Analysis of several computer hardware common sense that must be known

When we use a computer, we will care about how the software works. But in fact, it is necessary to know some hardware knowledge if you use the system well. So this tutorial has compiled some common sense that computer hardware must know today. The details are as follows:

The most feared thing about the computer is that the computer has failed. The most annoying thing is that frequent failures occur. The most anxious thing is that there is a fault but there is no reason to find something wrong. What is even more embarrassing is that there is a fault, and a friend is found to help repair it. At first glance, it is a small problem. It is not a fault. General common sense problems, I don't understand myself. Let's take a look at some of the most common, simple, and most cumbersome problems that are most common to the computer.

1: The display does not respond. Most of them are caused by memory, and it may be that gold fingers are oxidized and loose.

2: English tips appear. Content such as "SYS……, DISK……” etc. SYS…… no system or system is not working properly. DISK is a hard disk prompt, generally the connection is not normal, including the hard disk power, the data cable is not connected.

3: Automatic restart, crash. This type of problem often occurs on the CPU and power supply, often caused by excessive temperature and poor heat dissipation.

4: Flower screen, jitter. Under normal circumstances, the graphics card is not connected well, including the graphics card is not plugged in, and the display is not good. Another possibility is caused by static electricity, which can be solved by means of a grounding wire.

5: The system is running slowly. In general, it is recommended to reinstall the system for three months to six months, and it is a fully formatted installation system. The current virus is very embarrassing, and can not be anti-virus software, anti-virus software is not a panacea. Many viruses have entered the state where the hardware resides. Generally, antivirus cannot be completely removed. Therefore, in the maintenance process, you will often see service-conscious maintenance personnel to disassemble the system when installing the system, and discharge the memory board to discharge the virus.

6: Hard disk problem: There is a continuous slight kaka sound, which proves that your hard disk has bad sectors and needs to be repaired or replaced in time.

7: Common computer alarm:

(1) 1 short; normal detection, but also prove that your computer hardware is OK.

(2); A long sound is uninterrupted; this indicates that there is a problem with your memory, or it is loose and not installed.

(3); one long and two short; the graphics card is not connected or loose or gold finger oxidation.

These are just some basic hardware knowledge. If you want to understand more about this content, you usually have to accumulate more. The hardware may be stranger to everyone, but it is ok to look at some information. .
