I have the following components

R9 5950x : Teamgroup ARGB ddr4 3600 cl14 ram 64 gigs over four sticks : Teamgroup Z440 2tb : Two teamgroup A440 4tb : Teamgroup a440 2tb : Gigabyte x570s Aero G : MSI RX6900xt : Seasonic platinum 850 : Arctic aRGB 360 rad :

Alternate parts on hand i have troubleshoot with... R7 3700x : 32gb of G-skill 3200 cl16 ram : GTX1080 : GTX1660TI : Second Aero G mob's : Seasonic Focus gold 550 : Samsung 970evo 500gig :

Now, onto the problem...

I fully assembled the system, and cannot get either aero g motherboard to recognize a cpu and boot.

Both mobos, with both available cpu's will click, flash the red cpu light, and immediately turn off.

They do this regardless of which power supply, which video card, which ram, which hard drive is plugged into them.

They are both revision 1 boards, both have been q-flashed successfully to F3 in the hopes that would fix it.

I have tested the power supplies in a test bench, the cables, video cards, ram, and the 3700x.

I don't think its possible to have gotten two bum motherboards, and both motherboards will operate q flash flawlessly.

Im at my wits end, my old pc died so i spent top dollar to replace and upgrade at the same time, and i feel like its gotta be something stupid i missed or something.

Edit to read components easier.
