A computer is a machine that uses electronic principles to process data according to a series of instructions. A computer can be divided into two parts: a software system and a hardware system.

The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania in the United States on February 15, 1946.

People refer to computers without any software installed as bare metal. With the development of science and technology, some new types of computers have emerged: biological computers, photonic computers, quantum computers, etc. On May 24, 1954, the transistor electronic computer was born.

The first generation of computers had a very limited variety of input and output devices. The usual input device is a card reader that punches cards, which is used to import instructions and data into memory; The output device used to store the results is typically tape. With the advancement of science and technology, the abundance of input and output devices has been improved.

Take a personal computer, for example: the keyboard and mouse are the main tools for users to input information directly into the computer, while monitors, printers, amplifiers, and headphones return processing results. In addition, there are many input devices that can accept other different kinds of information, such as digital cameras that can input images.

Among the I/O devices, there are two categories that are worth noting: the first is secondary storage devices such as hard disks, optical discs, or other devices that are slow but have a high capacity. The second is computer network access devices, through which the direct data transfer between computers greatly enhances the value of computers.

Today, the Internet has enabled tens of millions of computers to transmit various types of data to each other.

1@You can use the driver life to uninstall the original installed graphics card in the computer to avoid the existence of residual items. Wait for the uninstallation to be completed, and then perform a complete test on the computer with Driver Life, and reinstall it after the detection.

2@Sometimes some graphics drivers are incompatible with the computer or some software in the computer. At this time, we need to check whether the graphics card is fully inserted into the agp slot, whether the computer is blocked by a firewall, or whether the graphics card driver conflicts with the computer system version.

3@In addition to the above methods, writing BIOS settings in the computer will also cause problems with the installation of the graphics card driver in the computer. Generally, you can press the DEL key to enter the BIOS settings. Find the "Chipset Features Setup" option, set "Assign IRQ to VGA" to "Enable", and then save to exit.

When this is set to "disable", many drivers may not be installed.

1. You can use the driver disc you brought when you purchased the machine to install the complete driver.

3. Use third-party software to update drivers.

2. Find "Hardware Detection" in the toolbox.

3. Click "Driver Installation" in the hardware test.

4. You can see the "installation status", if it is not installed, you can click to install it directly.
