The computer screen turns black after turning on the computer. What's going on?

First of all, we determine what is the problem based on whether the light on the monitor is on or not.

The first situation: If the light is on and is blue or green, and the monitor screen is black, it means that the data has been transferred to the monitor but the monitor is damaged. When the monitor screen is black and the indicator light is normal, it is speculated that the backlight is not on due to the high voltage board not outputting. It is recommended to repair the high voltage board to solve the problem.

The second situation: The light is on but is yellow or red, indicating that no data is being transmitted, which may be caused by poor contact of the monitor data cable.

In addition, there are:

1. The computer motherboard cmos battery is dead.

Check whether the graphics card is installed correctly and make sure it is in good contact with the motherboard slot. At the same time, also check the contact between other boards (such as sound card, network card, video card) and the motherboard slot.

3. Caused by poor CPU contact.

4. Caused by poor contact of the memory module.

5. The computer is infected with a virus and the bios is destructively refreshed.

6. If the screen resolution does not match, you can first find a normal monitor and adjust your refresh rate to the lowest level, and then try to adjust it from the lowest level upwards. The display resolution of a computer is an indicator of how many pixels a computer monitor can display. First, you need to connect the computer's power cord, turn on the desktop computer, wait until the green startup light turns on, and then press CTRL ALT F7 to restore the default resolution. It can also be solved by changing the resolution of the computer after turning it on.
