ASUS ROG X570 Crosshair VIII Hero (Wi-Fi) Won't boot up after shut down.

I posted this in September of last year. I had a few replies back and forth to check this and that. Then the guy just stopped responding.
I still need to get this resolved. The problem is the same.
If I shut down the PC, or put it in sleep mode it will not restart without switching off power to the PSU. And when it does start up, it sits at the boot screen for 3 minutes before starting Windows. (I’ve timed it.) I can restart it and it is fine (23 seconds from the boot screen to the Windows login screen.) But to start from a shutdown requires a power off/on procedure.

I’ve found other instances of this same problem and no one has come up with a fix for it.

Please help if you are able. It is much appreciated.

Hello, @Bigfan3 

Due to the ongoing local holidays in our area, my response time may experience delays.
I apologize for any inconvenience the delayed replies may have caused.
Based on your description, the Q-CODE A2 on an AMD motherboard indicates "Boot up device abnormal".
Please refer to the corresponding steps in [Motherboard] Common Q-CODE (Error CODE) and Troubleshooting to attempt problem resolution.
Meanwhile, we suggest you refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.

Thank you.

Hello, @Bigfan3 

May I ask if the situation you described happened after any changes were made? For example, adjusting the BIOS setting or connecting an external device
What is your current BIOS version?
If you haven't updated to the latest BIOS 4702 released on November 1, 2023, please consider updating and clearing CMOS to reconfirm.
Regarding the situation you described, have you attempted cross-testing any hardware, such as the CPU or PSU?
When the issue of being unable to wake up/ power on occurs, are there any Q-LED indicator lights or Q-CODEs?

Thank you.

I didn't know there was a newer BIOS Version. I'll get it updated and see what that does.

There were no changes in hardware, no software. It was just out of the blue. I got up in up morning, came into my computer room, and tapped the space bar to wake it up and nothing happened. So, then I shut off the power then back on and it booted up in the manner described.  The BIOS is @ BIOS 4601 now.  I've cleared the CMOS several times.  The Q_LED Display -AA- as it runs right now.
I don;t know what you mean by  "cross-testing any hardware, such as the CPU or PSU" 
I provided a link to the original post but I'll copy/paste the first post here:

ASUS ROG X570 Crosshair VIII Hero (Wi-Fi)
Serial Number: N2M0KS085236B2J
Bios: 3904 X64, Build Date: 12/14/2021 (BIOS 4601 Now)

This is a fairly new build/upgrade. I've had it since February of this year. (2023) 
Up until about a month ago, it was fine. Great even.  But now,  after I shut it down, or put it in sleep mode, it will not boot up by pushing the start-up button on the AXT case, or the start button on the MB. I have to reach behind the case and shut off power at the PSU. Then turn it back on and It will restart just fine. (With either the Case Button or the MB button.) It's only when I put it in sleep mode or shut it down. 
And another problem that started happening when this start-up problem did. It takes almost 4 minutes to get fully booted up.
It sits at the "Press Delete or F2 to enter bios" screen, and after about 3 minutes it finally gets going. 
And it does this on a Boot from shut down, or sleep mode. Where it used to boot right up. 

I cleared the CMOS, then Updated the BIOS, and  I left all MB settings at Default.
It still took three minutes to the Windows login screen.
I tested it by putting it in sleep mode, I tapped the space bar and it came right up.
So, I shut it down, let it sit for a few minutes, pressed the start-up button on the front of the case, and it came up but it still took three minutes to get to the Windows screen. 
So, I tested it again, but this time, I was back to turning off the power before it would come up. And still takes 3 minutes of sitting at the "Press F2 or Delete to enter the BIOS" before it gets to the Windows login screen.
So, we are right back to where we started.

Also, I have a short video I took of the Q-LEDS, they flash different numbers and codes when it starts to boot up. Then as it's booting up it goes to A2 and stays there until it Boots to Windows Login Screen. (Three  Minutes)

Well, we solved the trouble.
It was an 8TB Seagate drive. I unplugged everything I didn't need to run. It came up in 30 seconds to the login screen. I started connecting peripherals one at a time. Shut it down, connect a drive, shut it down connect a drive and it was working fine until I plugged in the Seagate. When I plugged in the Seagate 8TB drive, it started taking 3 minutes to the login screen, again. Unplug the Seagate, we're back to 30 seconds to boot.

Thank You for the input!. 
I had forgotten this basic troubleshooting technique.
