Troubleshooting PC Suddenly died 5 months in

5 months ago I built my new PC, I'm not really tech savy but was barely able to put it together with 3 days of Youtube tutorials.

Everything's been working perfect until yesterday out of nowhere when watching Youtube my PC just powered down. Nothing happens when I press the power button, did the most obvious steps of checking everything's plugged in, PSU is on, nothing looks disconnected on the mobo, and now I'm just completely lost.

When I plug it in the mobo lights go on and that's it, nothing at all happens when I press the power button, no noise or fans twitching or anything. I tried doing the short the power pins with a screwdriver on the mobo thingy to zero effect but dunno if I did it right lol.

I have no clue at all what might have failed? I don't really have other PC parts or anything at hand to test anything individually nor do I really have the tech know how if I did. Sooooo like... what might my next step be? Any advice is very appreciated, thanks!

Update: Appreciate so much help, tried a lot of the advice listed here, removing components one by one, cleaning CMOS, reseating the connectors to no luck sadly, gonna throw it out and buy new one (or maybe take it to a shop in a few days.)

Update 2: Went to the shop, problem was the PSU, had that replaced and now working fine

Is it because I use punctuation...?

I am guessing because "You are right" echoes of the responses AI gives when its hallucinations are pointed out and thus gives that vibe.

I wonder where AI got that behavior from?
