2. The power supply and display are not properly connected to the graphics card. Check all the plugs.

Hehe, I've also encountered this problem, and I used a lot of methods to eliminate it, and finally found that I had to see that a wire in the chassis was broken, which caused the motherboard power supply to be insufficient, and the sound it made. So it is recommended that you go to the repair point to have a look.

Check the memory of the graphics card, unplug it when it is powered off, wipe the gold finger, and then install it, be sure to pay attention to the right slot! ~

Computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of the Internet, communications, and many other fields. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 10,000 to 59.4 million. The number of Internet users has reached 100 million, and there are 100 million mobile Internet users on the wireless Internet, including 100 million mobile Internet users, ranking first in the world.

The laptop won't turn on, and it rings. Most of them are memory module issues. This problem can be solved after disassembly and cleaning.

The common is a memory problem, find ** at home, you can take off the memory, listen to see if the sound is the same, the same words wipe the gold finger on the memory with an eraser and then install it to try it, or it is not the memory is not good, change it.

This kind of prompt indicates that the boot failed and that the hardware boot was unsuccessful.

1. Check whether the memory and the motherboard are plugged in well, whether the contacts are in good contact, clean the contacts and reinsert them into the motherboard.

2. Re-insert the graphics card into the motherboard and whether the contacts are in good contact with the motherboard, clean the contacts and reinsert them into the motherboard.

3. Check whether the CPU fan is not rotating and whether the CPU fan cable is plugged in;

4. After processing, restart to see, if it is still the same, there may be a problem with the hardware and need to be repaired.

The memory module is not in good contact, and the cash memory module wipes the metal finger, and it's fine

Hello, memory, hard disk, CPU, graphics card problems are all there. If you want to rule out the boot one by one,There is no display at all,It's likely to be a problem with the graphics card,On the contrary,If you can display the DOS screen,You can basically rule out the graphics card problem。

For the rest, if you have something, you can swap it out and try to see what the problem is. If you don't have anything, remove the memory, hard disk, CPU, and fan, and plug them in again one by one.

If you really can't figure it out, take it to the repair shop. After all, it's hard to tell if there's nothing to change.

A long sound means that the memory card is dropped or broken, and a short sound means that the graphics card is dropped or broken.

The first consideration is the memory, then the graphics card, the keyboard. You can rule it out one by one, and the motherboard sound is different for each model!

Just unplug the memory, wipe it, and plug it in.
