P7P55D-E Red CPU LED (Very Minor Water Damage)

Computer boots up, but no display. The CPU led is a solid red.

I spilled a small amount of water on top of the tower and I think at most a few drops fell inside through the fan holes. It was running at the time and a few minutes later it powered down.

No visible damage to anything - I have it an hour or so while I unplugged everything and reassembled. Same result.

What are the possibilities here?

it'll take a lot longer than 1 hr to full dry out, leave it 24hrs, could it have made it all the way down to the psu?

Will give it 24hours before trying again.

Only evidence I found of water getting inside was a couple drops on the jagged blue metal frame around the CPU. Possible that some hit the PSU, but no way for me to be sure - dont see anything.

Gave it 24 hours, no dice.

How should I go about troubleshooting which part to purchase without having a display in this case?

Well the red led for the CPU is on so you can fairly safely determine the problem is with the CPU at the moment. I will suggest the following. First wait another 24hours (I recommend 24+ hours in a non-humid environment - up to 72 hours if humid in your area) then reset your CMOS. If nothing then, remove CPU and then reseat it - you will need to clean off and apply new thermal compound to the heatsink when you do that. If the red led remains on after that, I would think the CPU (could be motherboard though) would be in need of replacement
Hope it helps

you might need to clean the area where the water fell with iso propyl alcohol and a cotton bud, as there will be material left behind that was carried by the water.
