I am still experiencing some problems with booting Windows on my newly built PC. I think is is likely a driver or Windows configuration problem but will include HW info anyway.Here is my parts list: PCPartPicker Part List
I previously had a problem with Windows booting at all but think that has been solved. This current problem has completely different symptoms but could be somehow related. See the other thread here for background. https://pcpartpicker.com/forums/topic/340952-help-with-unreliable-windows-boot-on-new-build

Now to the current very puzzling issue. Windows is showing a very predictable (but unusual) boot issue. It seems to have two modes of operation.
Mode 1: If booted from UEFI screen, or restarted from within Windows or is the first boot after using a different boot source, the display screen stays dark / blank. In other words, this mode happens on a "Normal Boot" only. After 60 seconds, I can press the power button momentarily and the screen lights up with the Login Screen immediately. At that point everything works as expected.
Mode 2: if booted with "Fast Startup Boot" active, the system boots immediately and very reliably to the login screen. Everything works as expected. (Hybrid sleep / shutdown is in effect.)
The difference seems to be that a Fast Boot always works, whereas a normal slow boot always results in a black display. After waiting for 60+ seconds, a momentary press of the power button brings up the login screen and everything then works as expected.
I have UEFI set to boot on Fast mode except following a failure where normal startup is set.
I have done a clean boot (disabling all 3rd party drivers and processes) and the behavior is the same.
I have enabled the boot logging in Windows and the log looks mostly normal although there are references to "Not Loaded: dxgkrnl.sys" in the log. This is shown several times in the boot log.
I have looked for errors in the windows system logs and only found errors related to the Intel WiFi driver failing with a 5 GHz signal. My local Home WiFi uses only 2.4 GHz, so I disabled the 5 GHz in the WiFi driver and now no issues are reported in the system log during boot. It is clean.
The symptoms of a 60 second delay before any pressing the power button sounds like a HW timeout during boot but with nothing being flagged, I am at a loss as to what might be timing out.
Prior to the 60 second period, pressing the power button momentarily does nothing. It almost seems like Windows is waiting for something an gives up then somehow goes to sleep waiting for a power button press. It is not actually sleeping, however. Pressing keys on the keyboard has no effect -- only pressing the power button. In addition, the system is not actually sleeping as power usage is unchanged (measured at the power cord) and all fans, lighting and other functions are active.
My only guess so far has been an error or timeout in the display driver. However, the MSI Updater says the driver is the latest available. In fact all other drivers have been checked and are said to be latest / correct version.
Any ideas for what to check next? The system works fine and the PC runs like a Formula One Race Car. While it can boot windows every time now, it is annoying that this timeout happens when I need to use a "Normal Slow Startup" boot such as after a Windows Update Restart.
