My new pc turned off after a 12 uptime.

This is kind of really annoying and I've been super frustrated but I've already returned 2 different pc prio to this.

First pc, a cyberpower thatI had issues with no bluetooth device showing up at all so I instantly returned it within 2 ish days.

2nd pc was an omen, had high hopes after more than 6 days, until the usb and Bluetooth all disconnected all st once every 30 min to an hour....

NOW. The third pc.another try with cyberpower..had it up for 12 hours and it abruptly turned off while I was on it and won't turn back on.

Wtf do I do?? I'm losing faith in all best buy builds. I went up to check the reviews for these pc and others had the same problems as I am but like what are the fucking odds that all the pc I've got these exact problem???

On the other hand though, I did figure out what the problem with the first pc is because the 3rd pc had the same problem until I updated the Realtek driver I found on their page because I was so tired of refunding and swapping. I was really hoping this is the 3rd times charm. I'm so tired of this shit. There is a 60 day refund window but the fucking pc can't even last 60 days.

I'm so depressed, I've been bothering my dad to drive me back and forth to return these things and it's actually taking a toll on us because my dad doesn't have time for this. My parent finally allowed me to get a nice gaming computer and it's been the worse experience ever 🥲

What do I do now. Do I keep returning another pc and then what if I still get a bogus piece of junk. I can't build one myself, my parents are against it and I'm not very good at reasoning or persuading them. They also had a very valid reason because they told me if I get a pre-built like this, and it has issue I can still return it, but if I built one myself and it has issue I'm gonna spend more time and money dealing with it. Advice please!!

Edit: I also need help, I have my password tied to my microsoft account and it sync it to edge!! I could change password for the other stuff but like that over 500 login to places! How tf do I wipe everything if I can't even turn it on aaaaahhhhh

Also to note these are all Brande new pc, not open boxed at all, but they were on sale....
