2. If the power cannot be cut off or the power is off for a long time under the operating system, gradually remove the peripherals, minimize the test, and only keep the CPU memory.
3. If it still doesn't work, it is recommended to reinstall the operating system. Remember to install the pure version of the system in the U disk boot mode, not in the way of doing a ghost recovery under PE. After installing the basic system, try to power off and shut down without installing any drivers.
If it can be normal, then please install it in the order of chipset driver--- network card driver--- graphics card driver--- sound card driver--- other necessary drivers. If a driver is difficult to shut down or cannot be restarted after installation, pay attention to check it.
4. Sometimes the shutdown mechanism is not on, pay attention to cancel the quick start.
5. Pay attention to whether the windows update of the operating system is in progress when the computer is shut down, and the first shutdown and restart will be very slow during the update or after the update, which is normal.

Anonymous users2024-02-06Hello, according to the problem description you provided: this situation is most likely a problem with the motherboard power management module. After a graceful shutdown, the CPU fan should stop spinning, but if the power management module fails, it will not be able to correctly recognize the shutdown command, causing the CPU fan to continue to run.
This situation may lead to problems such as overheating and excessive power consumption of the computer, which will adversely affect the life of the hardware. Therefore, timely maintenance is very necessary. To solve this problem, you can do the following:
1.Check for unconnected power cords. Make sure all power connections are secure and error-free.
2.Check your power management settings. In the BIOS, you can find the power management options and confirm that the settings are answered correctly.
3.Replace the power management module. If neither of the above methods solves the problem, then you may eventually need to replace the power management module to resolve the issue.

Anonymous users2024-02-05How to solve the problem that the CPU fan is still turning after the computer is turned off
Recently, a user said that after his computer was shut down, there was a problem that the CPU fan was still turning, and after waiting for a while, the processor radiator fan did not stop, so what should I do if the CPU fan is still turning after the computer is turned off? Here's how to do it.
Manner. 1. The motherboard BIOS is set incorrectly.
Generally, the CPU cooler fan is still rotating after the computer is shut down, and most of them are caused by the wrong BIOS settings of the motherboard. After powering on, press the DEL key on the keyboard several times to enter the BIOS, find the ACPI option in the BIOS interface of the motherboard, select [EABLED] with the up and down buttons, press [F10] on the keyboard to save the BIOS settings, or find "Load Default Setup" to restore the default settings of the BIOS. However, due to the different brands of motherboard BIOS settings, here is a simple way to restore the motherboard BIOS to the default settings, we need to open the main chassis, remove the round button battery on the motherboard, and then install it back to restore the BIOS default settings.
After we find the button battery on the motherboard, we will move the button outward, then the button battery will automatically pop out, the button battery will be removed, and we will install it in place.
Manner. 2. Select the high-performance power option.
Take win7 system as an example, we click on the "Start Menu" in the lower left corner of the desktop, and then click on "Control Panel", after entering the control panel interface, modify the viewing method to "small icon", find and click "Power Options", as shown in the figure below.
In the interface of power options, we can click [High Performance], and click on it to automatically complete the saving.
3. Caused by registry errors.
First of all, we press the "win key + R key" key combination on the keyboard at the same time to bring up the |Run, enter the command: "as shown in the following image."
After entering the command, we will enter the "Local Group Policyr" interface, we click [Management Template] - [System] in turn, and double-click the [Do not turn off the system power after the system shutdown occurs] option, as shown in the figure below.
In the interface that does not turn off the power of the system after the WIN system shutdown occurs, we click "Disabled" and confirm.
Fourth, hardware problems.
The biggest possibility is caused by power supply problems, there is also the possibility of motherboard problems, of course, if it is really caused by hardware, this small shortcoming is not recommended to be replaced, unless there is a warranty, every time the power is off.
The above is the shared way to get the CPU cooler is still turning after the desktop computer is shut down, and now you know what to do if the CPU fan is still turning after the computer is shut down! Generally, most of them are caused by problems with the motherboard BIOS settings, and I have encountered an old GIGABYTE motherboard before, and the CPU cooler fan will tremble after shutting down, and finally the motherboard BIOS is done.
The idea is incorrect: 1, if you just want to make the CPU high, you can go to Celeron 4 40 yuan or so (second-hand). If you think it's still low, then most of the motherboards corresponding to the CPU at a higher point are SATA interfaces, and your hard disk can't be used at all, so your upgrade ideas are a bit inconsistent from this point of view. >>>More
CPU is two categories of Intel and AMD, with it depends on how much money you spend to match, for example, G41 Intel chipset is generally matched with E3400 or E5200 or so CPU, the so-called low-end board with low-end CPU, with high CPU performance can not be played, spend more than 2,000 to buy an i7 CPU with a motherboard of five or six hundred yuan is not good, right, the power of an airplane is not fast on the bicycle, and the brakes can't keep up! Moreover, if you want to match the graphics card, it is the same, a good graphics card must have a good motherboard, a good power supply, a good CPU, so that the sub-performance can come out, if you spend money to buy a motherboard with more than 400 with a graphics card of more than 800, it is not good, although it can be used, but the performance will not go up. Normally, you can buy a motherboard with almost the same *** graphics card, and that's it.
1. Test the display separately Method: In the case of shutdown, turn on the power button of the monitor separately to see if the display has a similar "no signal" prompt, if there is good, if there is not, there may be a problem with the display. >>>More
Now the mainstream CPUs are Inter's Core series CPUs, especially the Pentium E E5200 and Core E7200 and quad-core Q6600 graphics cards, which have the mainstream HD3850 and 9600GT GTX HD4850 ==
It mainly depends on the user's purpose and budget. First-line brands, such as ASUS, Gigabyte, MSI, etc., are generally used in servers, and home users and office users with sufficient funds are not considered, and second-line brands, such as Onda, Rainbow, Panzheng, Shuangmin, etc., are excellent in quality and after-sales service, and can be trusted; As for the CPU, now the mainstream ones are dual-core, triple-core, quad-core, the brand is nothing more than two, Intel and AMD, they each have their own advantages, servers generally use Intel's high-end products, office users generally use low-end products; Home users generally use AMD's mid-to-high-end products, because AMD's gaming performance is relatively good, and with a graphics card (personal needs), it forms a well-balanced, office-integrated home computer. This is the personal view of the person who installed the machine, as for how the customer requires, or let the customer choose, after all, we still respect the customer's vision.
