So about a week ago water spilled down the top vent on my PC. I did a pretty <language> job at responding properly and now have a non-functioning PC and I dont know how to find out a proper fix or which component(s) need replaced or attended to.

I know water went into the top vent and I heard it hit the fan, and I know some also dripped down the back end down the motherboard usb slots and connectors at the back.

I didnt get it disconnected from power very quickly, and stupidly tried to power it back up pretty soon after it got wet.

After that I let it dry for 2 days with no luck, and then again about 4 days later I tried again yet to with no success. (At times I took out the GPU and power supply but that's all of the disassembling I did and the case was open the whole time) The first attempt to reboot the day of, the machine would power on for a few seconds, lose power and quiet down, then boot up and crash again. At the 2 day and 4 day attempts to boot, it would boot, quit, then boot again and stay on until I turned it off

It'll boot up and run after the failure, but I get no response from my monitors. I've tried an older graphics card that I know isnt broken and that didnt work, and the 2 cards have different connectors (newer one is displayport to HDMI, older was DVI) so it seems safe to say that the issue isnt the cards themselves or <language> up cords because water got down the back. The monitors are functioning properly too as I've tried them with other devices.

When I try to boot the system it LOOKS like it's functioning properly. The GPU fan spins so it's at least getting some power.

My only guess is that it could be the power supply, in that maybe it was damaged so not ENOUGH power is getting to the whole system hence the constantly failed first attempt to boot? and maybe the GPU isnt getting enough power and causing the lack of monitor response? Idk if that theory even makes sense. My only other guess would be that the motherboard somehow got messed up.

Just a warning, I'm so far from an expert with this stuff. This is a PC I built but someone basically walked me through it, and besides upgrading GPU's I havent done much since it was built 4.5 years ago and a lot of this stuff is over my head. Before the water incident it was running well.

Any clue how I could try to find and solve the issue? I'd really appreciate the help

Try breadboarding which is you unplug your hardware then put it in one by one until you boot fine. That can eliminate things which will make it easier to narrow the problem. But from what I can tell, I think you borked your mobo >__<
