Graphics card failure, analysis of the causes of graphics card failure

Graphics card failure: If the graphics card fails, the computer will have no display when it is turned on, the display screen is blurred, the handwriting cannot be seen clearly, the color display is abnormal, the machine crashes, and the graphics card driver is lost. If one of these conditions is occurring, there may be a problem with your graphics card.

Failure Analysis:

1. Poor contact of the graphics card slot The computer is often stuck, the mouse can move normally, and the mouse clicks very slowly, which means that the graphics card is malfunctioning, and this situation generally occurs only when the independent graphics card appears. Because the discrete graphics card needs to be plugged into the motherboard to drive the graphics card, it can be used. Then we need to analyze whether the graphics card and the socket are not in contact.

Solution: This situation is relatively easy and simple, first check the contact of the graphics card slot, and re-insert the graphics card. Secondly, check whether the fixed bezel of the graphics card is bent and deformed, whether the interface between the "gold finger" and the slot is stable, and whether the screws that fix the graphics card bezel are too loose or too tight.

If the VGA interface is not in good contact, the display will have color imbalance and color deficiency. Then you need to carefully check the VGA pins of the graphics card, and the on/off of the connecting cable, so that you can quickly find out the cause of the fault and eliminate it.

2. Graphics card incompatibility The problem of compatibility between computers can never be solved. The graphics card is the same here, if the graphics card is not compatible, then it is also one of the reasons why the graphics card fails. The incompatibility of the graphics card is mainly reflected in two aspects, it is the hardware and software, the software is mainly the driver is incompatible, and the hardware is mainly the phenomenon that the computer cannot be started and the black screen is the phenomenon, which means that the card itself is obviously incompatible with the motherboard.

Solution: Software incompatibility is generally mainly reflected in the graphics card driver, such as the driver is buggy and the driver is not installed. Then you should update the driver again and see if it can be troubled after the update.

If you save yourself the hassle, then reinstall the system. Some netizens also said that it is some users who are not familiar with BIOS operation and thus shield the driver, and it is recommended not to change the BIOS settings without authorization. Parameter.

If the problem persists, try to change to a different graphics card and install the graphics card driver. After installation, log in to the game to see if there are any improvements in the graphics. If the monitor returns to normal, it is probably related to the compatibility of the graphics card.

The hardware is not compatible with the motherboard, which is generally caused by insufficient current supply capacity between chips or in the power supply return circuit of the graphics card.

After the above inspection, if you find that the display is still very slow, it means that the graphics card has been damaged. Then you can only replace a new graphics card to troubleshoot the graphics card.

A lot of people who are not very proficient in computers'People are generally afraid of problems with graphics cards, CPUs, etc., and they tremble when there is a problem with the graphics card. In fact, this kind of failure is usually caused by poor contact between the graphics card and the motherboard or a problem with the motherboard slot. For some motherboards with integrated graphics cards, if the video memory shares the main memory, you need to pay attention to the location of the memory module, and generally there should be a memory module inserted on the first memory module slot.

There is no display failure when booting due to the graphics card, and there will generally be one long and two short beeps after booting (for Award BIOS graphics cards).

Common fault 1: crashes

This type of failure is generally common in the incompatibility between the motherboard and the graphics card or the poor contact between the motherboard and the graphics card; Incompatibility of the graphics card with other expansion cards can also cause crashes.

Common fault 2: The screen is abnormally noisy or patterned

This type of failure is usually caused by a problem with the graphics card's video memory or poor contact between the graphics card and the motherboard. You need to clean the gold finger of the graphics card or replace the graphics card.

Common fault 3: The graphics card driver is missing

The graphics card driver is loaded, and the driver is automatically lost after running for a period of time, this kind of failure is generally due to the poor quality of the graphics card or the graphics card is not compatible with the motherboard, which makes the graphics card too hot, resulting in unstable system operation or crash, at this time the only way to replace the graphics card.

In addition, there is a special case where the graphics driver used to be loaded, but after the graphics driver was loaded, it crashed when entering Windows. Replace the graphics card of other models and insert the old graphics card after loading its drivers. If this failure does not resolve the problem, the registry is faulty, and the registry can be restored or the operating system can be reinstalled.

Common fault 4: The screen is displayed and the handwriting cannot be seen clearly

This type of failure is usually caused by the display or graphics card not supporting high resolution. When the screen is blurred, you can switch the boot mode to safe mode, and then enter the display settings under Windows 98, and click the "Apply" and "OK" buttons in the 16-color state. Reboot, delete the graphics card driver in Windows 98 normal mode, and restart the computer.

You can also not enter the safe mode, in the pure DOS environment, the file will be changed to after the save exit, and then update the driver in Windows.

Common fault 5: The color display is abnormal, and this type of fault generally has the following reasons:

1.The graphics card is in poor contact with the display signal cable.

2.The monitor itself is faulty.

3.In some software, the color is not normal when running, usually in older machines, there is an option to verify the color in the BIOS, just turn it on.

4.The graphics card is damaged;

5.The display is magnetized, which is usually caused by being too close to an object with magnetic properties, and the magnetization may also cause the display to be deflected.

Summary. Causes and solutions:

1. The memory is too small.

Some large games occupy a large amount of memory when running, and if the memory is insufficient, it is easy to cause a memory overflow and cause a blue screen, and the best solution is to increase the memory module.

Second, the computer is overheating.

Some games with high requirements for computer configuration require a large number of calculations on the graphics card and processor when running, which will generate a lot of heat, and if the heat dissipation of the computer is not good, it is easy to overheat the hardware and cause the blue screen of death. The solution is to dust the computer and improve the cooling performance of the computer.

Manifestations of graphics card failures.

Hello, I'm here to solve this problem. There are many manifestations of graphics card failure: there is no display at boot, the computer crashes, the display shows that Yan Hong's color is abnormal, and the shield shows abnormal staring noise or patterns on the mountain curtain, which are all manifestations of graphics card failure.

If you have any questions, feel free to come to me.

My computer, a newly bought second-hand machine, playing small games, such as dnf cf, is no problem, playing Naraka: Bladepoint GTA will have a blue screen or stuck, and the task manager has no response, and the two memory sticks have been peeled and removed, and there will be a situation like this with either one.

Pro, this is under-specified, because Naraka: Bladepoint and GTA are both high-spec games.

My configuration is enough for i5 10400 1060 5g 16g RAM.

That should be if you don't have the graphics driver installed.

Newly installed drivers on the official website.

That could be the wrong one, you installed the 1060 driver.

Like. I'm playing CF and it's blue screen again.

Causes and solutions: 1. Some large games with too small memory are large in the internal cultivation of the brigade when running, and if the memory is insufficient, it is easy to cause memory overflow and cause a blue screen, and the best solution is to increase the memory module. Second, the computer is overheated, some games with high requirements for computer configuration require the graphics card and processor to perform a lot of calculations when running on the wide bench, which will generate a lot of heat, and if the heat dissipation of the computer is not good, it is easy to overheat the hardware and cause the blue screen of death.

The solution is to dust the computer and improve the cooling performance of the computer.
