As soon as my computer is turned on, it makes a beeping sound, and the screen does not show a shadow

First of all, check each socket, it is best to pull it off and plug it in again, and listen to how many times it is announced. For your reference!

Now there are two kinds of BIOS commonly used in motherboards, "AMI and AWARD", and their definitions are slightly different due to different manufacturers.

1 Short: The system starts normally. Congratulations, there is nothing wrong with your 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.

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

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

Below is the alarm tone for the AMI BIOS**:

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: ROM BIOS check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

I don't know what type of alarm sound it is? But it's certain that the problem is with the memory or graphics card.

Please re-insert the graphics card or memory, and clean the dust in the slot, check whether the gold finger of the graphics card and memory is oxidized, if there is oxidation, you can use an eraser to gently wipe until the metallic luster is exposed.

Plug and unplug the power supply, keyboard, and memory again.

If you don't know how to use a computer, you might as well find someone to do it.

Specify the number and length of rings, as well as what kind of BIOS

Pull out the motherboard's battery and put it back on after five minutes.

1. If there is too much dust in the machine, and the contact is poor and causes a crash, check the CPU and graphics card for heat dissipation, dust removal, oiling, or replace the fan, you can clean the chassis and plug all the connections tightly.

2. If the screen is not displayed after turning on, it may be that the cable connecting the screen is loose, as long as you find the cable connecting the screen and plug it in!

3. If the cable is plugged in, but the screen and keyboard light are still not on, it may be caused by poor memory contact. You need to unplug the power supply and remove the screws on the left side of the chassis. Remove the left plate. Next to the fan of the motherboard, you can see 2 or more slots.

4. Replace the memory module, and after the change, boot it for testing. If it still doesn't work or you hear a long alarm sound, it means that the memory is not installed, plug it in again or try to plug it into another slot.

5. If the screen still does not light up and cannot be turned on after repeatedly plugging and unplugging the memory, it may be a problem with the graphics card. If it is a discrete graphics card, you can try to plug in the set display.

What should I do if the computer keeps making a dripping sound when it is turned on and the monitor does not light up?

Hello dear! We'll be happy to answer for you. What should I do if the computer keeps making a dripping sound when it is turned on and the monitor does not light up?

Answer: Generally, the memory is loose or the contact is poor, and there are many alarm sounds. 1. The main thing is that the memory or graphics card is loose, open the chassis and reinstall it again.

2. It is very likely that the internal board is in poor contact, disassemble and remove the garbage, and wipe the gold finger clean with an eraser. 3. If the status quo of the problem is changed in the state of no memory, you can try to clear the above methods, the problem may appear on the motherboard, you can use the "motherboard diagnostic card" to test the situation of the motherboard, or take it to the maintenance department to solve.
