Likely, your motherboard is shot.
You can connect your monitor to your motherboard and/or your graphics card.
What is a "shot" motherboard?
The monitor only has DVI and another kind of port that looks like HDMI
but one side is square, not clipped.
Only the graphics card has those
ports. The computer itself doesn't.
I could buy a DVI to usb, or DVI to VGA cable and see if that resolves
the issue, if it is the graphics card that's going bad.

No, you need a new motherboard,
one that accepts M.2 NVMe memory cards.

That would be DisplayPort.

You really don't have much of a clue, do you?
When I turn one of my computers on, the video output is sometimes not
there, and sometimes is. Computer always boots up normally, making the introductory sound of windows coming up, etc. But it is exactly like
there's no monitor attached. It's not the cable or monitor. That much
I've tested.
And on some other occasions the screen appears normally when I turn the computer on, and if I keep turning the computer off and then on screen
always appears. On occasions that it won't come up, no matter how many
times I turn the computer off and on, screen won't come up.
What could it be? Bios? Graphics card? The round 3 volt button battery?
The electronics on MB itself? Anything like that anybody here
experienced? This is the first for me. It can't be virus cause that
computer is hermetically isolated from internet.
I tested the battery, it is still at least 3 volts. Should it be 5 volts?

Def sounds hardware related. But maybe not.

Strange about it is that when it happens, farther turning it off and on
does not work. I have to come to the computer next day, then it would sometime work no matter how many time I turn it off and on. A heating
problem perhaps, requiring hours to cool? Or a charge accumulation
somewhere requiring several hours to dissipate? I've never had this
problem before.
Two years back it once acted like this but just for one occasion. Then
never happened till some 10 days back and this time it has kind of
stayed like that.

Ok, I think I have found a pattern. Every time when I'm done and turn
the computer off _and_ turn the electricity off to the entire set
(computer, monitor, speakers, surge protector), 24 hours later the
system will turn on normally after I connect the electricity to the
system. But, now I'm pretty sure, when I leave the electricity to the
system on after turning the computer off, then 24 hours later the video signals to the monitor is absent after turning the computer on.
By now, I have conducted multiple tests on both scenarios mentioned
above, carefully observing the behavior.
So definitely something accumulates either heat or charge when
electricity stays connected to the turned off system. What could that be?

I actually have a similar problem with my Zephyrus G14 laptop. There's a fingerprint sensor on it and the hardware will fail in certain
circumstances. If the connector is already attached to the laptop and I
plug the unit to the power plug, it will short the sensor. No fiddling
around in the Device Manager will do anything to restore functionality,
and I have to disable the sensor in the BIOS, then re-enable it and
restart. However, if I plug the power adapter first and plug the
connector to the unit after, everything works as expected.
