Thanks, but meant also what is connected to the rear IO and front USB ports. Have you tried replicating this with minimal devices plugged into the system?

When it occurs it doesnt matter what I do, I cant get the rig to start properly until I clear CMOS.
Meaning I disconnect everything from the MB (intern & extern) but the system wont start.
I upgraded the UEFI to 1102, so far I had one week of no breakdown but I barely shutdown the system now.

Update 02/2019:
To get rid of this problem I found a workaround for my system.
First I did disable every "go to sleep mode" option in windows! It only shuts down sdds or monitors now, not the whole system as I run some VM's in the background anyway it doesnt hurt me much.
As an IT Administrator I did a big troubleshoot and disconnected everything that could interfere and yet I could replicate this problem sometimes. It is really weird but still I think it is an issue between nvidia bios and mb bios and api to the OS!
I didnt had this problem with my older card and this was the only change I made to the system back then.
Hope someone who stumbles into this thread can find some help with my response 😉
