Hello everyone,

I just got the Z270 Gaming K6 motherboard to replace an Asus Code IX that died, overall I'm pretty satisfied with the motherboard but I have this weird problem that occurs on cold boot after the PC has been off for a considerable amount of time (overnight while I sleep). When I turn on the PC the system starts posting but hangs for a minute or so with code 99 and eventually it boots normally, no need to restart or power off, after that if I shut it down and turn it on, it boots with no problems and really fast (10-15 seconds to desktop). Any ideas what could be happening?

Specs
CPU: i7 7700K OC yo 5.1 GHz
Cooler: AIO Thermaltake Water 3.0
Motherboard: Fatal1ty Z270 Gaming K6
RAM: Corsair Vengeance 16GB 3000 MHz XMP Profile
GPU: 2x Nvidia GTX 1080Ti Founder's Edition
Drives: 6 SATA3 Drives (3 HDDs and 3 SSDs), 1 Samsung NVMe drive 512 GB.

Thanks,
