What s going on with the ticking of the main computer case?

The computer will self-test if it doesn't pass, and the following is detailed.

1 Short: The system starts normally. There is nothing wrong with that.

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.

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

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

Is Dididi three tones? If so, the power supply is wrong.

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.

3. If you have an independent graphics card, you can also use the same method to deal with the graphics card, then insert it back into the graphics card slot, and finally install it, and restart the computer

The dripping sound from the computer host may be due to the following reasons:

Hardware failure. The dripping sound emitted by the computer host may be caused by a hardware failure, such as a hardware problem such as a memory module, graphics card, hard drive, etc., which will sound a warning sound.

BIOS settings digging. The sound of the main computer making a drop can also be due to a problem with the BIOS settings, such as a warning sound when the computer detects a hardware abnormality when it boots up.

The temperature is too high. The dripping sound emitted by the computer host can also be caused by the CPU temperature being too high, and the motherboard will sound a warning sound to protect the CPU from damage.

The workarounds are different for different reasons. If it is caused by hardware failure, you need to check whether the computer hardware is working properly, and replace or repair it if necessary. If you have a problem with the BIOS settings, you need to go to the BIOS page to set the settings.

If it is caused by high temperature, you need to clean the computer radiator and fan, or replace the radiator, fan and other hardware devices.

It should be noted that if the computer host emits a dripping sound, it should be checked and dealt with in time so as not to affect the normal use of the computer and the life of the hardware.

This situation can be taken into account.

The law of sound.

It could be a hardware issue.

Plug the memory and CPU back in and out first.
