I am trying to help my friend setup his computer all his parts are factory new, except 2 hard drives, he has a 500GB SSD also, he as installed everything and the computer boots to BIOS without problems, but when he goes to BIOS no hard drives or SSD is shown, None of the 3 hard drives are detected, we have tried:
Clearing the CMOS
Changing the SATA Mode Selection to AHCI
Loading the Default UEFI Settings

Any suggestions?
The Motherboard, Processor, RAM, and 500gb SSD are all brand new, but none of the 3 SSD's are detected.

Please help Urgently!
