Question PC doesn't turn on

[Jadepanths]

Hi. It's black Friday and I decided to build my first pc. Then, I got everything ran for a couple days. I noticed that on cinebench r20, my ryzen 7 2700x was running slower than the 1700x. Then, the real problems begin. My computer shutdowned and wouldn't turn on unless I unplugged it. Sometimes after unplugging, it booted, sometimes it didn't. So I tried swapping rams and even remove the battery on mb and put it back on. It still didn't solve the issue. Then, I decided to reassemble it. It turned on for couple times. Then it ran into the same issue. The last, time i tried to turn it on, it just went to a blue screen and doesn't boot since then even after unplugging the psu doesn't help. (When the psu is on, the mb's rgb light is also on) Any suggestion or thought for what is the cause? So I can order a new part to replace it.

Sounds like the issue might be with the PSU. What PSU did you get?
