    Prime X370-Pro No boot/post or beeps

    At my wit's end here. Thought I would give AMD a try after almost 20 years and splurged on a new Ryzen build. Put everything together, hit the power button, no dice. Fans spin, pretty LEDs on the mobo light up; no video, no beeps, nothing. How I got here:

    1. Replaced PSU with known working spare.
    2. Cycled RAM in all slots.
    3. Pulled everything out of the case.
    4. Replaced the MOBO. (Exchange from retailer)
    5. Replaced the dang internal speaker.
    6. Checked CPU pins (repeatedly).
    7. Reseated CPU (repeatedly).
    8. Cried myself to sleep.
    9. Dreamt I found the answer and woke up depressed.
    10. Resorted to asking Reddit for help.
    11. Asking you fine people for help.

    System Configuration:

    Motherboard: Asus Prime X370-PRO
    CPU: AMD Ryzen 1800X
    Memory: Patriot Viper 16GB PC4-21300
    GPU: 2x(EVGA GTX 1080)
    PSU: Rosewill "Hive" 850w
    Cooler: Corsair H110i AIO

    My goal in troubleshooting has been to just get the thing to give me beep codes at least, so I have not installed the VGA or hard disks. Because the manual (yes..) specifies beep codes in the event of no memory found, I have concluded that the issue is not the RAM due to the fact that I still get no beeps even when no RAM is installed.

    I am left with the possibility of a defective retail CPU, which I have never actually seen happen, or maybe it has something to do with mounting pressure? (Saw a few threads about that.) Have I missed something?
