I recently tried to help fix a friend's computer. He had just built it but it was never operational. With some troubleshooting, I managed to boot to the BIOS. At that point, I looked at SATA connections and it recognized the DVD drive but not the HDD. The DVD drive would light up but wouldn't attempt to open and wouldn't read discs when I put one in (using paperclip to open drive). I never did get it to recognized the HDD either...I tried using different SATA ports and a different cable. It could be that the motherboard was damaged when he tried to put it together himself. Any ideas?
