Ask for help with a black screen, is it a problem with the monitor or the graphics card?

What is the boot animation? According to what you said, if it is turned on and the screen is black before it reaches the desktop, then the display is broken For LCD monitors, this kind of black screen is very common Where to buy it Take it back and repair it This kind of problem is very easy to repair (if it is within the warranty period) But after the warranty, it will be troublesome Very expensive - -

It won't be another problem, if it's a graphics card problem, it will not be displayed directly, or it can be displayed but it has been shaking, or it is not clear, and it will not be fixed to turn on the computer and it will be blacked out directly, and if the power indicator of the display is on, then it must be a problem with the screen, and the circuit board is good. However, the cost of the LCD monitor is on the screen, and it is in the warranty, and it is replaced free of charge

I was dizzy from upstairs

First of all, it is certain that the fault has nothing to do with the graphics card driver, if it is just a driver problem that will not flash and go black, at least the BIOS can be displayed normally. If you have the conditions, change the monitor first, and then change it together, including the display data cable industry, which is the probability of the display being faulty.

If it's not a display issue, you'll have to change the motherboard. Otherwise, buy a discrete graphics card. (The probability of graphics card failure is small, if it is a graphics card problem, it may only be an interface problem, if it is a chip problem, it is impossible to pass the COMS self-test).

The monitor screen is black, but the indicator light is normal (should be green or blue light), which means that the signal has been correctly transmitted to the monitor and has been received by the monitor;

This phenomenon indicates that there is a problem with the display and has nothing to do with the host computer, including the graphics card.

The problem of the graphics card can basically be solved by installing a system. Drivers are very likely.

Take the motherboard battery out and put it back in after 5 minutes Check whether the monitor cable is loose.

No diamond does not do porcelain work! Old notebook black screen? In the end, it's a matter of **.

Hello! According to your description, I estimate that there are problems in the following points, 1. The VGA cable connection behind the computer host or its own problem, operation method (1. Check whether the screws at the host end of the VGA port and the end of the display are tightened, and clean up the lower port 2. Check whether the needle of the VGA port is broken or skewed, if there is a need to replace the wire, 3. Connect the power on state line and shake the connection at both ends to see if the monitor has a response, if there are other VGA cables, you can swap them and try it).

2. If it is an independent graphics card, you can remove the graphics card and wipe it with an eraser or cloth, plug it in to see, if it is integrated, it will not be operated, it is recommended to go to the maintenance point to let people see.

3. If there is a problem with the two accessories of the high-voltage strip and the logic board, it is recommended to take it for warranty or repair.

But there is another possibility, that is, interference, this possibility is very small, high-power electrical appliances will start to operate will be black, you can rule out the try, unplug high-power appliances such as air conditioners and turn off the power Try it in the game, if there is no black screen, it is caused by interference The monitor is fine, if it is helpful to you, remember to adopt it.

**Whether the display is the phenomenon of a blurred screen;

If you are using a discrete graphics card, you can update the graphics card driver to see if it is normal;

If the graphics card driver is unstable or the power supply is insufficient, it is recommended not to use third-party software to install the graphics card driver;

Boot into safe mode to see if the screen is blurred, uninstall the previous graphics card driver in safe mode, and then reinstall it.

If the indicator light can still be on normally, it means that the display is still good, it should be a problem with the graphics card, thank you for adopting.

This is very similar to the problem of the monitor,You can try to connect the headphones or speakers,And then turn it on,If you hear the sound entering the system, then it must be a problem with the monitor。

See if there is a problem with the monitor power contact.

There is a high probability that the power supply is broken
