A build up of silent annoyance with the occasional huffing, and redoing whatever it is as many times as I need.
But if it gets to the point where I'm getting so frustrated that I'm just making even more mistakes, then I put the game on pause and walk away to do something else. Return to it when I'm calmer. Sometimes I'll look up guides if I feel like I'm not gonna get it.
As a kid, I pretty much did the same thing (I still have my PS1, it still works. I'm in my 30s now, lol. It's almost as old as me.) Except instead of walking away to do something else, I'd pester my older bro to "fix it" for me lol. And then he'd proceed to tell me that I screwed myself with my set up and there was no way he could fix it for me, that I'd have to start all the way over from the beginning! And so, I learnt to take a breather.
