PC not going into post

So, my fan was making some noise because of some dust so I cleaned it with a can of compressed air, I sprayed into the front fan and a little over my GPU. Later I found out that the can I was using has water mixed with air inside of it. There was not actual sprays of water coming out of the can it was more like wet/moist air.

To test if the fan was making a sound also I turned my off multiple times by pressing the button on my power supply.

When I tried to boot my PC after that it didn't work. All my fans spin like they do usually but that's about it. My motherboard does not show doctor debug numbers and my monitor recognizes the connection but does not receive any input.

I tried disconnecting my front fan because that might have caused a short circuit but that did not help.

Is my motherboard causing the problem? Or maybe my CPU or GPU? What parts of my PC should I replace?

Thanks in advance.

EDIT:
I have had this pc for about 2.5 years and no problems with it.
I tried to clear cmos but it did not help

wait... so you just flip the switch on the back of your psu on and off? over and over? im guessing you fried your board..

Have you tried clearing the cmos? :v

(someone please make a gif of have you tried turning it of and on again but with cmos <3)

Pretty much. Not like spamming it tho. So did that just affect my motherboard? Or can it affect other parts too?

And yes I did clear cmos.

your best bet is to try to clear the cmos on your motherboard. if not you might of fried something, you should never flip the switch off on the back of your psu while your computer is still on.

was it working prior or is this a new build with all brand new components?

No. I have had this PC for about 2.5 years no problems with it.

Just asking since it's very common to get a DOA board out of the box. Do you know how to "clear" your BIOS?

Try this. Turn PC off then PSU off. Disconnect cable from PSU and then hold power on (on the PC case for 30 seconds). Then connect power cable to PSU and turn PSU on and try PC power on button.

Do what @mistarz has suggested, if that doesn't work.
Try reseating the Graphics card and memory.

I did both of those things. Didn't help.

any visible water damage? maybe just unplug all the power from it and put a fan in front of it for like a day

@thechickenman sorry Sir but I think you fried something. PSU or else. I would start with taking PSU out and troubleshooting. Also suggest not to troubleshoot on whole PC since if PSU failed you might be damaging more hardware.

So you think the PSU failed? Because all the fans seem to get power. I'd rather think its the motherboard. Anyway. How would I troubleshoot without a PSU?

Sadly it seems that your motherboard is fried.

To check your power supply:
Grab a multimeter and set it to 20 volts.
Put the black probe into any molex plug on a black wire.
Put the red probe into the yellow wire.
It should read 12 volts.
Red wire is 5 volts.
Next test the 24 pin plug. If you unplug it you will have to jump the black and green wire (makes it think you hit the power button)
orange is 3 volts
blue is negative 12 volts. (black probe on blue wire, red probe on black wire)
If those are right, your power supply is probably fine.

If that passes, when you turn on your computer it should beep (unless it never has because of failed wiring or cheap manufacturing). If there is no beep, it is probably your motherboard.

I would add one thing - sometimes (rarely) all voltages are ok but PSU does not send "power good" signal and motherboard does not start. Grey wire should be +5 VDC. Details below
