I've been building my first PC for about 8 years, so I'm rusty. It's a 3600 with a B450 board (Asrock Fatality B450 Gaming-ITX), powered by a modular 650W PSU.
I've installed the CPU and its AIO cooler, the RAM, and plugged in the mobo and CPU power connector along with the front panel power switch and power light headers. When I switch the machine on, the front panel illuminates, so power is clearly getting to the mobo. After about 30 seconds, the front panel light goes off, the little LED in the AIO pump flashes briefly, the AIO fan (connected to the CPU fan header) spins, and then the front panel illuminates again. This cycle just repeats constantly. The mobo has no power LED or a built-in speaker for POST, and I don't have a spare speaker to connect, so I can't immediately tell what the issue is. I've reseated the RAM and ensured the power connectors are fully in, but the problem persists.
My initial thoughts are that the mobo BIOS hasn't been updated to support zen 2. Amazon specifically told me the boards were good to go out of the box, but I'm not sure I believe that. Is that a possibility? I really don't want to think that I've fried the mobo, especially as I've been paranoid about ESD. Interestingly, if the CPU power connector ISN'T attached, the whole AIO LED/fan spinning thing doesn't happen.
