As soon as the computer is turned on, it will be restarted for a while, and after 3 times, the main

CPU fan rotation does not mean that the heat dissipation is good, and sometimes the heat dissipation function of the fan is poor. If the fan is easy to stop, then this phenomenon should be a problem with CPU heat dissipation, and you had better clean up the CPU fan. If not, there's something wrong with the motherboard.

Whether the antivirus software is working or not.

Didi sound is the sound of the machine alarm. Disassemble the case and wipe it.,It's not good to redo the system.,There's a tick tick that the computer hasn't broken yet.。。 o(∩_o...

It could be that you have two antiviruses installed on your computer.

What's going on when the computer is in use? Urgent!!!

Yesterday the system was restored and turned off.,After getting up in the morning, I found that as soon as I turned on the machine, it began to sound non-stop,There is a function button in the main chassis,If you press it, it won't ring.,But as soon as you let go, it's been ringing.,It's been ringing since the morning.,Who knows what's going on?,Urgent!!

Rise in an instant. The sound of the computer host is due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, causing a black screen and a dripping sound.

1. You can turn off the power first, open the compartment, dial out the memory, and use the eraser to face the part of the gold finger (that is, the place where there is a copper sheet).

2. Rub it back and forth a few times, and then insert it back into the memory slot (or insert it back into another memory slot), and it's OK.

Extended information: Poor compatibility: plug the memory into other motherboards, stable and reliable operation for a long time; Plugging other memory into the faulty motherboard also runs reliably and stably, and there are no alarms.

But put the two together, and there is a "didi" alarm sound. Such failures can only be resolved by replacing the memory.

Inferior slots: Manifested as a "didi" alarm sound when replacing multiple brands of memory, occasionally a certain memory does not alarm, but it may alarm again after shutdown and restart.

This kind of fault mainly appears on the low-grade motherboard of two or three hundred yuan, the reason is that the motherboard is low, and the quality of the memory slots used is also poor, so it can only be solved by replacing the motherboard.

Chip failure: This kind of fault is relatively serious, and the host can find that there are error defects in the memory during the boot self-test, and cannot pass the self-test and send out a "didi" alarm sound to prompt the user to check the memory.

This kind of failure requires plugging the memory into another host and checking if there is the same "tick-tick" sound. If there is, it can be concluded that there is a memory problem; If not, it may fall under the first or every second reason above.

Memory alarms caused by other faults: This type of fault is not common, it may be a motherboard failure or CPU failure, which causes memory alarms, which can only be replaced one by one by elimination.

The sound of the computer host is due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, causing a black screen and a dripping sound.

1. You can turn off the power first, open the compartment, dial out the memory, and use the eraser to face the part of the gold finger (that is, the place where there is a copper sheet).

2. Rub it back and forth a few times, and then insert it back into the memory slot (or insert it back into another memory slot), and it's OK.

After the computer host is turned on, it has been ticking two repeated rings, generally speaking, this situation should be a system failure or a problem with the hard disk! You can have tips according to the boot situation, in this case, it is recommended that you can find a professional to check the system, after backup, reinstall the system, if there is a problem with the hard disk, it is best to repair it in time, so as not to damage the hard disk, the content can not be repaired!

According to what you said, it should be the internal hardware failure of the computer, the two sounds should be caused by the loose memory module without poor contact, turn off the computer, turn off the power, you can open the chassis, pull out the memory module to clean up the dust, if you find that there is more dust in the chassis, you should clean and clean it first, it is best to use a hair dryer to blow the dust inside, and then install the memory as it is, check the joint parts and then press it tightly, turn on the power, turn on, if not, if there are more than two memory, only one is left on it, Turn on the computer to see if it is normal, and then insert other memories one by one, and try one by one. There is also a look to see if the CPU fan is turning properly. Take your time and good luck with your careful observation.

Let's make a system with a USB flash drive, and it is estimated that it is enough to start and open.

PC restarts automatically? Please take a look at the content below, I hope it will help you.

1. If it is an automatic shutdown when it does not enter the system, it goes without saying that it must be a hardware problem. If the CPU is overheated, there may be problems with the memory, graphics card, power supply, and hard disk

Clean up all kinds of fans, and use an eraser to erase the gold finger of memory, graphics card, and hard disk.

Press it again to check the data cable and power cable. The fan can be blown clean with a hair dryer, and the dust paper on the center shaft of the fan is removed and a few drops of cooking oil are dropped.

It can also reduce noise and increase speed.

2. If the computer is shut down after entering the system, it is recommended to click F8 at startup, and click to enter the system with the last correct configuration, and try to solve it!

3. Open the hardware detection software, such as the host hardware and operating system benchmarking software

ultimate

to detect the CPU temperature.

and other important parameters, the general CPU temperature is too high, the computer will automatically shut down in order to protect itself, and check the power supply, it is not normal, the system does not want to work stably!

4. Then check it with software to see if there is a virus on the computer, such as turning on the automatic shutdown software, it is recommended to check and kill it all!

The chassis rings and the system can't get in.

Since you didn't say how it sounded, I can't tell directly.

Let me give you a reference.

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS setup and reset the incorrect option.

1 Long 1 Short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 Long 2 Short: Wrong monitor or graphics card.

1 Long 3 Short: Keyboard controller error. Check the motherboard.

1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated short rings: Power supply issues.

No sound, no display: Power issue.

Computer Chassis Tick Tick. The monitor can't be connected. It's the memory that's loose.

You can clean up the inside of the computer and plug it in.

1. If the system fails, use PE to see if you can enter the PE system, and if you can, you can eliminate the hardware failure.

2. The CPU fan does not dissipate heat well.

3. The power supply is unstable.

4. The capacitor of the motherboard is damaged.

Hardware problems can only be eliminated by replacing accessories!

I deleted 360 and there are still unintelligible ones! Then use PC Manager to kill the virus! It turned out to be like this when I was told to restart.

The main computer case keeps ringing is mainly because the hardware inside the host cannot pass the system alarm caused by the boot SELF-test.

There are many reasons why the hardware cannot pass the POST, and you can check it from time to time through the troubleshooting method.

First of all, check if the fan on the surface is working properly. Including CPU fans, power supply fans, and graphics card fans.

Check for loose hardware caused by poor contact. Reseat and install the memory modules, graphics cards, hard disks, and CPU fans.

Check the surface of the motherboard's capacitor for liquid spills or bumps.

When there is no problem with the above, it means that one of the hardware is damaged, and you can remove it one by one and replace it with another machine to try, and check which piece of hardware cannot be replaced one by one.

This is the host alarm! It seems that one by one is a hard disk business. Because you turned it off directly in the case of a crash.

Grass, it's no wonder that the hard drive isn't broken! It seems that your hard drive may have bad sectors and it is in the system disk. You're going to have to change your hard drive, it's going to be useless!

The laptop won't turn on, and it rings. Most of them are memory module issues. This problem can be solved after disassembly and cleaning.

Memory or motherboard. Try unplugging the memory module, wiping it clean, and then plugging it in and turning it on.

Let the professional computer repairer take a look, it's best not to fool around, if it's still under warranty, you can call them to see it for free.

That's not an important problem.,As long as it can be turned on.,That tick is to say that it can pass the self-test normally.,Successfully turned on.,Since it can be turned on.,It doesn't matter if it sounds or not.。

The answer is a normal phenomenon, and a short sound of "drop" when the computer is turned on means that the self-test is successful. POST refers to the behavior of a computer system, powered on, (BIOS program), including testing of the CPU, system motherboard, basic memory, extended memory, system ROM BIOS, etc. If an error is found, it will give the operator a hint or warning, which is the sound when the machine is turned on.

Ask an oh oh thank you.

Answer: Disk self-test appears when booting, the screen is generally displayed in white on a blue background, so you can tell if there is a problem with the computer from the difference in sound, and the specific sounds are as follows: Award BIOS1 short: the system starts normally.

2 Short: General error, please go to CMOS setup and reset the incorrect option. 1 long and 1 short:

There was an error with the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard. 1 long and 2 short:

Wrong monitor or display card. 1 Long 3 Short: Keyboard controller error.

Check the motherboard. 1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption.

Try a different block of flash ram. Constant ringing (long sound): The memory module is not plugged in tightly or damaged.

If it still doesn't work, you can only replace a memory module. Ringing: The power supply and monitor are not properly connected to the graphics card.

Check all the plugs. Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

You're welcome dear. Rest assured that it can be used normally.
