Everything seems to be connected appropriately. Upon powerup, the post reporter reports that the hard drive could not be found. When I go into bios, it is not there, but once I auto detect it, it shows up. I just finished putting this computer together, and this seems to be the only problem that I am having. I already tried using a different ribbon for the hd. It is the only hd, so I have it set to master, and the cd rom is set to secondary master. Any help would be appreciated.
