So, your monitor is missing an image. The first thing to do is to make sure that the problem is not a software problem, that is, it is not a failure of the video drivers in the operating system. To do this, simply restart the computer, and if it shows data from the motherboard, simply reinstall the OS, after connecting the hard drive to another PC and copying the data.
If this did not happen, the case may be both in the monitor itself and in the video card and motherboard, very rarely the reason is RAM, without which no image will appear on the screen either. So, our task is to determine in which component the problem is. This can be done by alternately replacing them or rearranging them to another computer.
Monitor
It rarely breaks down so that the image immediately disappears. Most often it's a cable, so if you have an extra VGA, DVI, or HDMI cable handy, be sure to use it. If it's not about the cable, return the monitor under warranty (if it's not over yet).
Video card
When using active cooling, overclocking, insufficient ventilation in the case, some models of video cards may fail. If this is the case, it will often be seen by the swollen condenser. If the image disappears after trying to overclock, then you need to return everything to the factory settings and, after turning on, monitor the temperature.
Motherboard
Both the PCI slot itself and the graphics chip can break if you use it. In the first case, you can try to rearrange the video card to another connector, and in the second case, buy an external one. True, this is only suitable as a temporary measure. In other cases, you need to hand it over for repair or under warranty.
