Question New built PC takes about a 25-40s to post (read further)

[devilgodspider]

(please understand that I really mean 30-45s, this isn't me exaggerating.)

Description:

Computer is turned on, there is no display signal and no peripheral turns on (mouse and/or keyboard), after 30-45s the mouse&keyboard turn on their lights and the display goes from sleep to being active, after a few seconds the "ASUS" logo pops up and everything proceeds as normal. that's it, that's the description... I've never seen this before, please help

This is not a pre-built PC, it's a newly build PC with all parts being brand-new with only 1 exception being the Power Supply (of which I replaced with mine to check, and the problem mentioned on the title still occurred exactly the same way).


Specs:

CPU: Ryzen 7 7800X3D
Cooler: Lian Li Galahad 240
Motherboard: Asus Prime b650 Plus
RAM: G.SKILL Ripjaws S5 Series 2x32GB DDR5 6400MHz C32
GPU: Gigabyte RTX 3070 (3-fans model)
SSD: NVME Samsung 980 Pro 2TB
PSU: XFX 850W Core Edition
Case: Phanteks Eclipse P400

I can think of a couple of possibilities:
1. If your ram specs in the bios do not work, the motherboard will try to find a set of specs that work.
2. If you have some adapters that are unused there will be a delay while the motherboard waits to see if anything is there.
3. Some motherboards have a setting to test ram on startup.

Just to make the suspect list smaller it looks like the cpu has an igp.
Remove the gpu and connect to the mobo.

If no help use just one stick of ram.

If no help unplug the disk.

3. Some motherboards have a setting to test ram on startup.

1. RAM specs are working 100% checked in BIOS and in Windows (CPU-ID)
2. No adapters
3. Tried my best but couldn't find anything related to this on my Motherboard.

iGPU is disabled on BIOS, I tried all of the aforementioned above anyway and then turned iGPU back to disabled.
Still having the same issue...

Sorry for the delay as well, I had a lot going on at my work that put a stop for my personal time at home :')

Update of things I've tried doing:

-I tried checking all of my cables from the Power Supply to the rest of the system and everything is properly connected;
-I am not able to try a different CPU or RAM at this time, but I did find this:

B650E-F GAMING WIFI slow boot time with EXPO enabled

I hope this helps other people, I will be trying it soon and give you an update.

When building an AMD system, use RAM that's specifically EXPO and not XMP or XMP/EXPO as the XMP profile can cause these issues. I sold my G.SKILL Ripjaws S5 and replaced it with G.SKILL Flare X5 because of this very reason.

You were having issues with time until post because of your RAM? (making sure I understood correctly)
