I have a I9
Rtx2080 water cooled
Msi ace z390
Ibuypower 750 or 1000 psu can't remember
Corsair water pump and ram

I Would get a lot of waue uncontrollable error blue screens and then I got critical process dead over and over. It won'tlet me reinstall os or restore PC or even bring it to a different time. Pulled the block all pins are good CPU shows no sign of damage so i re seated CPU with new paste... Now PC turns on but no displays. Shows 66 on the led error screen. I'm thinking the MB is dead because I notice a slight sag in the middle of the board. The whole thing sits on a test bence open case type.

A bench test should be done on a flat, firm even surface with a piece of cardboard that is larger than the MB placed atop of the surface, this prevents the MB from flexing and breaking the embedded printed circuits when connectors like the 24 and 8 pin power connectors are inserted, what you describe suggest that the board has indeed flexed and may have been damaged.
 
have you looked up that 66 error code in your mobo manual to see what it means?
did you also remove the GPU and RAM, clean their contacts and their mobo slots and see if that helps?
