The graphics card does not light up, and the screen does not light up when the graphics card is plug

Once you've eliminated any software issues (e.g. drivers), you're dead on your graphics card.

Is there a graphics card driver installed?

It's not strange to scrap it, because the graphics card you bought is second-hand, GF4 graphics card, it was a product of five years ago, and it has been out of production for four or five years, how to say that it is also an old product, you don't still think that the graphics card you got is a new product that has just been produced, right? Occasionally it can be lit doesn't mean anything, countless GF4 graphics cards with broken 3D chips, let alone lit, as long as you don't play 3D-related games, you can even run almost nothing all the time. That's what my colleague's GF4 graphics card was like that...

If it is true ... The statement on the third floor is really true.

Also, if your computer can still turn on, it just can't pass the self-test. This one is a bit of a headache. Because there are many reasons for this situation, one is a system problem, which can only be reinstalled, and the other is a bit troublesome, because there is a problem with the motherboard, and there is no way to do this except to change the hardware.

The third is that the graphics card on the second floor is scrapped. Even graphics cards that don't have a brand can't be touched at all, and their performance is shoddy, so they have to make a big discount on the basis of the original model. The current GF4 graphics card, the price in the second-hand market is quite cheap, **There is a brand on the Internet, it is only fifty or sixty yuan, within 100 yuan, you can buy a pretty good brand.

Personally, I suggest that you remove your graphics card, put it on another machine to run, and run it with the famous 3DMark20001 or 3DMark2003, and it can run normally, and there is no blur screen or crash on the way, which means that there is no problem with your graphics card, otherwise, it is 90% that your graphics card is broken.

If your graphics card can pass the above test, then you have to suspect that there is something wrong with your motherboard.

The light of the motherboard is on, the ASUS A88XME motherboard, it has not been used for too long, the gold finger has been wiped, and the display still does not light up after rebooting.

If there is no problem, it is a problem with the graphics card, or a problem with the capacitance of the motherboard.

You can unplug the memory bureau and wipe it, blow it and put it back on, and the graphics card is unplugged and wiped in the middle of the sleepy to try again, if it doesn't work, you can only find a professional inspection in Wang Lashan.

How to solve the problem of motherboard capacitance, the graphics card is colorful 760k, there is no need for independent power supply, and the fan is also turning.

It's not the power supply of the graphics card, it's the power supply of the display, and the graphics card may also have problems with the motherboard's contact with the motherboard.

That's why I told you to wipe the memory module first, and then the plug on the graphics card.

Excluding the power supply problem and connection cable problem of your display with dry power, that is, your motherboard training failure problem, capacitor or that contact point is broken, you can only find professional maintenance.

Summary. Hello dear, the graphics card does not light up: 1. If there is no compatibility between the motherboard and the graphics card, as long as the interface is the same, it can be lit.

2. Check whether the signal cable of the display is connected to the output interface of the graphics card, and if it is connected correctly, replace a cable with a little bit of ***. 3. It may also be caused by poor contact between the graphics card and the motherboard, and the gold finger part should be completely in contact with the PCI slot of the motherboard when the graphics card is reinserted and unplugged. 4. The display signal source should be switched correctly, and some monitors have an auto icon in the lower right corner, you click it.

5. If the graphics card has an auxiliary power supply cable, it is recommended to use some good quality brand power supplies as much as possible. If the above methods are checked and still can't be lit, it is recommended to contact the seller to check the graphics card.

This was good before.

Have you seen if there's something wrong with the monitor motherboard?

If you turn it on, you can see that the fan of the graphics card is rotating, but the screen is not lit.

Yes, there is a problem with the motherboard inside the screen.

When the host starts, you can use the side to serve the base.,It can be turned on before.,But the screen has had a flower screen phenomenon.,After the flower screen phenomenon, you can't open it anymore.。

So should I go to the screen and not to the graphics card or the motherboard? So what are the reasons that may cause damage to the motherboard inside the screen? Or is it because of the lack of power supply or the power supply aisle burned the motherboard inside?

You have no problem with the graphics card in this case.

Burnout is most likely.

It's most likely that the display burns out, but the graphics card is fine, you mean? Then I'm just going to change the monitor?

This English prompt is: Please turn off the computer, and then plug in the auxiliary power supply of the graphics card after landslide.

That is to say, this graphics card has a large power consumption and the bridge has disadvantages, and it needs to be plugged in to the auxiliary power supply before it can work normally (the power supply line is found from the host power supply).

The prompt on the screen is that the power supply line of the graphics card is not connected, and the backup car can be turned on to check whether the independent power supply line on the graphics card is connected or whether it is plugged in tightly.

If the computer won't turn on after plugging in the graphics card, it may be caused by the following reasons:

Graphics card driver issues: Newly inserted graphics cards may need to install the corresponding drivers, if not installed, it may cause boot failure.

The graphics card is not compatible with the motherboard: The new graphics card may not be compatible with the motherboard, which may also cause the boot to fail.
