Computer black screen, blue screen, fancy screen.

Analysis of common faults of computer blurred screen, black screen and blue screen

A computer black screen

Common solutions:

1 if you have been in use, in order to replace the hardware, the black screen is mostly caused by memory problems, reseat the memory bar, clean the memory slot dust and gold finger, you can generally recover (plug and unplug the memory after releasing static electricity to avoid damage to the motherboard caused by static electricity)

2 change the power supply to cause the black screen, check whether the voltage and current of the power supply meet the output power

Second computer blue screen

Common solutions:

1 you can take a look at the blue screen code of Baidu, which is not listed here.

See Annex 1

2 enter PE mode or safe mode and test whether the hardware is faulty or not

3 recall what you have done before, whether you have installed any drivers, the maladaptation of the drivers will also cause the blue screen.

It is not common to encounter the situation of computer screen.

See annex 2

1 whether there is a problem with the monitor itself

2 whether the video card and power supply are loose

3 install the wrong driver

There is a problem with the power supply (I have been looking for this for a long time, but the test is that there is a problem with the power supply and the power supply is unstable).
