The computer can t enter the system when it is turned on, and the fan stops when it turns, like a re

In this case, it can be concluded that the hardware is broken, and most likely the power supply is broken.

First of all, because you see the self-test screen, but you can't enter the system, you can determine that your CPU and memory are not problematic, and if there is a problem with the hard disk, it will not cause the fan to stop and restart, and if there is a problem with the graphics card, don't say it, you can't see any picture at all.

In fact, the possibility of a problem with the motherboard is not nothing, but it is extremely small, I have encountered a lot of this situation, especially in the summer when the temperature is high and the power failure will be in favor of this situation.

Reason: The power supply is faulty, but it is not burned out, so it can barely run, when you turn on the machine, the power supply can also provide a certain stable current for the computer to start, but you are about to enter the system, the CPU operation increases, the power consumption of the whole platform increases, at this time the power supply can not provide enough stable current, so it leads to the fan you said to stop turning. In general, there is a problem with the capacitance of the power supply, or a problem with the transformer.

It is recommended that you have the conditions to find a good power supply to try it, if it returns to normal, you can completely conclude that it is a power supply, 99% of the power supply is a three-year warranty, individual high-end brands, like Kangshu's high-end series is a five-year warranty, if there is no warranty, you can take the power supply to the merchant for free warranty, do not disassemble the power supply yourself, that will lead to no warranty.

Hope the above can be helpful to you!

The solution to turn on the computer and the fan stops when it turns: 1. Pull out the memory module.

Use a dry cloth or eraser to wipe the gold finger of the memory.

Part; 2. Restore the BIOS settings to factory settings.

3. Clean up the dust of the computer; 4. Take the computer host to the computer store for testing.

The computer stops and turns again when the computer is turned on, and it can't be turned on repeatedly.

Fault analysis: The computer turns on and stops and then turns again, which is due to the computer hardware.

Caused by poor contact, short circuit of the motherboard or subsequent hardware, power failure, etc. The cause of these problems is not a good environment, humidity, and not turning on the machine for a long time.

1. The memory is loose or the gold finger is oxidized.

This is the most likely, and many users solve it this way. First of all, we will remove the memory, it is very simple to remove, press the buckles on both sides of the memory slot (there are also single-sided buckles) to pull out the memory module, we had better use a dry cloth or eraser to wipe the memory gold finger part, so as to avoid the problem caused by the oxidation of the gold finger, reinsert the memory into the memory slot, and try to boot it. If it doesn't work, you can try to change the slot and insert the memory, and in the case of multiple memory, keep one memory first and test it alternately.

If not, users with a discrete graphics card can also try to reseat the discrete graphics card.

Memory is re-inserted.

2. BIOS error.

Motherboard BIOS error failure can also cause this problem, we can try to factory reset the BIOS settings, we will have the motherboard on the coin cell battery.

Remove it, leave it for a few minutes, and then install the coin cell battery in place to restore the initial BIOS value. It is also very simple to remove the button battery, pull the buckle outward, and the button battery can be automatically ejected, and you can remove it directly.

BIOS settings are factory reset.

3. Caused by too much dust.

Dust is the biggest killer of hardware, cleaning up dust for the computer is a very necessary thing for us to maintain the computer in our daily life, dust accumulation is too much, increasing the temperature of the hardware, will affect the life of the hardware, many times, hardware damage is caused by too much dust. To clean up the dust, we can use a brush, a high-powered hair dryer, to remove the dust.

Clean up the dust. 4. Motherboard and power failure.

If the above method is tested or does not work, then it may be caused by the failure of the power supply or motherboard, this situation for the general population, there is no suitable hardware to replace the test, only to bring the computer host to the computer store for testing, let the store first replace a power supply to try, rule out whether it is a power supply problem, if the power supply is still the problem, and finally replace the motherboard to try. If the hardware is within the warranty scope, you can find after-sales, if not, you have to pay to replace the hardware out of your own pocket.

The above is the detailed content of why the computer turns on and the fan stops when it turns

My computer host can't start, the fan turned and stopped, what is the reason, such a situation, it may be a system problem, or it may be caused by too much dust in the fan in the case, clean up the dust first, and reinstall the system to solve it completely.

This is a hardware failure, it is recommended to check the failure of the motherboard and power supply, if it doesn't work, go to the after-sales service.

If the fan stops after one turn, the problem of the motherboard is relatively large, and it is recommended to replace the motherboard to check it.

There are many reasons but it's certainly not the fault of the fan.,Motherboard or power failure is more likely.,What you can do is to plug and unplug the memory graphics card and the like.,If you don't know in**, don't toss it and find a door-tos-door repair.。

It is recommended that you repair the computer, it may be that there is a problem with the fan or the motherboard.

I hope mine can help you, hope, thank you.

If you have this problem, it may be that the memory module is in poor contact, there may be a problem with the system, and there may be a problem with the power supply. Find a master to check it thoroughly.

In this case, there should be a problem with the power supply, you can replace a power supply to try.

There may be a problem with the power supply or fan, which can be checked with an alternative method or a multimeter to solve the problem.

It is estimated that the power supply is broken, so try a new one.

Hello, I'm happy to answer for you This is most likely a problem with the motherboard, which will cause the fan to stop when it turns on the machine.

2.If there is a problem in the boot circuit, it is most likely that the electrolytic capacitor in the COMS circuit or the boot circuit is bulging, and the leakage is leaking; 3.When the power is turned on, due to the lack of power supply, the fan can not be turned on when the power is turned on, and when the power is turned on to a certain level, the power of this capacitor is sufficient, and it can be turned on normally; 4.

It is recommended to replace the bulge on the motherboard, and the leaking electrolytic capacitor can be replaced.

The computer won't turn on, and the fan stops when it turns

Check whether the CPU and heatsink have been moved, the CPU is overheated, and the motherboard detects that the CPU is over-temperature and the CPU is shut down protectively.

The low speed of the CPU cooling fan will also overheat the CPU, and the motherboard will detect the CPU overtemperature and shut down the CPU protectively.

Check whether the power connector is loose, whether the fast fuse in the power supply is blown or the power cord is broken.

Usually the motherboard is faulty or the power supply itself is faulty.

This situation is usually due to a faulty motherboard (damage, short circuit, etc.) that causes the ATX power supply to protect itself and not work, or the power supply itself is faulty and does not work.

Recommendation: In this case, it is best to replace and test with a normal power supply.

I think it's very likely that the power supply is faulty, and there is a problem with the power supply, so the motherboard is only powered on after it is powered on, and then the fan does not rotate, so I think the biggest possibility is that there is a problem with the power supply.

If you encounter the problem that the fan stops and turns down, you should check the way the memory module is detected, unplug them one by one, and test the boot status. If it can be turned on and won't restart, it's a memory problem, if not, it's not memory. 2.

If the memory detection is okay, it still can't be turned on The CPU fan still stops and turns down, then check whether the host power supply is good, the detection method is the replacement method, test with other new power supplies, if it can be turned on, it will automatically restart, it is basically a problem with the power supply, no doubt. 3.If it still can't be solved, consider detecting the motherboard problem, which may be the motherboard's protection.

4.If it can be turned on, it will automatically restart,It's likely to be a system problem.,But generally this problem is relatively rare.,Generally appear on old computers.。 You can try to see if reinstalling the system can solve it.

Hello friends, judging from your description, it should be that there is a problem with the power supply, because the computer has been turned on, and the fan of the power supply has been turning, so the preliminary judgment is that there is a problem with the power supply, if you agree with my point of view, thank you.

The computer host cannot start, and the fan stops after a short period of operation, which is most likely caused by a hardware failure and fails the POST, while the fan runs immediately after powering on, so it will rotate for a short time.

There are many reasons, starting from the heat dissipation of the CPU, memory, graphics card, and motherboard chips may encounter faults, just check them one by one.

Hello! Judging from your description, it is a computer hardware failure, and the motherboard is more likely to fail, so it is recommended to send it for repair!

In this case, it may be that the CPU power supply part of the motherboard is damaged, or the CPU is damaged, and in rare cases, it may be a fault of the switching power supply. You can find a motherboard diagnostic card or go to a professional repair center to check and repair. Do not disassemble the machine by yourself, so as not to cause secondary damage.

Hello, there are many reasons for this kind of computer failure you mentioned, for example, it may be that the memory module is loose, or other ** connectors are loose, which will be caused.

This situation is usually caused by hardware problems, such as motherboards, memory, graphics cards, CPUs and power supplies. If there are conditions, it will be clear that they will be eliminated one by one.

Unplug the memory module first and wipe it, and then install it to see, if it still doesn't work, then unplug all that can be unplugged, try again, if it doesn't work, change the power supply, and finally change the motherboard.

Is the power fan down?

If the power supply fan stops, it should be that the power supply has been short-circuited and protected.

If the power supply fan is normal and the CPU fan does not rotate, it should be a problem with the motherboard.

Maintenance personnel also need to disassemble the machine for detection, replace the power supply, wipe the memory gold finger and other operations to analyze the fault.

The computer boot fan turns and stops, and it can't be started, it may be due to poor memory contact, power failure, and too much dust on the computer, and the solution is not the same, taking the poor contact of the memory module as an example, this ** is demonstrated by win10 computer, and the solution is as follows:

1. Dismantle the main engine.

Using a Phillips screwdriver, remove the screws on the back of the main unit. After pushing the cover of the main unit, the panel of the main unit can be removed.

2. Take down the memory module.

Locate your computer's memory module.

Hold both sides of the memory module outward with both hands at the same time, and the memory module can be easily taken down.

3. Clean the memory module socket.

Use a small, clean brush to clean the memory module socket. Then, using a drawing eraser, gently wipe the golden part of the memory module interface.

4. Replace the memory module in its original position.

Simply put the memory module back in place.

Computer boot to the problem of failure is a common event, computer maintenance experience we have encountered a lot of failures caused by the system can not be turned on, recently there are users to turn the fan to stop a bit, resulting in the computer can not start normally, ** after the system can not be used, what is going on? Through analysis, it is very likely that the CPU fan is not stable due to the power supply to the CPU, and of course, the problem of the motherboard cannot be ruled out. Let's take a look at the specific solutions.

1. First of all, we first eliminate the simple electricity, discharge the BIOS, you can remove the battery for a few minutes and then install it back, or you can directly short-circuit and clear the pins of the CMOS, and then test whether the fault exists.

2. Replug and unplug the power supply to the motherboard, mainly the main power supply and the finger or CPU power supply line. (At this time, you can also re-insert the memory)

3. Check whether the restart switch or power switch on the computer is sensitive;

4. If the above methods cannot eliminate the problem, it is recommended to replace the power supply.

Although the computer is only composed of a few kinds of hardware, but the degree of precision is very large, the above methods are only for most of the faults, if not solved, it is recommended to analyze how convenient.

The computer is now turned on, and the fan is turning and stopping, and it can't be turned on.

Hello, <>

There may be many reasons why the computer can't turn on the machine, and the following are some possible reasons and solutions:1CPU heatsink failure:

If the CPU cooler fails, the fan may turn for a while and then stop, causing the CPU to overheat and cause the computer to not boot. The solution is to replace the radiator. 2.

Power failure: If the power supply fails, the fan may turn for a while and then stop, causing the computer to not boot. The solution is to replace the power supply.

3.Trouble with memory failures: If the memory fails, your computer may not boot, or you may have a blue screen after startup.

The workaround is to replace the memory module. 4.Motherboard failure:

If the motherboard fails, the computer may not boot, or there may be various problems with the number of increments after booting. The solution is to replace the motherboard. 5.

Other hardware failures, such as hard disk failures, graphics card failures, etc., can cause the computer to fail to boot. The workaround is to replace the appropriate hardware.

If you are unsure of the specific cause, it is recommended that you contact a professional computer repair technician for diagnosis and repair. <>
