When the computer starts, there is a three short and five long alarm tone, asking the reason

Is there an antivirus software prompt?

If there is a problem with the computer's memory, you can deal with the memory module at this time.

Open the case, remove the memory module, and gently wipe the side of the memory module inserted into the card slot with your hand or an eraser.

Reload the memory module into the memory card slot, install the case cover, and turn it back on, and in most cases it will work normally.

A memory module is a part of a computer that can be addressed by the CPU and can be read and written. Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

Memory modules are an essential part of a computer, and the CPU can address the memory through the data bus. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory. Later computers will not have main memory on the motherboard, and the CPU will rely entirely on memory modules.

All content on external memory must pass through memory in order to function.

Detailed explanation of the alarm sound of different brands of BIOS:

You can tell what the problem is based on the length and number of alarms.

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 options.

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

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

No sound, no display: Power issue.
