How to look at the hardware configuration? Experts share hardware knowledge

You may have used it for so long. The computer doesn't know how to configure your computer. You don't know how to look at it. In fact, it's very simple. You can watch it when you boot it. Here is a tutorial to show you how to look at yourself. The method of computer configuration.

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 reach down and hold the "PAUSE” key).

1. Graphics card information

The hardware that is checked first during the power-on self-test is the graphics card. Therefore, after the machine is started, several lines of text appearing in the upper left corner of the screen are the graphics card's “Personal Data”. Introduction (the first line of the four lines of text, GeForce4 MX440……” indicates that the display core of the graphics card is GeForce4 MX440, supports AGP 8X technology; the second line "Version……" indicates the graphics card BIOS Version, we can update the graphics card BIOS version & ldquo; extract & rdquo; graphics performance, of course, this line of text will also change after the update; the third line "Copyright (C) & helip; … & rdquo; is the copyright of the manufacturer The information indicates the copyright period of the display chip manufacturer and manufacturer; the fourth line “64.0MB RAM” indicates the memory capacity of the graphics card.

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

After displaying the basic information of the graphics card, the second self-test screen that appears next shows more hardware information, such as CPU model, frequency, memory capacity, hard disk and CD-ROM information. It 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 understand, of course, the motherboard chipset; the next few lines of text indicate The CPU frequency and memory capacity and speed. Oh, my CPU and memory are overclocked, so the frequency can be less formal; the following four lines "IDE……" indicate that the connection is on the IDE master-slave interface. The device, including the hard disk model and optical drive model, etc.

3. Motherboard information

At the bottom of the second self-test screen, there will also be a line of information about the motherboard. The current BIOS update date of the motherboard, the following symbol is the code used by the motherboard, according to the code we can understand the motherboard chipset model and manufacturer. In the past, the old motherboard's self-test screen in the middle of the text below the middle of the text It is the motherboard chipset. This board refers to it above the self-test screen.

After the machine is started, press the “DEL” button to enter the BIOS setup page. In this information, you can also see the hardware information of the machine, which is no different from the one displayed on the startup screen.

Second, use the device manager to view the hardware configuration

After entering the operating system, install the hardware. In the case of drivers, you can also use the Device Manager and DirectX Diagnostic Tools to view the hardware configuration. Let's look at how to use the device manager to view hardware information. Go to the desktop, right click on the "My Computer" icon, select "ldquo; Properties" from the menu that appears, open the "System Properties" window, click on "Hardware--Device Manager", at &ldquo The Device Manager shows all the hardware devices in the machine configuration. From the top to the bottom, the optical drive, disk controller chip, CPU, disk drive, display, keyboard, sound and video are arranged in order, and the bottom is the display card. . To find out which kind of hardware information you want, just click on “+” in front of it to expand the content below it.

In addition to the general hardware information, you can learn more about the motherboard chip, sound card and hard disk working mode. For example, if you want to view the working mode of the hard disk, just double-click the corresponding IDE channel to pop up the property window. In the property window, you can check the device type and transfer mode of the hard disk. These are not available on the boot screen.

It should be noted that the device manager provided in the operating system before Windows XP can not be used to view the CPU operating frequency. Fortunately, we also have DirectX diagnostic tools.
