The motherboard is faulty. It is recommended to upgrade to the latest version of BIOS first. If the problem still cannot be solved, the only option is to send it for repair.
If the fan can start, it means there is no problem with the power supply, but if it does not self-check, it should be a problem with the motherboard. Since the self-test has not been entered, of course there is no way to redo the system. The problem with the motherboard is relatively big. You can first check whether your motherboard has expired and then go to a dealer, computer hospital, or technology market for motherboard testing.
Under the operating system, if the power cannot be cut off after shutting down or the power outage lasts very long, gradually remove the peripherals, minimize the test, only keep the CPU memory to start the hard disk, keyboard and mouse connection, remove other peripherals, try Can the power be turned off quickly and normally after shutting down?
1. After the computer is shut down, part of the computer's power supply is still working, the standby power supply still provides part of the voltage, and some of the indicator lights are also glowing at night. It is best to unplug the power supply to completely cut off the power. The voltage in the middle of the night is high and the standby power supply is easily damaged. Complete power outage saves energy and is safe.
2. After shutting down, the power supply only has 5v output of 5vsb, and the main output 5v and 12v are both out of power. Judging from the description of the problem, it should not be a fault. The fan light is designed in this way to indicate the standby state. .
3. Turning off the ASUS motherboard RGB light after shutting down can be set in the BIOS. After entering the BIOS--Advanced--RGB LED lighting---in sleep option select " Close" and save the BIOS settings.
4. This is a fault of the power supply or motherboard, which cannot be solved by reinstalling the system. You should try changing the power supply first (borrow one, buy it if you are sure it is a power supply problem). If the problem is not solved, it must be a motherboard problem. Go replace or repair the motherboard.
5. Normal. The questioner wants to ask, after the Gigabyte motherboard is shut down, the fan will not stop, but will continue to spin for a while and then stop. Is the answer yes? Some motherboards have an automatic cooling function. After turning off the main power, if the CPU temperature is too high, the fan will continue to spin for a while to lower the temperature and then stop.
1. The motherboard BIOS setting error usually occurs when the CPU radiator fan is still spinning after the computer is shut down. Most of them are Caused by incorrect motherboard BIOS settings.
2. Normal. The questioner wants to ask, after the Gigabyte motherboard is shut down, the fan will not stop, but will continue to spin for a while and then stop. Is the answer yes?

After turning off the main power, if the CPU temperature is too high, the fan will continue to spin for a while to lower the temperature and then stop.
3. Load the BIOS default settings, then turn on the computer and enter the BIOS settings, lightly press the chassis switch. If this is a normal power outage, it means there is no problem with the basic hardware.
4. The CPU fan will not spin after the computer is shut down. It may be that the monitor is turned off or the graphics card is stopped, but there are still programs running in the memory and hard disk, so the CPU fan is still spinning.
1. Taking the computer Windows 10 as an example, the fan is still running after the computer is shut down. It may be because the fan is faulty or there is something wrong with the computer settings.

2. The motherboard BIOS setting is incorrect. Generally, the problem that the CPU radiator fan is still spinning after the computer is shut down is mostly caused by the motherboard BIOS setting being incorrect.
3. There are two main reasons why the cooling fan is still running after shutting down: The computer's advanced power management support is not turned on. If this is the case, click Start, Settings, Control Panel, and Power in sequence. Options, High-Energy Power Management, and then check Enable advanced power management support.
4. First of all, although there may be many reasons, based on personal experience, there is a high possibility that there is a problem with the power supply or motherboard or cpu fan pins and plugs.
5. The reason may be that the notebook has a lot of waste heat, so it needs to be cooled down when the computer is shut down. This can be solved by installing a radiator under the notebook. The reason may be caused by incorrect BIOS settings on the notebook motherboard, which can be solved by entering the panel and clicking on the power option.
This phenomenon indicates that the motherboard or power supply is faulty. The reason is analyzed as follows. : After the computer is shut down, only the 5VSB standby unit circuit in the power supply is still working, and its 12V, 5V, and 3V groups will disappear when the main conversion circuit of the power supply is turned off.
Just press the power button to shut down (if the computer is left on for too long, my experience is that it is better to restart the computer every once in a while to release the cache and continue playing).
The computer's advanced power management support is not turned on. If this is the case, then click "Start" → "Settings" → "Control Panel" → "Power Options" → "High-Energy Power Management", and then check Just "Enable advanced power management support".
Take the Windows 10 computer as an example. The fan is still running after the computer is shut down.

In short, it is normal for the fan to continue to run for a few minutes after the computer host is shut down, and usually does not affect the computer.
There are two main reasons why the cooling fan is still running after shutting down: The computer's advanced power management support is not turned on. If this is the case, then click Start, Settings, Control Panel, Power Options, High-energy power management, and then check Enable advanced power management support.
The CPU fan is still spinning after shutting down (Start → Shut down the computer → Shut down, the monitor is turned off, but the host power indicator is still on and the fan is still spinning).
