Problems with new build, HELP!!!!
I am trying to upgrade with the following hardware
ASUS ROG X470 crosshair vii non wifi
32 GB Gskill F4-3200C16Q-32GTZRX
Ryzen 2700x CPU
ASUS Vega64 STRIX video card
Initially encountered problem with not being able to boot into the BIOS. Eventually I was able and made some changes, don't recall all that I made, but when I saved them the system would not boot back into the bios. After much agony I finally tried with 2 video cards installed and it will now boot into the bios. I am unable to boot into win10 reliably. Sometimes it gets as far as log in screen other times it shuts down before that point.
I have updated the bios 1201 which is the latest as far as can tell.
Any ideas an why I need 2 videos cards installed in order for it boot into the bios and why I can not boot into windows reliably?
