|Changing the board (must be the exact model version, etc), trying in a different computer with different wire sets is worth trying, but if the BIOS will not detect the drive at all, then you are at a dead end by your self. If it is detected in the BIOS, then you have a chance. If your BIOS detects, it then look in Disk Manager and report if/what it shows up in there as. Otherwise, the pros are your only other choice if the data is important enough to spend the money on recovering it (I do not believe that the fee has any guaranty as to if and how much will be recovered).|
You have to be a little bit crazy to keep you from going insane.
