Question PC Won't POST, Pretty sure it's a CPU problem

So my system was a ryzen 1700, gtx 1070, corsair cx650, and corsair 16gb ram. I built this system a year or two ago and everything was working great.

A few weeks ago I accidentally spilled some liquid on it and that was one of the WORST mistakes of my life because I've been living in a nightmare ever since.

I did the best that I could to clean it up and salvage whatever I could. There wasn't too much liquid so it wasn't all bad...Or so I thought. Everything seemed to still be working until it started rebooting a few times and then ultimately didn't POST but would power on (with rgb lights on and fans spinning). Additionally, no inputs would work. No monitor signal, nor power to usb devices.

After some tests with another pc I had, I concluded that the motherboard was the issue. After purchasing a new mobo and installing it, things were looking the exact same as it was before. Additional testing made me almost confident that it was my cpu. So I bought a ryzen 2700x since I might as well upgrade in the process so at least there's something positive at the end of all this. After replacing my old cpu with the new one, IT WORKED! ...for a few minutes.

Once I figured out that it had worked I turned it off so that I could finally rest with peace of mind...nope. When I went to turn it on to use it, the same problem occured. No POST yet the pc powered on. I know that the problem is related to the cpu but could the psu be damaging the cpu? Any ideas? I'm desperate

Possibly a faulty PSU not outputting the correct voltage & current to the different hardware components if you have a spare PSU I would replace it and check if the same problem persists or use a multimeter to test that it's outputting the correct voltage/current.
 
The cx 650 is a lower tier psu i suspect it is the issue! i would not attempt to boot your pc without changing it for a good quality unit such as the corsair rm650 80 + gold, as components could be damaged by a dodgy psu.
The liquid damage screams danger and most likely the culprit
