(Nov 25) Boot Failure with history

PowerSpec G355 Gaming Desktop PC
Windows 10 Pro, Ver. 21H2 (OS Build 19044.2251)

Howdy Folks

Recent History:
Nov 12: "Checking SSD Primary after Scan & Repair Warning (for Peace-of-Mind)"
Checking SSD Primary after Scan & Repair Warning (for Peace-of-Mind)
Running SFC /scannow "found corrupt files and successfully repaired them".
I installed Hard Disk Sentinel which is now telling me my SSD & HDD are all good.
-
Nov 18: "The VGA card is not supported by UEFI driver"
The VGA card is not supported by UEFI driver
Nov 24: With help from @Ghot I updated my BIOS version and all seemed good.
-
Nov 25: This morning this desktop failed to boot from last night's 'shut down': I had lights and fans, but nothing else.
A hard shut down was my only option, producing the same results. Ditto: 2 more times and the next time it booted properly.
First thing: I performed a 'Restart' and it booted properly with a fresh new OS.
I then ran a SFC /scannow and found no problems there.
-
I'm seeking recommendations on what I can try next to isolate an unknown issue.
TIA to all who read this post and to those who reply.

What type of cable are you using for vid card to monitor? Is it... old?

HDMI
Maybe ~4 yrs old.
Am pretty sure it's okay; e.g. earlier issues gave me a full screen warning, like the one attached here (Note this warning is NOT current)
Cable is tight.
&FWIW: Machine doesn't "see" keyboard or mouse

Hello @jdUnionngarden,

Are there ANY Yellow Triangles in Device Manager ?

Howdy Paul,
Good question, answer is "No".
I expanded all.
Thanks,

Did you perform a Clean Install or simply select "Restart" from the menu?
Are you able to run ---dism /online /cleanup-image /restorehealth ---followed by ---sfc /scannow ---and continue with sfc until a clean report is given ?

@joeandmarg0
1. I restarted from the menu so I would have a newly booted OS.
2. I'm sure I can run that command, but first I would have to research what it is and what it would do.
I'll take a look at it in the morning.
Thank you.

Howdy joeandmarg0,
All looks good up to "/ScanHealth" and another "sfc /scannow". (Attached below)
Do you see any reason to also run "/restorehealth"?
Thanks for introducing me to this function.

Fast start may be more part of a problem than part of a solution. As you have a SSD, Fast start is useless.
Is Fast start enabled?

Howdy @Megahertz
You may be right; I tried turning it off (a while back) and found boot time was pretty much unchanged, *but* "shutdown" took considerably longer. (NBD, except I don't like walking away until the process is complete.) I didn't bother trying to find out why; do you have any thoughts on that?

If nothing else comes along (here), I'll turn off Fast Start again and see what happens.
Thanks,
