When the machine is turned on, the fan will automatically turn off the power immediately after 2s, a

This kind of alarm is generally an alarm sound of CPU overheating.

You can try to clear the CMOS first, because sometimes the CMOS has improper alarm and shutdown temperature settings that can cause this phenomenon.

If the CMOS cleaning does not work, it is a fan problem or the fan is not installed properly, try another fan.

Talk about the alarm sound in detail, if it is a short alarm, it may be that you have a slight short circuit on the motherboard, it is recommended to remove the card and reinsert it, all the cards, if it is a Gigabyte board, it may be that your memory is not plugged in well, from the time point of view, the memory is not plugged in the possibility.

Right! It's a hardware problem!

You have to know how the alarm is 0 directional. Then you can find out what the hardware is wrong.

For example, continuous long ringing is a memory or motherboard error, and the general memory is mostly the cause.

If it stops after 1 ring, it may be a graphics card.

It is recommended that you plug the hardware back in and remove the dust!

After pressing the power button on the front panel of the host computer to start the computer, the normal boot state is: first, the power is turned on and powered, and the system is self-tested and initialized under the control of the BIOS on the motherboard. If the power supply is working normally at this time, the power indicator on the chassis will be on. The sound of the mains fan turning can be heard; Hear a slight "swish" sound from the monitor (this is the sign that the signal from the display card is being delivered); The indicator light of the hard disk starts flashing (indicating that it is reading and writing); "num lockv" on the keyboard

Caps Lockw" and "Scroll Lock" lights on and then off. When the computer fails to start, the machine's live self-test program Posty will send an alarm from the PC horn.

It seems to be a hardware failure, because it is not on the scene, so I don't know the details, the simple point is that the hardware is loose, and the serious point is broken, no matter what, you have to take it to repair!

Haven't heard of it, has the system started? If it does, it's probably some spoof virus.

The power supply doesn't work, try changing the power supply of the case.

It's a very simple problem: there is a problem with CPU heat dissipation, and the middle of the heat sink and CPU should be reglued with silicone

If you look at your memory, it may be that the memory is not plugged in properly, you just take it off and plug it in.

The sound of the ambulance alarm should be a memory problem, use an eraser to erase the memory gold finger and try again.

You can short the power supply to see if the power fan will turn. It's the end of the 20-pin power supply, one black and one green near the middle snap position, connected to each other with tweezers or wire.

I want to say this situation, if the CPU turns on and there is an alarm sound, it is a memory problem, try to change the memory module, if the motherboard battery is dead, it will not light up the machine.

If the motherboard is faulty, it is recommended to send it for repair.

It is detected that there is a problem with the cooling of your CPU processor, and see if the CPU cooling fan is turning and whether it is not plugged in properly.

Fan rotation does not mean that it is normal, because the normal fan rotates very quickly, the socket is not in good contact, and the contact with the CPU is not in place, which will also lead to the failure to dissipate heat. If you can't see anything wrong with the fan and don't want to fix it, it is recommended to buy a new one.

It looks like there's something wrong with the CPU fan. You see the CPU fan plugs in the right no.

It's time for your computer to clean up the dust. Then there is the aging of the shaft of the fan. You remove the fan.

Switch to silicone. Silicone is a few bucks a tube. It is sold in computer stores.

Silicone aging is no longer heat dissipating. I drove it for a few minutes before. Temperature to 99

When it reaches 100 degrees, it will automatically shut down.

When the computer is turned on and booted, you can hear a variety of different "beeps" from the small speaker of the case, which is the information reported by the computer. The meaning of the "beep" sound is different for different kinds of BIOS.

The motherboard turns on without a fan, and the CPU heats up quickly and freezes.

Computer fan emergency repair, there is a sealing label on the fan, gently tear it off, you can see the fan hinge, go add a little oil, gently turn it by hand, and paste the sealing label. It is best to replace the fan.

The motherboard is aging as a whole, clean all the cooling units of the case (including the fan cleaning and refueling of the power supply) and the gold finger of the memory independent graphics card, and you can't turn on the screen yet, please tell me how long and short the alarm sound is. Good luck!

Ring** Graphics card fan CPU fan Power supply fan Generally speaking, the sound does not affect the performance of the system If you feel that the sound is not pleasant, you can change the fan alone The fan of the graphics card and CPU is easy to change and it is not worth much The power supply is not easy to get If it is an alarm sound that cannot be turned on, then it is not a fan problem.

Your power supply and graphics card have fans, you check it.

It may be that the CPU cooling fan is broken. If there is no fan that will burn out the CPU, please try replacing it with a fan.

It's because the POST test didn't pass, that's why there is that kind of sound. It should be overheating or something. It is recommended to fix it.

It may be that the fan of the CPU is broken, change it and try it, and it may also be the fan of the host power supply.

The alarm sound of the CPU temperature is too high, basically that kind of sound, if the fan is broken, the fan must be replaced, the current fans are with silicone, buy it back and replace it directly. If you don't change the fan, it will burn the CPU.

Long and short rings, how to sound, it may be a problem with other hardware.

The problem with the alarm sound of the ambulance should be on the CPU, go to the BIOS to see if the CPU has set the alarm, or if the CPU fan is not connected correctly. Try restoring the BIOS to factory settings.

The problem of contact between the CPU and the motherboard, generally the CPU socket is desoldered, which is the problem ,.. the motherboard80% repair rate,

It's either memory, or a fan, or a graphics card, and then it's probably a problem with the motherboard.

The alarm is the motherboard, and it will alarm when there is a temperature that is too high or incompatible

Check if the memory module is broken.

Try it on a different computer.

There is also whether the display is working or not.

The second is to check the hard disk, power supply, and motherboard one by one (these generally do not cause any problems).

The main thing is to check the memory module.

How long do your memory modules last?

And the graphics card is well checked.

Try to change the slot of the memory module, be sure to clean the gold finger, be sure to use alcohol, and pay attention to ESD protection.

If you're the motherboard of the AWARD, it's a power problem.,If it's the motherboard of the AMI, then count how many sounds it rings in total (according to your situation, it should be the AWARD motherboard.,Because the alarm sound of the motherboard of the AMI will stop),Then come to the space to tell me (I can't add the answer on the phone),I will give you a detailed answer.。 If it's a memory module problem, it should be like an air defense alarm for the award motherboard. ps:

You're a desktop, right?

Take a look at the motherboard fan, or turn the power fan on and add some lube near the shaft.

If it is a continuous alarm, it should be a problem with the memory module, and it is recommended to replace it with a new one!

First: The CPU temperature is too high alarm set in the CMOS, you can enter the CMOS to set it.

Second: If the CPU fan or system fan speed is too low alarm is set in the CMOS, it can also be solved by resetting the CMOS.

Third: When updating the hardware, the CPU fan is damaged or the fan is stuck by something, causing the CPU temperature to be higher than normal and causing an alarm, you can try to replace the fan to solve the problem.

It should be the alarm sound of the temperature. It is recommended that you check if the CPU fan and graphics card fan are working properly. It is recommended to remove the dust, if it doesn't work, change the fan and try it.

It's good to cool it down with cold water while playing.

Boot up: Press and hold the Del key into the CMOS, and then set the CPU Warning Tempreture to the high point in the PC Health options. 80 degrees average.

You should not use transparent glue, you should use white gauze, and put an alcohol cotton ball after work.

I've already said it myself. Also to explain.

That screw is loose, check it

Haven't had this issue.

Can't help you.
