The computer has a new graphics card, and it crashes after half an hour of booting, and it can t be

Because there are many configurations of the computer, the first thing is to do a check, it is OK before the graphics card is not replaced, then start from the graphics card and the motherboard, the graphics card first confirm whether the contact is normal, whether the auxiliary power supply line is connected, if the graphics card driver is installed, the graphics card can be placed on other computers to try, see if it is the same, the graphics card core is bad will also cause this situation;

Whether the motherboard has upgraded the BIOS, the early BIOS does not support the best graphics card, the chip and technology are not up to UEFI, you can turn off the desktop glass effect to try;

Power supply, as long as the independent graphics card is above the game level, the power supply required is more than 400W, and the power consumption requirements of the high-end graphics card have also increased.

The motherboard is upgraded to BIOS, and the power supply reaches the rated power, and the reason can basically be confirmed.

Take it to repair, it is estimated that it is not compatible, hold your computer, and install experiments on site.

When it comes to the slow computer and can't run large games, everyone thinks it's good to change the graphics card.

I don't know that there are many conditions for changing graphics cards. The first is whether the power supply is enough, and the second is whether the power supply to the graphics card on the motherboard is enough.

I came across a graphics card change a few days ago that burned the CPU. It took two days to think that it was a CPU problem, and after replacing the U, the problem of changing a large power supply was solved. But the south bridge of the main board is still very hot, forming internal injuries.

See that the order of your inspection is correct, and the replacement parts elimination method will solve it.

If the graphics card is not in good contact or incompatible, it will restart, and if the graphics card driver is incompatible, it will also fail, please follow the following methods to troubleshoot.

The following table describes common faults for graphics cards.

1) Poor contact fault of graphics card:

Poor contact of the graphics card usually causes faults such as failure to turn on and alarm sound, or system instability and crash. The main causes of poor contact of the graphics card are oxidation of the gold finger of the graphics card, dust, poor quality of the graphics card, or problems with the chassis bezel. For the poor contact caused by the oxidation of the gold finger, you can use an eraser to wipe the gold finger to solve it; For poor contact caused by dust, it can generally be solved after removing dust; For the poor contact caused by hardware quality, it is usually detected by the replacement method, and the replacement of the graphics card is generally used to solve the problem; For poor contact caused by chassis bezel problems, usually the graphics card cannot be fully inserted into the graphics card slot, and you can replace the chassis to eliminate it.

2) Compatibility issues:

Compatibility failures usually cause the computer to fail to turn on with an alarm, the system is unstable and crashes, or the screen is abnormally noisy. Graphics card compatibility failures generally occur after the computer is installed or upgraded, and are more common when the motherboard and the graphics card are incompatible or the motherboard slot and the graphics card gold finger cannot be fully contacted. Graphics card compatibility failures are usually detected by the replacement method, and the fault is usually troubled by replacing the graphics card.

3) Graphics card components are damaged and faulty

Damage to graphics card components usually causes the computer to fail to boot, the system is unstable, crashes, and the screen is blurred. Damage to graphics card components generally includes damage to the graphics card chip, graphics card BIOS, video memory, graphics card capacitor or MOSFET. For graphics card component damage faults, it is generally necessary to carefully measure each signal in the graphics card circuit to judge the damaged components, and replace the damaged components after finding them.

4) Graphics card overheating failure:

Since the graphics card chip will generate a lot of heat when working, it needs to have better heat dissipation conditions, and if the cooling fan is damaged, it will cause the graphics card to overheat and not work properly. Graphics card overheating faults usually cause system instability, crashes, and screen blurs. If the graphics card overheats, just replace the cooling fan.

The visual inspection of the graphics card is not firmly plugged in, resulting in poor contact of the gold finger circuit.

Your motherboard supports the graphics card slot: PCI-E standard.

The newly installed graphics card is a PCI Express x16 graphics card that supports backward compatibility.

This means that the graphics card and motherboard are compatible.

1. Plug in the original graphics card and try to turn it on, the purpose is to check whether the motherboard is burned out 2. If you can turn on the computer as above, it means that the new graphics card is not installed well, check whether the power supply of the graphics card is fully plugged in.

Make sure that the computer is good before changing the graphics card.

Replace the original graphics card and see if the computer is good, if it does, it means that there is something wrong with your new graphics card.

If it is not easy to use, it means that you have encountered other hardware during installation, resulting in the inability to turn on.

Solution, go to after-sales, first check that the power supply is powered on, and then reinstall the memory, boot to see the result.

That often can't turn on, it's not good. You'd better switch back!

What happens if I can't turn it on?

It should be installed**There is a problem, try to reinstall it.

Did you plug in the socket of the integrated graphics card, but changed it to the independent below.

Power supply issues? The power supply is not enough, what is the picture if you can't turn on the machine?

1. Poor contact.

2. The power supply cable of the graphics card is not properly connected.

3. There is a problem with the graphics card slot of the motherboard.

4. The power supply is insufficient.

Method: 1. Reseat the graphics card.

2. Check whether the graphics card has a power supply interface and whether it has been connected.

3. Clean the graphics card slot first and try again.

4. Replace the power supply of more than 300 watts for testing.

5. Disconnect the power supply, remove the button battery on the motherboard, and the same goes for the memory module--plug in the power supply, install the button battery--turn on again--force shutdown--disconnect the power supply--plug in the memory, turn on again, and (Does your graphics card have an external power interface?) If there is, it must be plugged in).

You can go into safe mode. Uninstall the original graphics card driver, start it again, and reinstall the new graphics card driver!

This may need to upgrade the motherboard BIOS, G41 is the boss after all!

Also, check whether the original power supply of your computer is enough, and whether the graphics card is plugged in with an external power supply!

The graphics card is not plugged into a power supply.

Either the power supply is insufficient and the graphics card cannot be supplied.

The computer can't turn on after changing the graphics card, there are the following possibilities, you can find the root of the problem first and then solve the problem:

1. It may be that the power supply cable of the graphics card is connected incorrectly. Nowadays, mainstream graphics cards need independent power supply, if the interface of independent power supply is plugged incorrectly, it cannot be turned on, it is recommended to check whether the wiring is correct according to the motherboard manual or graphics card manual.

2. The power supply is seriously insufficient, resulting in the machine being unable to run stably, so there will be a phenomenon that the machine cannot be turned on, and the high-power power supply needs to be replaced to solve this problem.

3. The graphics card itself is faulty, resulting in the inability to boot, at this time, the graphics card can only be replaced.

4. If you can't judge the reason why you can't turn on the machine, it is recommended to send it to after-sales service or find a professional for testing.

The purpose of the graphics card is to convert the display information required by the computer system into a driver, and provide a line scan signal to the display, control the correct display of the display, is an important component to connect the monitor and the motherboard of the personal computer, and is one of the important devices of "man-machine dialogue".

If there is no display at boot, this kind of failure is usually due to 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 a long and two short beeps after booting (for Award BIOS).

Video card, graphics card, also known as graphics card, is one of the most basic configuration and most important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics.

The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed. For people who are engaged in professional graphic design, graphics cards are very important. The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia).

Today's TOP500 computers all contain graphics card computing cores. In scientific computing, graphics cards are referred to as display accelerator cards.
