Good evening!
Let me first explain my predicament. I recently upgraded to a brand new PC, and began from scratch hardware-wise.

I have an Intel SSD PCIE 3 as a boot drive (works fine), a too expensive M2 drive for apps and another normal SSD connected to 6 GB SATA port 5.

I connected a Seagate Barracuda 3 TB to the SATA port 6 and another SSD to SATA port 3. The problem is that they don't show up in BIOS. I have updated my drivers for SATA (Intel and some ASMedia stuff), and my BIOS is updated to the latest version. Still no dice. I've tried to swap cables and try different SATA ports, but to no avail.

Is there some esoteric trick I have missed or something obvious in that using the PCIe lanes makes using SATA impossible?
Any help would be appreciated. My BIOS says the SATA ports are "Empty".

Yeah, it's port 1 and 2, so I have stayed away from those. What I am wondering is if the PCIe drive "kills" off some SATA ports. The chances I have two faulty drives are slim, as I see it.

What I find strange, is that one SATA port obviously is working and so is the SSD connected to it. Would you recommend flashing the BIOS to see if it helps? The other two drives are connected to the same power cable (my PSU is a Corsair AX 760W).

The only two possibilities in BIOS for setting the SATA ports are AHCI and RAID. They are set to AHCI. I am really at loss about what to do.
Installing a hard drive should be among the simplest things to do on a motherboard.

I pulled my CMOS battery out and all power cables in an attempt to get a fresh start. Will report the results.
I have checked all cables, and basically done everything I can think of. Google tells me no other person on Earth is having the same issues, so I feel special and not in the good way.
