Super Long BIOS Boot on ASUS B350 Prime Plus?

I'm quite confused. My boot times are pretty awful. When I check task manager, I see Last BIOS time: 22.8 seconds.
Once the Windows logo appears, it boots in 5 seconds. It's getting to that screen that takes forever. Even shutting down the computer can take a long time.

It's a fresh install on Windows 10 on my SSD. Completely new build. I've tried turning off everything in startup as well as in the BIOS and fast boot is enabled. I'm not sure why it's taking so long.

I have a Samsung 850 EVO SSD in two other computers. Computers that are nowhere as powerful as this one. And they boot twice as fast.

Any ideas what I can do to fix this? Or what may be causing the problem? This also happens if I run stock speeds.

Build:
Ryzen 1700x at 3.8ghz (still testing the overclocking)
ASUS B350 Prime Plus
Corsair Vengeance LPX 16gb DDR4-3000 (running at 2666)
Cooler Master Hyper 212 EVO
Samsung 850 EVO 500gb SSD
Seagate Barracuda 2TB HDD
EVGA GTX 1060 6gb
EVGA SuperNOVA G2 550 watt
Fractal Define R4
Windows 10

The SSD is the bootdisk.
The only SATA driver is RAID, which I don't need. I have all the other drivers and they are up-to-date.

I have not mapped any network drives.

I have read that it may be related to the RAM, or the BIOS checking the RAM, but I'm not sure how to fix this or turn it off.

sounds like the bios is having issues with a component in your system. I'd start by checking for a bios update/moptherboard drivers. If still a problem, try removing all but one stick of ram (if more than one), and try it in different dimms, rebooting each time. Repeat for a second stick. A difference in boot times would reveal a culprit stick of ram. If you have onboard video, remove the GPU and boot without. Make sure your SSD is on a sata3 port that isn't shared with other devices, and not a slower sata 2 port. Try a different sata cable.

Hopefully one of those suggestions gets your boot times down.

Hi all. I've got similar problem, but my long loading time caused by double load - i see splash screen twice. And some SMIBIOS version 2.0.0 between 2 loads. Any suggestions about it? I realize that this is somehow connected to my nvme ssd, but i want to get rid of this double loading

I had the same problem with exact same mobo. I figured it out though. I had my SSD with windows connected to SATA port number 4 on the motherboard, while the DVD-ROM and other HDD's were on SATA 1, 2 and 3.
I looked in my motherboard manual to see how the SATA ports are numbered, and connected my DVD-ROM to SATA no.1 port and changed my SSD to SATA no.2 port. The rest of the HDD's to SATA 3 and 4. This fixed my loong boot time from 2 minutes to 8 seconds instantly.
I'm pretty sure you have the same issue. Oh, and after doing this, make sure you have the SSD as the first boot priority in BIOS (alternatively, you can put the DVD-ROM 1st and SSD 2nd).
