Please disconnect the graphic card and connect the monitor to onboard HDMI port and check whether the display can post normally.
Could you provide photo showing the debug code as there's no C1 error can be look up in debug code table.

If you have a video, you can upload it on imgur.com or Youtube and link to it.

Did you take a look at the pins of the CPU socket? If any of them are bent (which can easily happen), you can have all kinds of problems.

Take out the CPU and carefully inspect it and the socket for any bent pins, foreign objects, or any abnormalities. Check very carefully (with a magnifying glass, if possible) if all the pins look exactly the same, in position and in height.

If the pins are all perfectly aligned, you can put the CPU back in. For further testing, you can put the cooler back on without replacing the heatpaste. Finally, how to do it properly once it all works: Clean the CPU heatspreader and the cooler base, because when you re-use old heatpaste, there can be trapped air bubbles which could lead to overheating. So i'd then clean it 100% and then apply new heatpaste. I use soft, lint-free paper towels and q-tips dipped in high-purity isopropanol alcohol to clean, and then apply a drop of new heatpaste onto the middle of the CPU, at least the size of a large grain of rice. It will be spread by the cooler pressure.

It did post once so I dought the pins are bent plus I was extremely careful
It's a watercooled system so it's hard to get to stuff (hardline glass tube) but I'm guessing I will have to take it apart soon I'm running out of things I can do without disassembly

No.

Try taking out the M.2 SSD. If that fails, try additionally with just one RAM module in slot A2.
I'll give it a shot and let you know
Probably will not get to it for a week though going out of town and have to remove gpu to get to both m.2 sticks
