Good news: my system is no longer power cycling; I exchanged my motherboard for one that has the ryzen 3000 ready sticker.
Bad news: I can't get it to output video. I trying clearing the bios, and was able to get into the UEFI briefly. I then restarted so I could boot from USB and...nothing again. I tried clearing the bios again but I was never able to get the UEFI to show up after that first time. I tried it out with both one and two sticks of memory.
I'm pretty much ready to throw in the towel and take it in for professional analysis. Does anyone have an idea of something obvious I might be missing?
Motherboard is Asrock fatality b450 itx, processor is 3600, PSU is brand new SF600.
15 days on MB's and CPU's. I'd imagine they'd test them if asked. If your still in the return window it's probably your best bet.
They do testing, but it's a $40 charge. At least that's what the Fairfax location told me. But it sounds like each location is run differently, so you'd probably want to check with yours about their costs.
