Question Error code "00" - - - motherboard has power but there's no POST ?

[TheManOfMilk]

Hey!

First off sorry, this is my first time making a post like this so it may be a bit rough.

Specs:
CPU: Ryzen 9 3900X
GPU: AORUS GeForce RTX 2080 Super, waterforce WB 8G
MOBO: Asus ROG X570 Crosshair VIII Formula
RAM: 64GB Trident Z Dual Channel (4x16GB)
PSU: Corsair RM850x
SSD: 2x WD Blue 2TB SATA 3
Cooling: Custom soft tube liquid cooling, two PrimoChill 360mm radiators (three intake fans, three exhaust fans). Hydro X Series XC9 CPU Water Block, Corsair Hydro X Series XD5 Pump/Res combo.
May be missing something I can't remember.

I built this computer about 3 years ago and have been using the snot out of it on and off since then. Do semi-regular maintenance on all the components and cooling system. Used it in various "higher stress" ways from modeling/3D printing to servers, but nothing crazy.

Recently moved cross country with the system fully built and supported the GPU with some blocks. When setting it up in my place my father was removing the blocks and from my best guess accidentally loosened a connection of the coolant system. When we finally turned the PC on and the pump built pressure the line came out and got a fair amount of distilled water inside. Shut the computer off and dabbed up most of what I could find, let it sit for about 24hrs before fixing the line and refilling.

PC ran fine as I was topping up the reservoir, let it run for a bit to bleed the system. During the bleed, I was hooking up the peripherals the computer shut off. Tried rebooting again and it fired up, displayed code "00" and then shut off. It no longer boots but the MOBO lights up with power supplied to it. I've tried various lower-level checks to no avail, not very good at diagnosing PCs so I'm looking for any help/tips you may have. From all the random posts I've worked through that had similar but not the exact same situation, it seems to be pointing at the MOBO as bad. I wanted to be sure there isn't anything else I could do, or another cause of the fault, before pulling the trigger.

Sorry if there were any excessive details, I've just started work as an Auto Tech and I always try to get as much detail as possible when diagnosing. Still in the middle of moving so I do not have all of my computer stuff, and will be away from the tower for a few days.

One of the following, or all of them are dead: CPU, MoBo, RAM, GPU, PSU.
Since these 5 are needed for POST.

So, make note where the liquid spilled.

It was in the lower half of the computer, a little on the GPU but most of it went below. The PSU passed the paperclip check, the wiring was all dry with proper resistance levels. Mainly waiting to get my other computer from home to start part swap testing most of the components to narrow down the list.
Thank you for your note!

That's only way to test what survived and what didn't.

The PSU passed the paperclip check

Paperclip test doesn't tell if PSU is fine.

Doing paperclip test is like turning the car engine on and once engine starts, immediately assuming the car drives fine, without actually doing the test drive.
Paperclip test only turns PSU on, but it won't put any load on PSU. Hence why it's a poor "test" to do.

Yeah I'm aware it's not a definitive test, but it's just about the only thing I'm able to do with the equipment I have at hand. My previous comment may have been misleading with that statement.
