The computer is turned on at the disconnection point and then booted up normally 20

This problem of the landlord is a normal phenomenon,Now the motherboard is the implementation of BIOS temperature control,If he can't reach the specified temperature, his number of revolutions will not reach the specified number of revolutions,There will be a phenomenon of stopping for 2-3 seconds。 (I'm talking about CPU fans), if it's a fan of the motherboard chip or a fan of the graphics card, then there is a problem.

In addition, inter's 845 865 915 945 has this phenomenon, which is also normal.

This is obviously a phenomenon caused by voltage instability. In fact, this is a process to protect your machine's hardware from high and low voltages that can cause hardware breakdown.

It could be a problem with the voltage in your home, but it doesn't happen all the time. So the problem should be with your power supply. Replace a power supply bar. It is good for the stability of your own system and the life of your hardware.

The rotation of the fan is part of the computer's host self-test! I don't know which part of the fan you are talking about? However, the current fan (used on the computer) is generally temperature controlled, and when the ambient temperature does not reach the specified temperature, it is possible that the fan does not even rotate, which is also normal.

In addition to the fact that it never turns, there is also a lot of resistance when you flip it by hand (normally it turns with a light blow), and you can conclude that the fan is broken!

First see if the power supply of the display is really connected--- the indicator light of the display is on, if it is normal, plug the interface of the graphics card and the connection cable of the display again and confirm, if it still doesn't work, unplug the graphics card and wipe the gold finger, and then install it, so it should be normal.

At first, it was moved by the electric current, and the fan did not turn as soon as the power was turned on.

I also think it's time to change the power supply to a better one.

The specific steps to solve the To Interrupt Normal startup displayed on Lenovo computer are as follows:

1. First of all, this sentence means "the system fails to boot, please insert the system disk and press the car", which means that our computer system is normal, otherwise it will not feedback this sentence.

2. Then wait 5 to 6 minutes. If the system returns to normal, it means that there is a problem with the hard disk or fan area of our system and needs to be replaced or repaired.

3. If there is still no response after 5 to 6 minutes, let's remove the battery and try to install it again, because the motherboard may be in poor contact.

4. If there is still no response, press F12 in the BIOS, and in the boot options, change Quick to Diagnostic.

5. The problem of "interrupting normal startup" was solved by restarting the computer once.

There can be many reasons why a computer boots up intermittently, but the most common cause is a hardware or software failure. There are a few possible reasons that could be causing this issue:

First of all, this has Biga probably because your hard drive has failed. If your hard drive fails, then your computer may be behaving abnormally during the boot phase. You may hear a creaking sound from your hard drive, which indicates that your hard drive is no longer working properly.

At this point, you will need to replace the hard drive and reinstall the system.

Secondly, it is possible that your computer's memory has failed. If you're having trouble with your memory module, you might encounter an error message or a blue screen of death when your computer starts up. If you suspect that there is a problem with your memory, you need to do a memory test and replace it in time.

At the same time, it is possible that your computer may be infected with viruses or malware. If you have malware or viruses on your computer, they can interfere with your system and cause problems with the startup process. You can use anti-cryptovirus software or anti-malware software to solve the problem.

In addition, a power failure or loss of bootloader can also cause this problem. In this case, you need to check if the power supply is working and if the bootloader is corrupted or removed.

In short, if your computer has intermittent boot problems, you need to research the possible causes and follow the prevention and resolution methods to solve the problem once and for all. <>

First, it is recommended to check the power supply, or replace the power supply!

Second, you can test it with a different fan. If it's a problem with the fan itself, it's good to change the fan, if it's a problem with the interface with the motherboard, then the problem is big, but before you make sure that there is a problem with the motherboard interface, you must first confirm that the fan you used for testing is good.

The third is the motherboard problem, some boards are of poor quality, resulting in this kind of problem, or the board is aging.

Fourth, the fan shaft is aging, that is, it can't start normally, but it can be used with the help of external forces, which means that the fan is too worn, just change the fan.
