This article mainly explains "the common faults of computer graphics cards and how to solve them". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. let's follow the editor's train of thought to study and learn "the common faults of computer graphics cards and how to solve them".

Common failure 1: no display when booting

This kind of failure is usually caused by poor contact between the video card and the motherboard or a problem with the motherboard slot. For some motherboards with integrated video cards, if the video memory shares the main memory, you should pay attention to the location of the memory bar, which should be inserted into the first memory slot. Due to the boot failure caused by the video card, there is usually a long or two short beep sound (for the AWARD BIOS video card).

Common malfunction 2: displaying a blurred screen, unable to see the handwriting clearly

This type of failure is usually caused by the display or video card that does not support high resolution. When the screen is blurred, you can switch the startup mode to safe mode, then enter the display setting under Windows 98, and click the "apply" and "OK" buttons in the 16-color state. Restart, delete the video card driver in the normal mode of the Windows 98 system and restart the computer. You can also not enter the safe mode, in the pure DOS environment, edit the SYSTEM.INI file, change display.drv=pnpdrver to display.drv=vga.drv, save and exit, and then update the driver in Windows.

Common fault 3: abnormal color display

This type of failure generally has the following reasons:

1. Poor contact between display card and display signal line

2. The fault of the monitor itself

3. The color is not normal when running in some software, which is generally common in older machines. There is an option to check the color in BIOS, which can be turned on.

4. Video card damage

5. The display is magnetized, this kind of phenomenon is generally caused by being too close to the object with magnetic properties, and the magnetization may also cause the display screen to deflect.

Common failure 4: crash

This kind of failure is generally seen in the incompatibility between the motherboard and the graphics card or the poor contact between the motherboard and the graphics card; the incompatibility between the graphics card and other expansion cards will also cause a panic.

Common failure 5: abnormal spots or patterns appear on the screen

This kind of failure is generally caused by problems with the video memory of the video card or poor contact between the video card and the motherboard. The gold finger of the video card needs to be cleaned or the video card needs to be replaced.

Common failure 6: video card driver lost

The driver of the video card is loaded, and the driver is lost automatically after running for a period of time. This kind of fault is generally due to the poor quality of the video card or the incompatibility between the video card and the motherboard, which makes the temperature of the video card too high, resulting in unstable operation of the system or a crash. At this time, only the video card can be replaced.

In addition, there is a special case in which the video card driver can be loaded before, but the panic occurs when entering the Windows after the video card driver is loaded. Can replace other types of graphics card after loading its driver, insert the old video card to solve. If you can not solve this kind of failure, then explain the registry failure, restore the registry or reinstall the operating system.

Thank you for your reading. the above is the content of "the common faults of computer graphics cards and how to solve them". After the study of this article, I believe you have a deeper understanding of the common faults of computer graphics cards and how to solve this problem. the specific use of the situation also needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
