Clearly understand the configuration of the computer hardware (1)

For old users who use computers for a long time, it is inevitable to go to a friend or colleague to help maintain and repair the computer, and sometimes to help people buy a PC. At this time, we will definitely bring hardware detection software, but no one can Always carry these software with you, what if you don't have the right detection software on hand? Can't always know nothing about it? That way, your master image is damaged. In fact, we can clearly understand the configuration of the computer hardware when we leave the software. Let's take a look at it together.

First, check the hardware configuration in the power-on self-test

After the machine is assembled, even if the operating system is not installed, the power-on test can be performed. In the screen of the power-on self-test, the hardware configuration is hidden. A brief introduction (because the boot screen flashes over, if you want to see it clearly, remember to hold down the "PAUSE" button in time).

1. Graphics card information

The hardware that is checked first during the power-on self-test is the graphics card. Therefore, several lines of text appearing in the upper left corner of the screen after starting the machine are the "personal data" introduction of the video card. In the four lines of text, the first line "GeForce4MX440..." indicates that the display core of the graphics card is GeForce4MX440 and supports AGP8X technology; the second line "Version..." indicates the BIOS version of the graphics card. We can update the BIOS version of the graphics card. "The performance of the graphics card, of course, this line of text will also change after the update; the third line "Copyright (C) ..." is the copyright information of the manufacturer, indicating the copyright period of the display chip manufacturer and manufacturer; the fourth line " 64.0MBRAM" indicates the graphics memory capacity.

2.CPU and hard disk, memory, CD-ROM information

After displaying the basic information of the video card, the second self-test screen that appears next shows more hardware information, like CPU model, frequency, memory capacity, hard disk and CD-ROM information will appear in this screen. The top two lines of the screen indicate the BIOS version of the motherboard and the copyright information of the BIOS manufacturer; the next text will be understood at a glance, of course, the motherboard chipset; the next few lines of text indicate the CPU frequency and memory. Capacity, speed. Oh, my CPU and memory are overclocked, so the frequency can be less formal; the following four lines "IDE..." indicate the devices connected to the IDE master-slave interface, including the hard disk model and optical drive model.

3. Motherboard information

There will also be a line of information about the motherboard at the bottom of the second self-test screen. The previous date shows the current BIOS update date of the motherboard. The symbol is the code used by the motherboard. According to the code, we can understand the chipset model and manufacturer of the motherboard. In the past, the middle of the lowermost text in the self-test screen of the old motherboard is marked with the motherboard chipset, which is mentioned above the self-test screen.

After the machine is started, press the “DEL” button to enter the BIOS setup page. You can also see the hardware information of the machine in the basic information, which is no different from the boot screen.
