In short, everything was working just fine. I unplugged all three case fans to see if CPU fan was being loud. CPU fan was quit, so I shut down, and reconnected all 3 case fans and it never turned back on, no beep, nada.

Motherboard: GIGABYTE Z97-HD3
RAM: 16GB corsair
PSU: ANTEC BP550 plus
OK I have to admit, I vape an e cig in front of this computer for a couple years. I never thought
anything of it, but a few months ago stumbled on a thread about it but there were no damages mentioned, someone was basically just questioning and warning.
I've air duster cleaned inside the PC and the case fans about 5 times since building it. 4 days ago I cleaned everything very well. There was a good amount of dust and cat hair on the dust guard and fans.
I used tissues and made everything as clean as possible. There was a noticeable gel on the fans from the e cig (vegetable glycerin vapor), and some of the dust was gel. I cleaned everything and it has been running perfectly fine for the last 4 days but the 3 case fans were still quite loud. I'm not sure if they were always this loud because they came stock with a low budget Rosewill case. I have quite a bit of dust/cat hair so I figured the fans needed to be replaced because I couldn't clean inside the actual motors (would rather purchase new fans than dissect and possibly need to crack the case fans open).
So tonight, I decided to run the PC for a few minutes with all the case fans disconnected to hear if
the CPU heat sink fan was also loud and needing replacement (stock cheap intel cooling fan and heat sink). It's winter and quite cold in the home. I turned the PC on after disconnecting the fans and went on youtube for about 3 mins and the PC was quiet so I concluded I'll just buy case fans and not also a new CPU fan for now.
Then I reconnected the 3 case fans.
PC won't turn on.
I'm thinking maybe the PSU fried. I'm pretty sure that usually even when the PC is Off, the prong for the internet cable is light up in back of the PC but it's not now. I though it also has a light on the
motherboard that's always on but I don't see a bulb. So anyway, I was thinking it's no big deal at this point. I open the case and think maybe something came loose. Snugged all the connections but it won't turn on again.
Then I disconnected every single component (there's no PCI cards, I'm using the intel's integrated
GPU). The only thing I forgot to disconnect was the RAM. I disconnected RAMs and reconnected them at the end after disconnecting and reconnecting every single wire and component (except I didn't remove the CPU from the socket of course [or should I?].
The bezel on this case is quite rough to open but the power button seems undisturbed (it's sealed, not going to crack it open as a slim chance that it broke when opening the bezel - I think the internet cable end should be light up regardless if power is being supplied.
There's no clicky power button on the motherboard and I'm not about to use a paperclip to try and jump start it.
Then I checked the PSU in case it had a safety trip/switch but I found nothing. I was going to open the PSU to see if it had an internal one but then googled on my phone that it had a 3 year warranty that I'm still under and I didn't want to remove the "warranty-voided" sticker over the screw to open the PSU. I doubt they'd put a trip switch inside the PSU anyway.
I checked power from multiple outlets. Nothing.
I have to admit I did the first half of all of this while wearing fleece pants which are quite staticy.
Like, they make my leg hairs stick out I randomly noticed earlier today. But I mean, how easy is it to really fry a computer with static granted that I'm not like rubbing a balloon and touching the CPU?
I'm hoping it's just the PSU for some reason. If so, can you recommend me a new one to buy on ebay that also has 550W? Then I will sell the Antec if they send me a warranty replacement instead of a refund.
Thank you so much if you can solve this!
UPDATE: just did the paper clip test for the PSU and the PSU worked. Ok so maybe it's the mobo. I will google how to diagnose that. Given the chain of events, what/how mobo is related? Also I need ASAP a replacement mobo if that's what's bad. please suggestions. I am looking to possibly upgrade this whole system but not RIGHT NOW, so I just need anything as good as the mobo I already have. I'm hesitant to buy the exact one even though I'll probably get another one free under warranty but I'l sell it.
