My computer went black for a moment after it turned on10

Check to see if your computer is virus-in, or if your data cable is not connected properly.

The reasons why the screen suddenly goes black for a while after the computer starts up are as follows:

Display issues.

If there is a problem with the monitor, you must first confirm whether the monitor is broken, and you can turn on the power of the monitor separately to see if it is normal. (If conditions permit, connect the monitor to another host and try) If it doesn't work, then the monitor is broken, change the monitor.

Problems with the monitor cable.

The chance of damage to the monitor cable is very small, and you can check whether the cable is loose or in poor contact.

Problems with memory modules.

Memory module problems often occur, including: the memory module is dirty or the gold finger is oxidized, you can use the eraser to wipe the memory stick, especially the gold finger part, the gold finger on both sides should be wiped.

Static electricity appears on the motherboard.

Power off the main unit, then find this coin cell battery on the motherboard and take it out and leave it for a minute. Then put it back in and turn it on.

Discrete graphics card issues.

If you have a built-in graphics card on your motherboard, remove the discrete graphics card first, then connect the display cable to the motherboard's built-in graphics card, and try to boot it.

4.Power issues: If you're having trouble with the power supply**, it can cause your computer to not have enough power to boot up, or it may have a black screen. Check that the power cord and power supply are connected correctly, or replace it with a new one.
