The screen remains black after the computer boots up

I've encountered this situation,I was the machine ash removal that time,CPU was not plugged in when the machine was installed,That's the case,Fire me for half an hour,Yesterday the computer was normal,It is recommended that you unplug all the host hardware again,It should be OK,Note that there is a small gate knife that fixes the CPU when plugging in the CPU,Generally, when the fan is pulled, the CPU will come out,Plug it back and forget。

If your machine is an assembly machine, and it does not involve a warranty and can operate it yourself, it is recommended to re-insert and unplug the memory, check the gold finger of the memory, or see if there is dust in the chassis, clean up the dust, you must be a problem with the motherboard or memory or graphics card, the CPU should be fine in general!

The picture tube is broken, it is recommended to buy a new TV from the new, because the repair of the picture tube is not worth it, and you can buy a new one with some money!! Hope it helps! Then it should be a problem with the graphics card, it is recommended to unplug the graphics card and wipe it on the line!

You're a problem with the system! It is recommended that you reinstall the system!

..Kinescope?

You reseat your graphics card and memory.

It will definitely be good.

The display is good.

How many lines of memory? It is possible that one of them is broken.

Can the graphics card be replaced?

There is also the motherboard, see if there is a capacitor bulge or if there are any traces of burning.

CPUs generally don't break.

The reasons why the computer screen is black when the computer is turned on and the solutions are as follows:

1. If there is a problem with the computer memory, the computer should be sent to a computer repair shop for repair.

2. If the computer graphics card is full of dust and the graphics card is in poor contact with the computer main chassis, the computer graphics card should be removed and the dust of the graphics card should be cleaned with a brush.

3. The interface between the main computer case and the power supply is loose, resulting in poor contact between the interface and the power cable, resulting in a black screen of the computer, and a new interface should be given to the computer.

4. The external power supply of Yanxin is insufficient, resulting in some old displays or some displays with high power consumption cannot be started normally, and new monitors should be replaced.

5. The failure of the display switch circuit is also the cause of the black screen failure of the display wheel, such as the damage of the power switch or the internal short circuit, and the professional should be asked to repair the display switch circuit.
