The computer will automatically shut down after a long time5

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.

Graphics card, memory module, the important thing is these 2, you plug them in again, plug in tightly

The host overheated, and the alarm was called.

It may be that the hard drive is not good, you open the case, clean the dust on the fan, or remove the memory module and the display and plug it back in!!

There are several possible scenarios for a computer to freeze:

1. The newly added hardware equipment is not compatible with the old or loose or other incompatible hardware is inserted;

2. During the computer networking, the Trojan virus was infected and an incompatible driver was installed;

3. The hardware settings are overclocked;

Solution: 1. Check and replace incompatible hardware, or use the original accessories;

2. Select the system with the right hardware and reinstall it;

3. Re-set the normal operation frequency of the hardware.

According to the sound of Didi, focus on detecting whether the hardware is loose, and then follow the steps to detect in turn.

Is it that the CPU heat dissipation is not good, open the case cover and touch the hot hands?

The motherboard has an alarm, see if the CPU temperature is over 80, just change the fan.

The problem may be with the memory module, unplug it and clean it up.

When the computer starts, the motherboard buzzer keeps "ticking" and does not turn on, which is usually a memory failure.

The memory module is not a very easy part to damage in the computer, but it is a part with a relatively high failure rate, it is connected to the motherboard by the method of plugging, the reliability of the connection is relatively poor, and the memory is a high-speed device, once the contact is poor, there will be various failures. In this case, please try to remove the memory module, gently wipe the gold finger (contact) of the memory with a stationery eraser, wipe off the dirt on the surface and reinstall the test, which can generally solve the problem. If this method doesn't work, try replacing the memory module.

In addition to memory failures, graphics card failures, CMOS failures, etc. can also cause the motherboard buzzer to alarm all the time but fail to boot, but it is relatively rare compared to memory failures. If necessary, diagnostic cards can be used to determine the source of the fault.

Continuous short-tone supply voltage issues. The voltage is too high. 2.

The sound of an ambulance is accompanied by a long start-up sound, the CPU is overheating, and the CPU fan is not installed or is not installed in place. 3."Tick.

's continuous, spaced long tones. Unable to detect memory (loose memory, poor contact with dust on memory gold finger, memory not inserted, memory corruption) 4“.

"Didi" - a long and short continuous beep of the graphics card alarm (graphics card damage, loose graphics card, poor contact of the graphics card gold finger dust, failure of the power supply part of the motherboard graphics card) If there is only one short beep or no self-test passes. It's normal. Judge by the sound of your own boot.

Look at the estimate you described, power and memory. If it is a power supply, take a multimeter to test whether the current electricity voltage of your home is normal, and try to change the power supply if it is normal. If it's memory, you can unplug the memory and plug it in again, it's best to clean the gold finger part with an eraser, and if it doesn't work, try to replace it with a good memory module.

If the memory module self-test passes, it means that it is a memory problem, and if it still does not pass, it may be a memory slot problem. Floor. I laughed at the top of the list.

Can your computer be used normally after it keeps ringing? If you can, it is estimated that it is a few sounds when the machine is just turned on, which is normal, and a few sounds are the sounds of computer self-testing; If it is as you described, there is a problem, it should not be able to enter the desktop for normal use, you can check the corresponding parts of your computer according to the following:1

If the computer fails to pass the self-test, there are problems such as memory sticks and monitor sockets, you can replug and unplug them, or use a rubber to remove the gold finger part of the memory stick, which may be partially oxidized, resulting in poor contact. 2.If it is a "click" sound when it is turned on (like abnormal gear friction), this situation will make your computer boot very slow, and it will occasionally appear with a blue screen, and in serious cases, it will not be able to enter the system, which is called a ring disk, and you have to change the hard disk.

Note: Because I don't know much about the situation, it is difficult to make more judgments, please understand! Please describe your computer before mentioning computer-related problems, such as a desktop or a notebook, or some computer configurations, whether it is a discrete display, etc.

The computer has been turning on and the alarm has been ringing, don't worry, just plug and unplug this part again.
