Computer graphics card failure 40, computer graphics card failure

First of all, I suspect that the interface part of your monitor and the graphics card is not in good contact Check it out.

Second, wipe the gold finger of the graphics card clean with an eraser, and then check whether the heat dissipation of the graphics card and the fan are normal.

Third, unplug the memory (probably not a memory problem, just in case, let's do it) unplug it and wipe the gold finger and plug it into the board well.

If you have done all of the above, there are still problems, it is recommended that you change the graphics card, it may be that there is a problem with some wiring of the graphics card or a problem with the chip, and sometimes the graphics card is broken, and you can also pass the self-test.

And then there is the problem of the board, 80% is not the fault of the board, it is recommended that you still repair it at home, use the card to test for you, my old computer is turned on and self-checked, and the power suddenly goes off and can not enter the system.

Are you sure it's a discrete display? It is possible that the graphics card is overheated, and the fan of the graphics card is changed.

It won't be a problem with the graphics card, if there is a problem with the graphics card, you won't be able to boot it at all, and the hardware will not pass when you boot it, and it will alarm.

I think the problem can be between the connections of the various hardware. You rearrange the cables, and then take the fan apart to clean up the dust, and if there is still a problem after doing this, it means that there is a problem with your hardware. Then you can remove the memory module and use an eraser to remove the oxide film from the gold finger.

Try to see if that solves the problem.

It is estimated that the contact of the graphics card is poor, so reinsert it. The memory module is also reinserted.

1. If your computer's graphics card is not completely broken, then the symptoms are as follows: it can be turned on normally.

And it can use small software normally, such as office, and can also operate normally on the Internet. In short, there is no problem with the operation of the general basics.

2. When your computer's graphics card is completely damaged, the first thing it means is that your computer cannot be turned on normally. When the computer is turned on, we will see the words "No Signal" on the screen of the monitor.

2. Summary of the symptoms of a broken graphics card, 1The computer monitor does not respond, and the screen is completely black when turned on.

Or there is a ticking sound, 2The display color is not normal, 3Crash.

A flower screen appears inside. I can't read the handwriting.

Common fault 1: No display is displayed when the computer is turned on

This type of failure is usually caused by poor contact between the graphics card and the motherboard or a faulty 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 2: The screen is blurred, 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.

It is also possible not to enter the safe mode in a pure DOS environment.

file, change it to , save it to exit, and then update the driver in Windows.

Common fault 3: The color display is abnormal, and this kind 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, which is common in older machines, and there is a color check in the BIOS'option, 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.

Common fault 4: Crash

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 5: Abnormal noise or pattern appears on the screen

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 6: 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.
