just got on my desktop for the first time in a week or better and for the last hour and a half I have been trying to figure out why it is not seen any of my serial ATA drives??

This is the 1 TB drive the 500 GB drive and my DVD light scribe burner, after running down everything going through all of this leads and everything have come to the conclusion that the serial ATA controller for the motherboard has died it no longer lists my serial ATA drives and the hardware directory nor does it see them in CMOS yes they do have power this just means that is going to be sooner now then later for me to upgrade my motherboard I was hoping at least it would wait until I had my laptop paid off, this does mean that I will have to be buying a new motherboard and processor memory and a few other odds and ends most likely hopefully I can still use my video cards and so I can get better once, it is a great thing though I do have a back up laptop.

I am pretty sure that is all the problem is and the drives will come back online when I redo my motherboard, crossing all fingers and toes though on that 500 gig hard drive there's almost 200 gigs of it that is music and a little over 100 gigs that is artwork that I have collected over the years I do have a backup of my music onto my laptop and most of the artwork, tomorrow morning I will be pulling desktop apart and checking to see if there's any loose connections or anything but I am pretty sure that the controller has gone out in it as on this particular motherboard it's a first-generation serial ATA controller for the earlier serial ATA drives.

Now here I go off looking for a new motherboard I will be replacing this one though with an AMD AM3+ DDR3 motherboard memory and processor.
