What is the problem with my computer ringing three times when it turns on

An important function of the motherboard BIOS is the POST power-on self-test program, after the microcomputer is connected to the power supply, the system will first check the main accessories such as the motherboard itself and the memory by the program, once the problem is found in the self-test, the system will give a prompt message or a whistle warning. For example, the specific meaning of the most common BIOS boot chirp is as follows for your reference:

award bios

1 Short: The system starts normally.

2 Short: Regular error.

1 long and 1 short: There is an error with the RAM or motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption.

Repeated long ringing: The memory module is not plugged in tightly or damaged, and the memory module is repeatedly ringing: There is a problem with the power supply.

If it's an AMI BIOS

1 short beep: Memory refresh failed.

2 short beeps: Memory ECC verification error.

3 short beeps: The self-test of the system basic memory (the first 64KB capacity) fails.

4 short beeps: The system clock is wrong.

5 short beeps: CPU error.

6 short beeps: Keyboard controller error.

7 short beeps: The real mode of the system is wrong and cannot enter the protection mode.

8 short beeps: Displays a memory error (e.g. displays memory corruption).

9 short beeps: Motherboard FlashROM or EPROM verification error (e.g. BIOS corrupted by CIH virus).

1 long and 3 short beeps: memory error (e.g. memory chip corruption).

1. Long and 8 short beeps: The display system is tested incorrectly (such as poor contact of the display data cable or graphics card).

If there is no problem with the BIOS self-test, most computers will have two or three screens on the boot screen, of which the first screen is the relevant information of the graphics card, such as the manufacturer, the type of display chip, the capacity of the video memory type, etc., if the information displayed here is different from the nominal indicators of the graphics card, then there is likely to be a problem with the graphics card.

There is a lot of information on the second screen, there are memory self-test instructions, BIOS information, etc., if there is a quality problem in the memory, then there will be a prompt here.

The box on the top half of the third screen will show the main configuration of the computer, and the lower part will show information such as the IRQ of the device in the PCI slot. If everything is in order, the operating system will boot after the third screen is displayed. Otherwise, there may be an error message related to the hard disk.

In addition to the boot display and BIOS information, almost all ATX motherboards now have the function of detecting CPU temperature, fan speed and power supply voltage, but to detect CPU temperature, you need to have a special temperature probe matched with the motherboard, and to detect the speed of the fan, you need to use a special fan with a three-pin power connector, and connect it to the corresponding three-pin fan connector on the motherboard. If there is a problem with these indicators, such as the CPU fan not turning, then there will be a clear indication during the self-test.

It feels like a memory module alarm.,If it's not a memory module then it's definitely the motherboard.。。

Is it a problem with the motherboard.

The system memory check failed.

The computer does not turn on the power due to the formation of an oxide layer on the surface of the gold finger of the memory and the independent graphics card, the memory is in poor contact with the memory slot, and the black screen cannot be connected to the power supply due to the poor contact between the graphics card and the graphics card slot.

Solution: First cut off the power, open the case, take out the memory, wipe it several times with the part of the eraser gold finger (that is, where there is a copper sheet), and then insert the memory slot (or replace the memory slot to insert it, if there is an independent graphics card, you can also use the same method to deal with the graphics card.

This answer works with most computer models such as the ASUS N56Xi323VZ-SL, Dell XPS13-9350-3708, etc.

When the computer is turned on, it rings one long and three short is:

Memory error. 1.The memory is not plugged in tightly. Plug it in. Reinsert it. Just plug it in and you're good to go.

2.If the memory is damaged, it can be replaced.

Depending on your situation. The boot display is not lit up (the system should be able to operate normally).It should be that the graphics card is not plugged in tightly. Plug it in. Reinsert it. Just plug it in and you're good to go. (But you need to wipe the gold finger of the graphics card clean).

A short sound of three sounds is not necessarily a matter of memory sticks, graphics card, power supply problems can lead to this phenomenon, now computer accessories, variety, thousands of differences, the previous way of listening to the fault is sometimes difficult to work, some time ago a friend's computer is like this, it is recommended to try the coms battery discharge!
