For what it's worth, when I purchased a desktop PC last year, I had to return 3 before I got one which wasn't problematic. Two of one model both shut off randomly, the first of the 2nd model had a bad hard drive (write failures while installing arch). On the other hand, I had two 2018 Intel MBPs fail in the span of 4 days last month. Just my personal work computer. I set up 2 new MBPs in 1 week. Don't know the cause but after a while they would stop starting up properly. I ended up with an M1. I speculate it's all related to covid shortages somehow but who knows.
