Possible SATA Controller Failure on Z170-gaming 5 Motherboard

[Myles_3]

Alright, so, just built a new PC with:

Intel i7 6700K
GA-Z170X-Gaming 5 1151 motherboard
Nvidia GTA 1060 video card
Corsair 650W power source
A 1TB Western Digital HDD
and a Samsung DVD drive.

My issue is with the Sata controllers. At first, the hard drive was recognized but not the DVD drive. Switched around the data connectors, and now neither of them work. Anytime the computer turns on now it goes straight to the BIOS set up screen. Should be noted that there isn't even an operating system on it as of yet, and was going to use the DVD drive to add one, thus leading to this conundrum.

I guess my question is if there are any ways to reset the SATA controllers, or check to see if they're dead? Have reset the BIOS to default, switched out wires, and gone through every one of the SATA ports on the board. If you have any other pointers/possible solutions, feel free to chime in.

Thanks

Try resetting the CMOS by unplugging the PSU, removing the CMOS battery, then holding the PC power button for a minute or two. Then replace the battery and plug the PSU back in. Plug the HDD into port 0 and the DVD into port 1. Make sure the SATA power and data cables are firmly plugged into the drives. If the drives still aren't recognized, check the CPU socket for bent pins.
