Randomly when I boot I get the first ROG screen then a hang (30 seconds) with qcode 40. Then I get the Rog screens and the machine boots and I get a check disc which I let run and then Win 10 boots normally. If the machine boots with no hang I do not get the check disc at startup.

I have run AS-SSD and Crystal Disk Mark as well as Magician and the SSD's all report 100% health. The only odd occurance i have seen is after I switched to the corsair ram due to the D15 if I try to run XMP instead of automatic in the Bios the Corsair ram does not like it and I got BSOD's which I tracked down to memory. I have done a fresh reinstall of windows and all drivers as well. Other than that I am running AI Suite 3 V1.01.56 for the Xpert fan control, EVGA Precision X 6.1.6 for the GPU and Aura V1.04.29

I am looking for possible causes and things to try before buying ram to swap since I have to pull the MoBo to swap it due to the D15 cooler. Specs below

Bios ver: 0906
GeForce Driver: 384.76

Thanks
