Obvious question in regards to this is does it show up in bios, and fortunately it does. So im guessing it is a software related issue.
Can't remember exactly the last time I used it though, but I know it was working less than a month ago.
Wouldn't care, i work with computers... but im clueless as to why it would randomly not show up unless it was broke. needless to say if its all connected as bios detects it. Had this homebuilt PC for over 3 years and never an issue until now.. (I guess i can put my warranty to 3 years) lol.
