My motherboard BIOS refuses to recognize my optical drive, hdd, and SSD. I have double checked to make sure that that SSD sata cable is connected to the 6gb/s slot on the motherboard and that the sata power connector and sata cable are secure on all three components. There could also be a problem with the sata power connector. Besides this, the psu and motherboard are working fine. I would also like to add that this is my first time building without prior experience in building computers. In addition I have the ASUS z170 pro gaming. Thank you
