After plugging in the new graphics card and turning it on, the monitor has been black, and there is

If the console is still working, it's a problem with the graphics card, because my machine is like this, you just turn the monitor off and on again. When you enter the desktop, there will be no black screen.

It's just a problem that solves the black screen.,I don't know why it's the root problem.,It seems to be a driver problem.

The power of the power supply is insufficient. It is best to use a 400W power supply with a DX10 graphics card The rated power of a 300W power supply is also 250W, in fact, 250W and 300W are the same, and 300W is just the peak.

If the 250W power supply is poor, the power rating will be even lower.

So if you use the current 8600 or HD3600 or above graphics card, it is best to use a 400W power supply

250WMS is not enough with HD 3650, right?

At least 300W power supply is required, you say that the card has an external 6pin power interface. It's not that you can use it if you connect it, for example, you can connect the 8800GTX.

Gold finger or power supply problems.

Power supply, graphics card, memory, these 3 you have to check If you are sure that there is no problem, then the estimated motherboard is burned.

The power of the power supply is a bit low, and it is best to match it with a 300W one, but I am afraid that the power supply cannot be brought up

The reasons for the failure of this question are as follows:

1. If the display is faulty, press the switch of the display to observe whether there is a flash of silver. Conditionally replace the display under it.

2. There is a problem with the display data cable, if you have a spare cable, you can replace it and try it.

3. The graphics card is set beyond the range of the display, and as soon as the computer is turned on, press the F8 key If there is an interface display, then it is the original collapse cause.

Common fault 1: When the computer is first turned on, the screen of the monitor shakes very much, and sometimes even the icons and text cannot be seen clearly, but it will return to normal after a minute or two.

This phenomenon mostly occurs in wet weather, which is caused by moisture inside the display. To solve this problem completely, you can use the moisture-proof sand from the food packaging to string it with cotton thread, then open the back cover of the monitor and hang the moisture-proof sand near the tube socket at the end of the CRT neck. In this way, even in wet weather, the above "problems" will not occur again.

Common fault two: after the computer is turned on, the monitor only hears its sound and does not see its painting, it is pitch black, and the picture can only appear after dozens of minutes, which is caused by the leakage of the picture tube base, and the tube seat must be replaced. When the back cover is removed, you can see a small circuit board at the end of the picture tube, and the tube socket is soldered to the circuit board.

Carefully unplug the board, solder the header, go to the electronics store and buy the same header, and solder the header back to the board. At this time, do not rush to put the circuit board back, first find a small piece of sandpaper, and carefully wipe the pins protruding from the end of the picture tube with sandpaper. In particular, pay attention to the oxide layer on the pins, if you don't wipe it cleanly, it will soon become old**.

Put the board back in and you're done.

Common fault 3: There are always lingering interference clutter or lines on the display screen, and there are also annoying noises in the speaker, which is mostly caused by the poor anti-interference of the power supply. If you are too lazy to do it, you can replace it with a new power supply.

If you have enough hands-on ability, you can also try to replace the filter capacitor in the power supply yourself, which often works; If the effect is not obvious, you can replace the switch tube together.

Common fault 4: Gray screen of display.

This problem is mostly caused by the graphics card. If it's a new graphics card, it's probably that the card is of poor quality or incompatible, and then there's that the correct drivers haven't been installed. If the video memory is added to the old card, it may be caused by the difference between the newly added video memory and the original video memory model.

Common fault 5: The display screen is black.

If there is no signal transmitted to the monitor due to a damaged graphics card or a disconnected monitor, the monitor's indicator light will flash incessantly to indicate that no signal has been received. If the resolution is set too high, the maximum resolution of the display will also appear black, and the display will be destroyed, but the current display has a protection function, and it will be automatically protected when the resolution exceeds the set value. In addition, hardware collisions can also cause black screens.

What should I do if the monitor screen goes black after the computer is turned on.

The coms of the motherboard is cleared, which is to unplug the battery on the motherboard and wait for 5 seconds before pressing.

If it still doesn't work, clean the graphics card slot on the motherboard.

If you can, you can take another graphics card and install it on your motherboard.

See if there's something wrong with your discrete graphics card.

What is the output interface of your graphics card?,VGA port、DVI port?,If the VGA port output has no image,It is recommended to find a DVI to VGA cable,It may be that the VGA output module is broken,I have encountered this situation before,Under normal circumstances,If the graphics card fan turns,The graphics card is not broken。

It is very easy to judge whether the hardware or software is wrong when the boot is not displayed, and the host can be turned off by pressing the boot button short, which means that the memory and CPU detection have passed, and the graphics card has not passed. If it doesn't show that you need to press and hold the power button to turn off as soon as you turn it on, 80% of it may be a memory module, just plug and replace the memory. Nowadays, there are very few problems with the CPU of the computer.

So the CPU doesn't have to worry about him. However, the probability of problems with the graphics card is getting bigger and bigger, and there is a momentum of more than the memory, and now the problems of the graphics card are big, I don't know whether it is hardware or software, many of them are just individual compatible driver software versions of the problem is regarded as hardware failure, I can often find completely normal use of computer accessories in a friend who is engaged in maintenance.

You use the integrated graphics card and the machine is fine. It means that your machine is normal except for the independent display, and the rest is the problem of your independent display, under normal circumstances, the graphics card is not plugged in, and you try to insert the graphics card after the position of the active graphics card, try to boot it, it really doesn't work, just change it, there is no repair value.

If you exclude the situation that the graphics card is plugged in, it means that the graphics card is broken.

But it's not that easy to break, plug it in more, clean up the slot, and try more.

The graphics card is unplugged, and the pins are wiped off. Plug it back in.

It's very simple, the graphics card is broken, take it and check it!

There may be a problem with your graphics card GPU.

What computer monitor? Laptop or desktop???

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.

Corrupted graphics card: The new graphics card may be damaged in transit, resulting in boot failure.

If this happens, you can try the following:

install the graphics driver;

Check if the power supply is sufficient;

Check if the graphics card is compatible with the motherboard;

Replace the graphics card that is as good as new.

If you still can't solve the problem, we recommend that you seek help from a computer professional.
