Hi,
I'm noticing a strange issue on my Z390I motherboard, where occasionally on boot I have a totally black screen - no signal detected. Usually (but not always) killing the power and performing a "cold boot" brings back the video signal. It will ALWAYS do it when I restart through windows. I don't believe this is a GPU Driver issue, as a "Blank screen boot" will not even show the bios splash screen, - so pre Windows loads fine, as I can hear system sounds, and RDP too the machine.
I know the first thought here will be "It's the GPU", but I had this issue previously, and blamed it on my Strix Vega 64. I swapped it out for my one of the trusty GTX980s from my other rig and the problem seemed to go away, but is back. I find it suspicious that exactly the same issue would manifest itself twice in the same way. To make life extra difficult, both of my rigs feature hard pipe water cooling, - so swapping GPUS is a major job! I don't believe it's a PSU issue either - everything is logged as stable. I run three monitors, I've swapped ports, I've disabled fast boot, run the windows DISM repair (again, black screen at post... I don't think it is driver related). Also running the latest Bios 2603. I can't boot in safe mode for a full DDU safe mode driver uninstall as the screen is blank if rebooted...
I've been googling this morning, - it looks like Windows 10 blank screen issues are by no means uncommon... but I can't escape the fact that it is blank at post.. BEFORE drivers have anything to do with it. Possibly UEFI related?
