restarts several times before it can be turned onHello dear, the reason for the automatic restart of the computer: 1. If the application software or running program software before the reboot occurs, it may be the restart caused by the program software, uninstall the program software and reinstall it, if the fault 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 not be turned on automatic restart solution: 1, the computer heat dissipation is not good 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 be shut down and automatically protected, 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 heat dissipation is good.

2. Secondly, there may be problems with the computer software, including computer poisoning, and the software has punch molds or errors. 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 will automatically restart, if you find the software that caused the restart, 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.

The temperature is too high.

2.The voltage wave bends violently.

3.Hard disk bad sectors.

4.Memory overheating or local corruption.

The output current is too low.

The most important feature of the hardware structure of a microcomputer is the bus structure. It divides signal lines into three broad categories and boils them down to date bus, address bus, and control bus. This is very suitable for the modular production of computer components, which promotes the popularization of microcomputers.

The chassis is the outer coat of the computer host, most of the components of the computer are fixed in the inside of the chassis, the chassis protects these components from collision, reduces dust adsorption, and reduces electromagnetic radiation interference.

The power supply is the power source of the main machine, and all components of the main computer need power to be powered, so the power quality directly affects the use of the computer. If the power quality is poor and the output is unstable, it will not only cause crashes, automatic restarts, etc., but also may burn components.

There are two possibilities: one is to see if your power supply has a capacitor drum? This can happen when the power supply is insufficient. The second is whether the capacitor of the motherboard is drum

The computer host is turned on and repeated many times because the computer itself is faulty, and the specific solutions are as follows:

1. Take off the BIOS battery on the motherboard, install it again after 30 seconds, readjust the time, and try again.

2. If the above does not work, try to plug and insert the memory module;

3. If it doesn't work, it is recommended to estimate the power supply problem, and it is recommended to try another one;

4. If it is not possible to change the power supply, if there is a problem with the motherboard, if there is a discrete graphics card on the motherboard, remove it and do not use it, or see if there is a capacitor bulge on the motherboard, if there is, repair or replace the motherboard;

5. If it doesn't work, there may be a problem with the hard disk, there are bad sectors, etc., and it is estimated that the hard disk will have to be replaced.

Hello friends, this is likely in two ways:

The first aspect is the problem of your power supply, when the filter capacitor in the power supply, or other capacitors bulge, leakage, there will be leakage, because you have just started, the capacitor in the leakage, so it causes the power supply not to have enough power supply to the host, so it will be restarted, when the power of this capacitor reaches the starting voltage, your computer will be able to start normally, which is why it has to be restarted many times to be normal.

The second aspect is that the memory and the memory socket are in poor contact, or the memory integration block is soldered, there will be repeated restarts, so Jianyi, the memory can be replaced with a memory slot, or a memory or the memory integration block is welded, and your problem is solved.

Try changing the graphics card to a different slot.

Flash a red light. It should be the hard disk indicator, and if it doesn't flash, it means that the hard disk is not found. or did not read the hard drive. I should also have experience in thinking about it from this aspect.
