Windows 10, on boot it init Keyboard + Mouse and delay is approx 3s, Looking to improve boot-time

Hi all,

I have been a system builder for many years and I cannot overcome something that appears to be new to me. for windows 10 at least!

with all W10 based systems I build for clients and myself.. AMD & Intel I notice that as soon as the system passes POST/BIOS and goes to load windows Both the KB+Mouse turn off for about 3 seconds then turn on again.

It appears the HDDs stop during this time and is a delay.. none the less My systems are fast to boot, and am happy with how fast they get to the OS.. but this is a little odd to me!
my systems that include this issue are
GB Gaming 5 AX370 / AMD Ryzen 5 1600 w/ SSD
GB z370 Gaming 7 / INTEL 8600K w/ SSD
GB z370 Gaming 7 / INTEL 8700K w/SSD
tried combination of different accessories.. from corsair mouse/keyboard / logitech / microsoft..

all of them are around 10sec or less to windows.. but the kb/mouse thing I cannot work out for the life of me..

I have tried many component configurations as well as many windows tweaks and cannot find a solution.

maybe this is just normal windows operation. ?!

Does anyone here have a clue on this topic?

Cheers
Shaun

I'm not sure what the dealy is.
What you describe sounds like the usb control handoff from the bios to the OS. Can you try disabling USB support for legacy devices in the bios and see if that changes things?
