Fired up my new build yesterday and everything seemed to go nicely. However upon reviewing the Bios settings the DVD/CD drive did not show, nor did one of my SSD's. CPU, RAM, SSD all were normal.
Just to be sure, it sounds like you have 2 or more SSDs in the computer since you indicate "one of my SSDs."
It sounds like you've done a good deal of troubleshooting, but to be sure:
- Remove everything from the computer with the exception of the mobo, CPU, PSU, GPU and RAM - literally take everything else out, including the cables. You should be able to get a basic POST with these items. If true, then move on to the next part (NOTE: you should reduce you RAM to one stick, perform this test, then insert all your RAM and perform this test again)
- Let's start with the ODD. Attach the ODD to the first SATA connection (add a power plug) and boot up the computer. Does the ODD show? If it does, move to the next step. If not, remove the ODD and put in the known good ODD. Now, does that one show? If the known good one shows, then the first ODD is bad. If neither show, then swap out the cable. Still doesn't show, then it could be the mobo. Before you RMA, search the web to using a search similar to THIS ONE. Play around with the wording, but you might find a solution this way.
- Assuming the computer is able to recognize the ODD, do the same as above with both SSDs. Same process as above: remove the ODD, insert SSD into the same SATA connector.
- Assuming the computer is able to recognize the SSDs, you have now verified (a) the first SATA connector is good and (b) your ODDs and SSDs can be recognized.
- Using the ODD, repeat the same process as in the second bullet, but with each SATA connection. If any SATA connector does NOT recognize the ODD, switch to an SSD and verify it is not recognized either. At this point, you're looking at a bad connector on the mobo and the mobo should be RMA'd
- Assuming all SATA connectors work properly, begin populating the SATA connectors (starting with SATA0), in order with your SATA devices (SATA0 - SSD1; SATA1 - SSD2; SATA2 - ODD). If possible, use 3 known good SATA cables. See if all three show in the POST. If they DON'T, move the SATA cables around to verify it is not the cables. If you still DON'T see them, then you could be looking at a PSU issue. Swap out the PSU with a known good one. If swapping out the PSU does not yield any results, then you're looking at a bad mobo again.
Based on your comments, my first thought is a faulty mobo; second is the PSU. Give this a try and let us know what happens.
Hope this helps.
