dvd drive not detected in bios

[Jun Wei Goh]

hi guys i having this weird issue where my DVD drive will just randomly not detected by bios.Yesterday is was working fine but after i just unplug the fan 4 pin plug to clean my fan it not detected.
I tried update bios version,using cmos to reset, changing my sata cable with other device i have. Weirdly enough when i decided to plug back the sata cable that i though it failed works again.Then just yesterday it cant be detected again.
So is it the sata port itself or the cable i really dont know how to answer that. I tried connect to my other sata port same issue i doubt both of my sata port will fail at the same time right ? 

my dvd works fine can open close normally just cannot be detected on my computer
Anyone who know can tell me which is the root cause ? 
i was hoping is not the traces in the motherboard that crack causing this issue thx
i also notice when i plug the suspended cable my computer will hang at the post screen for about 10 sec or so then it boot to window .When i remove it , it will boot normally (about 3 sec)

Do you have a different pc you could try it in? If so put it in there and see if the drive itself is faulty, alternately it could just be a driver issue? Sorry for the basic ideas just saw that nobody had tried to help so i'm just suggesting the first things that come to mind.
