If the monitor and video card are firmly installed, please try another monitor that is confirmed to be normal.If the screen is no longer black, the reason is that the display may be damaged.3、 Confirm whether there is a problem with the fan. If the display is not damaged, further check whether the cpu fan is running.If it is running, use a multimeter to measure whether the voltage output is normal to ± 12v, ± 15v. If it is abnormal, change a power supply for a try.4、 Check the CPU, video card and memory module. If the screen is still black, remove all components except the CPU, video card and memory module, and then power up the computer.If there is a memory failure, there should be an alarm sound.If it is not due to the memory, please replace it with a normal CPU and start the machine for re detection.If the black screen still appears, only one motherboard can be replaced, and the problem should also occur on the motherboard.
