my new rig is an 8700k with 32gb ram tridentz 3200mhz and 2 nve 500gb ssd running ubuntu 18.10.
I updated the bios to the latest version and worked well
I enabled the onboard graphics as I am not running discrete as I use the machine for development.
Was trying to set up the ram to 3200mhz (board recognized as 2600) in the bios.

Rebooted and now I have a black screen. All fans are working and memory lights up but no video output and no post (numlock off). Tried removing ram and resetting CMOS (power off, remove battery, push reset cmos at back a gazillion times). Nothing works... 
Do I need a new mobo? Any other suggestions?
Customer support had me try 5 cmos button push then said return the motherboard......
