There can be many reasons for this. Check to make sure all the cables are
securely in place for all your installed drives. Even if one of the cables
is slightly loose from one of the devices, slightly enough to even avoid
detection, it can cause this type of problem. Make sure that the cables are
connected properly (red strip on cable is connected to Pin1).
On a more sour note, if you touched a part of the motherboard and weren't
properly grounded, you may have burnt the board. Since the drive works on
another computer then that isn't the problem. Also, be sure that the RAM is
seated securely and also if the RAM is compatible with the motherboard.
Something may have popped loose while you were playing around in there. It
has happened to me more than once. If nothing seems to work after you have
checked everything, you may want to bring it into a shop and check if the
motherboard is ok. It is possible that it is defective.
