Why does my Xbox One not turn on and how can I fix it?

So the new Fortnite chapter came out and my little brother was playing it when suddenly the console just turned off completely. I was able to turn it back on and try to play another but within the loading screen it turned off once more. So then I waited a bit thinking the Xbox possibly had overheated. After waiting about 10 minutes or so I turned it back on, signed in and had it sit in the Home Screen to see if the problem was trying to run a game or not but after about being on for just a mere minute, it turned off again. Let me be clear that it didn’t make the typical noise when it turns off usually and this has nothing to do with the outlet because everything else stayed on and my other consoles would work just fine. Now this time when I went to turn the Xbox One back on it would make the beep noise for it to turn on but nothing would happen. The Xbox wouldn’t turn on. I’ve tried unplugging it and giving it time, I’ve cleaned it, even disassembled it to really clean the dust and what not and I handled it with care and all and it still wouldn’t turn on. My questions are why is this happening, can it be fixed, and is there anything I can do to get it fixed? I’ve had this Xbox One since 2015 when Madden 16 came out so I’ve had it for roughly 7-8 years now and throughout all this time I’ve had it, I’ve never had an issue with it so you can imagine how surprised I was when it didn’t want to turn back on.

Hoping someone reaches out soon. Thank you.
