The computer can t be turned on, and the alarm keeps beeping 1 time every 20 seconds, and the monito

Check the memory, graphics card or something is not in good contact.

Open the case, unplug the memory module, and plug it in. Try it.

When the computer is first turned on, the sound from the inside of the case is a sound prompt from the BIOS when it detects a fault during the self-test.

The reasons why our computer will beep three times when it is turned on are generally divided into the following situations:

1. One short: the system starts normally.

2. Two shorts: The CMOS is set incorrectly and needs to be set again.

3. One long and one short: the memory or motherboard is wrong.

4. One long and two short: The monitor or graphics card is wrong.

5. One long and three short: the keyboard controller is wrong.

6. One long and nine short: The flashram or EPROM of the motherboard BIOS is wrong.

In addition, the computer will make other sounds when it is turned on, and the specific performance and corresponding problems are as follows:

1. Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

2. Non-stop ringing: the power supply and display are not connected to the graphics card. Check all the plugs.

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

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

You can judge what is wrong with our computer by the situation of different three beeps of the computer, and if it can't be solved by itself, it will be sent for repair.

memory, wipe it and plug it back in,

Generally, the memory module is not plugged in properly.

It should be the hardware reason, and the specific depends on how the alarm is made.

During the POST, if a fault occurs in the computer, it sometimes rings continuously, and different rings represent different error messages.

awardbios

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please enter CMOS

setup, resetting the incorrect option.

1 long and 1 short: There is an error in the memory 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 and 9 short: motherboard flash

RAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

amibios

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

2 Short: The memory ECC verification error is incorrect. in CMOS

Setup can solve the problem by setting the memory to disabled for ECC checksum, but the most fundamental solution is to replace a memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

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: BIOS chip 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.

You can't answer this question.

There are many reasons for this.

The memory motherboard can cause regular errors.

Monitors or graphics cards can also cause and so on.

You'd better go to the pits.

Changming is that the motherboard self-test has not passed, that is, these standard devices have not worked normally, mainly CPU, memory sticks, if the replacement is not good, it is the motherboard interface is broken, and it has little to do with the CPU fan.

It could be a problem with the graphics card! Take out the graphics card and wipe it off! If only you could adopt me! Thank you.

The alarm keeps alarming, or is there a problem with the power supply information transmission of the memory module or the motherboard memory slot.

It is recommended to send it to a professional repair shop!

One long and two short is a problem with the graphics card, and a long sound is the motherboard or memory. Let's change the memory and see if the memory is broken.

Or is it a memory or motherboard issue, a fan issue may whistle, but it can still boot.

Fault cause: The fault of memory alarm is common, mainly caused by poor memory contact. For example, the memory module is not standardized, the memory module is a bit thin, and when the memory is inserted into the memory slot, there is a certain gap; The gold finger process of the memory module is poor, and the surface of the gold finger is poorly plated, and after a long time, the oxide layer on the surface of the gold finger gradually thickens, resulting in poor memory contact; The memory slots are of poor quality, the reeds are not in contact with the gold fingers of the memory sticks, etc.

Solution: Open the case, carefully wipe the gold finger of the memory module with an eraser, remove the memory module and insert it again, and fill the gaps on both sides of the memory slot with hot melt adhesive to prevent continued oxidation during use.

Note: Be sure to unplug the main unit and fold the power cord when plugging and unplugging memory modules to prevent accidental memory burning.

Or the memory is not plugged in well, and some have to be plugged in pairs.

2. The host has a fault, and the cause of the failure can be judged according to the different conditions of the alarm sound, as follows:

1) award bios

1 Short: The system starts normally. 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 in the memory 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 flashram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

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