Zenith II Extreme Alpha Restart Problem

[PMokover]

I’m having a minor but annoying problem on one of my PCs. Zenith II Extreme Alpha motherboard, AMD Threadripper 3970x, latest update of Windows 10 Pro, latest BIOS.

When I restart the PC either manually or after a software update it does not fully restart. The restart process begins normally but at the point where it would normally start-up again, it just sits there. Power is on but it just sits there. However, at that point, if I press the reset button on the case it does restart.

Any ideas on what might be causing this or what I can do to fix it? Thanks.
