What is the reason why the graphics card turns crazy when the computer boots up, but it can t be tur

First, check the capacitance of the motherboard (you should know what it is, right?). Black, columnar kind of thing).

See if there is a bulge phenomenon at the top, if there is, take it to the place where the computer is repaired, let him help you change it, don't say that there is anything wrong with your computer, just say that it is to change the capacitor, and he does not dare to charge too much money.

The capacitor bulge must be replaced as soon as possible.

The gold fingers of the graphics card and memory can be wiped clean with an eraser, and the dust on them can be swept with a small brush.

Is the memory the same model? If not, don't plug in dual channels (i.e. in 1-3 or 2-4 memory slots) and plug in 12 or 34 slots.

If that doesn't work, then try using only one memory, and after a while, if it's okay, try using another one.

If it's okay to plug in only one, but not two, then it should be that the memory compatibility is not good, and it doesn't matter if you use one memory. 512 memory for ordinary applications is sufficient.

Also, check if the graphics card's fan is still spinning (if any), and unplug the fan's power cord if it doesn't. It's best to get another one.

It can't be turned on, and there is also a possibility that the CPU is in poor contact (mostly old computers). Often take out the CPU and then install it back to turn on (in the past, when I was in high school, the old machine in the school computer room often had this problem) ......

How to take out the CPU, first open the heatsink buckle (different models have different buckles, study and study by yourself).

Pull a metal (some may be plastic) stick next to it, pull it aside slightly and then move it up to take out the CPU, and after taking it out, sweep the CPU socket with a brush, being careful not to leave hair. Then install it back as it is, remember to plug in the CPU fan!

Note! After taking out the CPU, carefully place it on a flat place such as a tabletop, and don't bend the pins! When installing, you can't press hard, there is a triangle arrow in the corner of the CPU, and the triangle arrow at the corresponding slot is installed in the direction of the triangle arrow, and you can't press it hard if the direction is wrong!

Causes and solutions:

1. The memory module is loose or damaged.

Solution: Use an eraser to wipe the gold finger of the memory module and reinsert the memory stick; Replace the memory module.

2. Poor contact of the graphics card.

Solution: Same as memory method.

3. The main engine is short-circuited.

Workaround: Clean up the host and replug the wiring.

4. Motherboard BIOS problems.

The motherboard BIOS stores important hardware data, and if it fails, it can cause the computer to not boot.

Solution: Go to the motherboard BIOS settings page and restore the BIOS to the default value.

When the computer boots up and the display does not light up, and the fan of the pure card is spinning, it may be caused by the following reasons:

Graphics card connection question: Check that the graphics card is properly plugged into the motherboard and that the power supply and monitor are connected.

Display connection issues: Check that the monitor is connected to the correct port and that the monitor is powered on.

Graphics card power issues: Check that the graphics card is properly connected to the power supply and that the power supply** is stable.

Graphics driver issues: If the graphics driver is faulty or conflicting, it can also cause the computer's boot display to not light up. You can try uninstalling the graphics driver and then reinstalling the latest version of the driver.

Graphics card hardware failure: If none of the above methods can solve the problem, it may be caused by a graphics card hardware failure. The graphics card needs to be replaced or sent in for repair.

It should be noted that care must be taken when operating the computer hardware to avoid further damage to the hardware. If you're not sure how to do it, you can seek help from a professional.

1. The connection cable between the monitor and the graphics card is damaged.

2. The gold finger of the graphics card is oxidized or not fully inserted into the slot.

Hello dear, according to your problem description: Problem: The graphics card suddenly spins wildly and can't turn on.

Possible causes:1The graphics card's cooling system fails or there is too much dust, resulting in high temperatures, and the graphics card's fan spins wildly, or even fails to boot properly.

2.There is an error or conflict in the graphics card driver that prevents the computer from booting properly. 3.

The power cord of the graphics card is loose or damaged, causing the graphics card to fail to power properly. Workaround:1

Clean or replace the heatsink of the graphics card, and clean the dust inside the case in time to ensure good heat dissipation. 2.Start your computer in safe mode, uninstall and re-install the graphics driver, and make sure the driver is correct.

3.Check that the power cord of the graphics card is tightly connected, and if it is damaged, replace it with a suitable power cord. The above three situations are the main reasons why the graphics card suddenly spins wildly and cannot boot, and users should first rule out these possibilities when solving this problem.

In addition, when using computers in the state, attention should be paid to cleaning up dust in time, regular maintenance and checking whether the hardware connection is loose, so as to reduce the occurrence of hardware failure. If the above measures do not solve the problem, it is recommended to seek professional help or replace the graphics card.

Summary. Generally, the reasons why the graphics card can't turn on the machine are as follows:1

If the graphics card driver is faulty, the driver will also have problems under normal circumstances, you can try to reinstall the available driver; 2.If the motherboard of the computer is damaged, you can check whether the power supply is normal, or check whether the temperature of the motherboard is too high; 3.If the graphics card is damaged, you can check the heating of the graphics card, and if the temperature of the graphics card is too high, you can try to replace it with another one.

Finally, if your computer still doesn't boot properly, you can try to disassemble the computer again, check the internal interfaces and connections of the computer, and make sure that there are no problems with the connection and socket reset inside the computer.

It was all of a sudden while playing a game.

Generally, the reason why the graphics card can't turn on the machine is as follows:1If the graphics card driver fails, there will be problems with the driver under the orange chain in general, you can try to reinstall the driver available to Yuanjiansun; 2.

If the motherboard of the computer is damaged, you can check whether the power supply is normal, or check whether the temperature of the motherboard is too high; 3.If the graphics card is damaged, you can check the heating of the graphics card, and if the temperature of the graphics card is too high, you can try to replace it with another one. Finally, if your computer still doesn't boot properly, you can try to disassemble the computer again, check the internal interfaces and connections of the computer, and make sure that there are no problems with the connection and socket reset inside the computer.

Summary. You're talking about this because the console doesn't really boot up, it's just powered up. There are several reasons for this:

1. Power supply problems.

2. Problems with the motherboard.

3. Memory problems.

4. Problems with external equipment.

First of all, unplug all the external devices and try to boot them to see if the host really starts, if it can start, there is a problem with the external devices, and then check them one by one.

Then, check whether each power connector is plugged in; Whether the CPU, memory, and graphics card are installed correctly.

Next, try it with a different memory module; Give it a try with a different graphics card.

If none of the above methods can be solved, it can be concluded that the motherboard is broken.

The graphics card doesn't turn when it's turned on, and the display doesn't.

Hello, I have seen your question and am sorting out the answer, please wait a while

Hello, I have seen your question and am sorting out the answer, please wait a while

You're talking about this because the console isn't really booting up, it's just powering up the field. There are several reasons for this phenomenon: 1. The problem of power supply.

2. Problems with the motherboard. 3. Memory problems. 4. Problems with external equipment.

First of all, Kaihan shouted, unplug all external devices, turn on and try to see if the host really starts, if it can start, there is a problem with the external devices, and then check them one by one. Then, check whether the old lap ports of each power supply are plugged in; Whether the CPU, memory, and graphics card are installed correctly. Next, try it with a different memory module; Give it a try with a different graphics card.

If none of the above methods can be solved, it can be concluded that the motherboard is broken.

I didn't see the specific computer configuration, but there are two possibilities, which are relatively large.

The first is that the graphics card is not compatible with today's computers. Although compatibility issues have been significantly reduced now, some specific platforms and graphics cards do still have compatibility issues, you can check them online.

The second is that the power supply of the computer is insufficient. The power consumption of graphics cards is generally large, and some graphics cards have large requirements for 12V power supply current, and if the power supply is insufficient, it may not be able to turn on normally, so you can try to change to a high-power power supply.

First of all, if you use your brain to install the discrete graphics card without any problem, it proves that there is no problem with the entire configuration hardware. Because you didn't see the new graphics card and the old graphics card needed power. There is also whether the power rating of your power supply is enough for your discrete graphics card.

Because some discrete graphics cards have high power consumption, they need to be connected to an external power socket. If you don't plug in these power outlets, it won't work properly, so it's a good idea to check if your power supply is big enough for your new graphics card. There is also the need for a new discrete graphics card to be connected to an external power supply, whether you plug it in or not.

If the graphics card is normal on other computers, it won't light up on this computer, and you need to replace the high-power power supply and try again, which may be caused by the power band not moving.

Take a closer look at whether your new graphics card needs to be powered independently, if you need it, you must plug in the power supply to be displayed, if it is plugged in or not lit, it means that your power supply is not enough to cause it, and the test is normal with a high-power power supply Then you have to change to a new power supply!

There are two problems, one is the compatibility of the graphics card, which your motherboard does not support, and the other is that your power supply is not enough to power the rated power it needs.

If this problem occurs, it is basically not a power supply problem, or a graphics card problem, you first change to a larger power supply, it may be that the old power supply is insufficient to cause the boot to be unable to start, try to change a larger power supply, it doesn't work, then your new graphics card may have a problem, change to another computer to try first.

This situation is caused by insufficient power supply, and it can be used normally by changing to a power supply with a higher power. After changing the graphics card, first check whether the power supply is enough, and remember to remember ......

If your computer changes to a new graphics card, the direction of the CPU will not turn for a while, then it is very likely that your computer's power supply will not rise, so there is no way to attack the power supply of the graphics card and the CPU at the same time, so they have no way to work together at all, and it is likely that your power supply is not enough at this time.

First of all, let's take a look at the specific model of the new graphics card, how much power, and whether the power supply belt can't move. The independent power connector on the graphics card is not connected to the power supply.

In this case, most of the power supply is not enough, the power consumption of the graphics card you change should be much larger than your original one, resulting in overload protection of the power supply load, and there is a new graphics card with an independent power interface, which may occur if you are not connected.

That should be that your computer configuration is too old, the graphics card is also old and can be adapted, and the new graphics card does not have the appropriate driver installed.

It is recommended that you go to the brand's official website and find the appropriate graphics card driver according to the system and model to install.

Of course, you can also use professional driver software to drive Life, Master Lu, etc., and directly check the installation of the appropriate graphics card driver.

If there is a POST showing that you can't enter the Windows interface, it is a resolution problem, the advanced security mode sets the resolution to the lowest, then restarts to enter the Windows interface, and then sets the resolution as needed;

2. If there is no self-test interface, it means that the CPU is not working at all and the computer is not starting. Check whether the motherboard battery and CPU are installed properly (it is possible that the replacement of the graphics card has touched the CPU);

It is most likely due to insufficient power supply, or an external power supply that is not properly connected.

Other possibilities:

1.The graphics card is in poor contact with the display signal cable, so you can reinstall it.

2.The monitor itself is faulty, and this one needs to be replaced.

The computer does not respond when it is turned on, make sure that there is no problem with the graphics card, and the CPU does not turn for a while, which should be the problem that your motherboard does not support this graphics card.

Actually rule out the problem of the graphics card, you have to consider the voltage of the power supply, the power of the graphics card is high and your power supply power is not enough, this situation will occur, try it with a higher power supply.

Fan Zhang graphics card,The computer doesn't respond when it starts.,Make sure the graphics card is okay.,The CPU will turn around.,Install it if you don't turn it for a while.,My old graphics card can be turned on normally again.,It means that this graphics card should probably not be worthy of the memory of your own computer.,That's why it's like this.。

If this situation occurs, it should be caused by the poor contact of your graphics card, because there is no problem with your graphics card, and it can only be caused by poor contact with the graphics card.

1.It may be a problem with the electrical power supply, please check whether the power socket is normal and whether the power cord is normal.

2.If you have a power supply problem with the case, please check whether there is a 5 volt standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the voltage, you can find a power supply to change it.

3.Motherboard problems, if both of the above are not problems, then the possibility of motherboard failure.
