The computer is turned on and the memory rings 2 times, and I can t get into the screen, what s goin

2 Short: Memory ECC verification error. In CMOS Setup, you can solve the problem by setting the memory option for ECC check to Disable D, but the most fundamental solution is to replace a memory.

Please check it.

Use an eraser to wipe the gold finger of the memory and try it out, if it's 2 memory, change the slot.

Ringing twice? A factory reset of the BIOS will do.

If it's a long and two short tones, check the graphics card.

The memory is loose and reassembled.

1 Reboot.

2. The machine can't be turned on, and the light can't be lit, and many of the reasons are hardware problems.

3. The memory has been moved, and there is an alarm sound, which means that the memory is not plugged in or the memory is damaged, and there is a problem with the motherboard memory slot.

4. It is recommended to wipe the gold finger of the memory, reinsert it and turn it on.

5. It still can't be opened, insert the memory into another slot, and try multiple memories one by one.

6. Different alarm sounds represent different faults, and the right medicine can also solve the problem. Hope it works for you;

AMI BIOS Alarm Sound Meaning.

1. Short: Memory flush failed.

2 Short: Memory ECC verification error.

3 Short System base memory (first 64kb) check failed.

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: Shows a memory error (shows that the memory may be broken).

9. Short ROM BIOS checksum error.

1 long 3 short memory error (memory corruption, please replace).

1. Long 8 short display test error (the monitor data cable is loose or the graphics card is not plugged in steadily).

Award (Phoenix) BIOS Alarm Sound Meaning (Version number is different from old to new, and the meaning of the alarm sound is different).

No alarm sound: There may be a problem with the power supply, motherboard, or PC speaker. Check whether they are in contact with each other or replace the corresponding parts.

1 short tone: This is the normal tone.

2 short tones: Caused by the wrong CMOS setting, re-set the CMOS, generally call the default settings.

1 long and 1 short: The memory and motherboard are faulty, which is generally a compatibility problem, and the memory is replugged and unplugged.

1 long and 2 short: The display is wrong, generally because the graphics card is in poor contact with the AGP slot, or the display data is connected at the end, or it may be that the graphics card or video memory is physically damaged.

1 long and 3 short: The keyboard controller is incorrect, first try to change the keyboard.

1 long 9 short: Motherboard flashram or EPROM error (BIOS chip is damaged), try to replace or re-flash.

Long ringing: The memory module is inserted at the end or is not in good contact, it has been damaged, and the memory is re-inserted or replaced.

Ringing: The power supply and the monitor are not properly connected to the graphics card.

Repeat Short Ring: Power.

No Sound No Display: Power.

High frequency alarm during operation: The CPU is overheating, often due to overclocking, please check whether the CPU fan is running normally.

In general, it is caused by the memory not being plugged in.

Memory problems, the memory is broken or the contact is not enough, how to deal with it: unplug the memory in the correct way in the case of power failure, and blow it clean. Also, when you have 2 memory modules, you can pull out one of them first to see if it can work properly.

If it is broken, it is good to replace it with a good memory module.

The system configuration is not high, or it has been phased out, and the running time is too long.

It's possible. Turn the power off, plug it back in, and give it a try.

The computer starts up three times, and the monitor has no signal, which generally has the following situations:

1. Loose memory modules, poor contact, and dust accumulation will cause the screen to not be displayed and not started.

Solution: Unplug the power supply, remove the memory module, remove the floating dust at the interface with an eraser, and wipe it clean with letter paper.

2. Loose graphics card, poor contact, and dust accumulation will cause the screen not to be displayed and the computer not to start.

Solution: Unplug the power supply, remove the graphics card, remove the floating dust at the interface with an eraser, and wipe it clean with a letter paper. Align the graphics card, press down and fix it, and you're good to go.

3. Motherboard problem, solution: unplug the power supply, remove the motherboard battery, jump the CMOS jumper, and jump to"colse"position, hold for more than five minutes, install the battery, and resume the jumper. That's it.

After power-off, remove the memory, erase the gold finger with an eraser, and then reset and restart it.

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 option.

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: There is a problem with the power supply.

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

Hope it helps.

The memory is fine, that is, there is a problem with your master. The graphics card is unplugged and is being plugged in.

The keyboard controller is wrong, the keyboard is broken, or the motherboard keyboard controller is broken, try to change the keyboard.

Remove the fan, take out the CPU, see if there is oxidation, you can wipe it with an eraser to remove the oxide layer.

Listen to you about the power supply fan.

When the computer is turned on, the demand for power supply is relatively small, and the fan will slow down, so that the noise generated is relatively small.

In addition, the quality of your power supply fan itself is not good, and the friction is relatively large when the fan rotates, which causes a lot of noise.

Another thing is that the lubricating oil of the power supply fan is dry, and the friction is large when it is just turned on, and when it runs for a while, it generates heat and melts the lubricating oil, which plays a role in lubrication, so that the sound is smaller.

In fact, the problem you said is very common, and it does not affect the computer too much, if you don't like the noise, go to change a power fan, but it costs a lot of silver, I am very reluctant to change in this case, if you want to add lubricating oil, then you don't have to try, it is not good to add, it is estimated that the probability of failure is 100%, it is best not to try, don't make the last fire, and the power supply is not repaired by others. That's all I have to say.
