Hello,

I installed this motherboard and I get a very strange issue. When I turn on my computer, it prints multiple Q_codes before getting to A2 then nothing happens. This is when I connect ma SSD and my HDD to the motherboard. If I disconnect the SSD, it blocks on A3, then nothing happens.
In both cases, my screen remains black (no signal I guess).
