Hi, I just build pc with this specs:
Amd athlon 200ge
ASRock a320m HDV R 4.0
Panther sad 120gb
4gb ram
I connected it to the vga cable, turned it on and it worked normally. I downloaded the vga driver from the official ASRock site, and it worked normally, I turned it on and off a few times to see how it works and everything worked normally. I used the computer for about 3-4 hours and turned it off. After half an hour I turned it on and the windows loaded and the image from the monitor disappeared after 3 seconds. I unplugged the cable and plugged it in again, the image was on the monitor for about 3 seconds and disappeared again. I turned off the computer and turned it on and the same thing happened. I unplugged the cable from the monitor and from the computer and turned on the monitor without any contact with the computer and again the image showed 3 seconds and disappeared, I know it's not a problem in the computer because I tested the monitor only with the power cable without the vga cable and it was the same thing again. Please answer me what to do, I need help

Usually if a monitor doesn't have a signal, it will go on black. It may or may not give a message with "no signal".

The monitor's logo just shows when it's turned on and it should mean the monitor is working.
- Have you double checked the cable is plugged in correctly?
-Have you messed arround with the buttons under the monitor? Is it possible you changed the monitor input from VGA to HDMI or anything and that's why it's not working?
-Do you have another monitor / TV? If yes, have you tried connecting that one?
- Do you have a videocard in your computer? If yes, where's your VGA cable plugged into? (Videocard/ motherboard).

Otherwise, if you have a different monitor / tv, connect it and try uninstalling the VGA drivers and see if that solves the issue.

That makes me wonder, have you considered trying another power cable for your monitor or trying a different wall socket? I'm not sure if that's the proper word so I hope you get me :)
