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 😉
