After the computer is turned on, the host computer rings one long and three short, and the monitor d

1. Memory problems, solutions.

1. Use an eraser to wipe both sides of the gold finger of the memory and blow off the dust of the memory slot.

Dust removal with a hair dryer (or with an electric hair dryer).

Then try to boot it up.

If it's two sticks of memory.

That only install one to try.

Try one by one, if it's a memory and change the slot.

Second, the graphics card problem.

Use an eraser to wipe both sides of the gold finger of the graphics card clean and blow the dust off the memory slot.

Dust removal with a hair dryer (or with an electric hair dryer).

Then try to boot it up.

Don't scare them.

Absolute memory error Who said graphics card Don't believe it Borrow someone else's memory to try it If it's two memory Install only one try Try one by one.

Solution 1: Use toilet paper or eraser (preferably) to clean both sides of the gold finger of the memory, blow off the dust of the memory slot (preferably with a hair dryer), and then try to boot the second memory and change the slot.

Third, the memory is corrupted, the memory rarely has problems, because there is a sound, so it is judged that the memory is broken, and the general display does not light up, and the memory problem rarely directly indicates the sound of the memory error.

One long and three short is that your machine has hardware that is not plugged in, and you can disassemble it and plug it in again, rest assured that it will not be broken. . .

1. One long and three short is a problem with the graphics card, after making sure that the graphics card has no problems such as poor contact, you can reinstall the driver to try.

2. Also take into account the power supply problem, you change the new motherboard, graphics card, the new Dongdong may be a little more powerful, after a while before that kind of problem appears, it can be said that the power supply can't move it, change to a bigger better point and try again.

One long and three short. General memory errors, and another is that the keyboard controller is wrong, to put it bluntly, there is a problem with the motherboard, so change the motherboard.

It may also be that the keyboard is dirty, change the keyboard first, if you can't solve the motherboard repair).

It depends on the BIOS model.

Memory, keyboard, and graphics card are all possible.

You should first see if there is a problem with the keyboard, and if there is no problem, see if there is no problem and reinsert the memory module.

In fact, there are not many problems with graphics cards, because graphics cards are tightened with screws.

If there is an alarm on the host, it should be caused by poor hardware contact. Depending on the BIOS, the same alarm sound refers to different hardware. But most of them are poor contact between memory, graphics card, display, data cable and graphics card, and poor contact with the keyboard.

It is advisable for the landlord to inspect these parts.

Remove the main hardware and reinstall it, maybe the memory gold finger is dirty.

When the hard disk is turned on, there will be a sound of the hard disk reading, which is normal, but if the sound is too loud, it may be that the hard disk is faulty, if the hard disk is subjected to a large collision or often forcibly shut down, and the power is suddenly cut off during operation, etc., it will cause the hard disk to be damaged and make a sound, in this case, it is recommended to find a professional to check and repair, or directly replace it with a solid state drive.

The computer keeps ringing when it starts up (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

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 flash ram.

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

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 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.

Graphics card, pull out the wiping gold finger and plug it back in to see under the opening.
