Windows 10: LONG delay while booting

I don't THINK this is a Windows 10 thing, so...

ASUS X99 Deluxe, Windows 10 Pro, 32 GB memory, AMD 5700 XT graphics...

For the last couple months, when I boot the system is posts (presume post is that time when the system wants you to press DEL to go into the BIOS). Then it sits there for 80-90 seconds. Then it boots.

A bit more information. If I do a boot starting from having the power supply shut off (cold? boot), it SEEMS to boot fine. If I do a normal shutdown/restart while in Windows, it sits. If I hit the reset button it boots. What I've taken to doing is when I do a "normal" shutdown/restart, when the "press DEL" screen shows up I hit the reset button, and it boots fine - no extremely long delay while it sits there...

It displays a 99 while sitting. ASUS says this means Super IO Initialization. I've read a bunch of discussions various places and they all have "THE FIX", which, of course, haven't worked...

One discussion insisted if you get this code the motherboard is bad and should be replaced. I don't think so, since it only happens when doing the shutdown/restart from Windows.

One discussion indicated it was a motherboard connections - pulled all the plugs, reconnected, reseated the memory, made no difference. The other day I removed all the hard drives except the O/S SSD and it still did it. Put them back in 1 by 1, no difference.

Another discussion said to replace all the SATA cables to the hard drives. So I did that. Nothing. No change.

I replaced the graphics card - not because of this, just because it needed it... No difference.

I've got 2 monitors, 1 DP, 1 HDMI. Removed the HDMI one, no difference.

I think I'm out of IO things to unplug.

Ideas?

Extremely long and incomplete boot

This may be a long shot. My PC hung at boot yesterday after typing the password - see Can't Login - Further Troubleshooting Steps?

I ran chkdsk c: /spotfix and all is now fine. Someone has also suggested running chkdsk c: /r.

 

Long sleep delay?
