Is this a MSI m/board? The one I found online is an AMD, which would mean New CPU, New RAM also. I have an MSI laptop, works well . Yes the Asus Prime Z390A is old by today’s standard, but up until now I have not had any problems with it. If I found another new one I could just use my existing CPU and RAM and start saving for a new build in 6 or so months.
Yep! However it stopped working in the ON position. Switch to OFF and try again.
When I switched from INTEL to AMD, some components were not quite as optimal. I sold them and arrived with an optimized solution.

Thank you karlmistelberger.
I turned the MEMOK! button to the OFF position and then tried to reboot.
Result was the same no POST, no beeps, no graphics, monitor says “No Signal”.
Was there anything special, procedure-wise, that I should have done? As in clear CMOS or such?
When rebooting always make sure the system is powered down entirely. Unplug the power cord and wait for several seconds before plugging it in again. Clear CMOS by removing the battery and following painstakingly the procedure given in the user manual.
The PRIME Z390-A has several onboard switches requiring special attention.
Earlier boards using the Z87 and the Z170 chipsets when ageing stopped working but recovered upon disassembling, cleaning the components and reassembling everything.
Thank you karlmistelberger.
I have gone through everything once again.
Nothing seems to be making any difference.
The results are the same no POST, no beeps, no graphics, monitor says “No Signal” and CPU fan runs for 10 seconds and then turns off.
I am going to start looking for a replacement board.
I saw one of your post, you have extra machine in the house. If one of those machine is compatible with your hardware in that problematic machine, you can try to test the hardware like the gpu, ram, or maybe the cpu. Don’t forget to wire yourself with grounding wire to avoid static. Me I built my own long grounding wire and I attach it to the house main ground wire in the basement for safety measure when working with the machine.
