New M/B-CPU refuses to boot

[MR ZenWiz]

Update:

Good news.  I though that maybe the drivers in the 20.04 release might
just be too old for this new combo, so I pulled down 21.10 and
installed it (painlessly).

It boots fairly nicely and most everything is running smoothly.

Except:  the video driver it is running only goes up to HD res, not
2K.  I'll start a new thread for that one.

Thank you all so very much.  It's a huge relief to have my main
desktop back in working order.

Best wishes,

Mark
