My son bought this mb and started building last night. I have never used any sata devices before. He bought a new DVD sata drive, but bought a converter for his current ide HD. The computer starts up weird. It powers on then sounds like its turning off, but then starts up again. I get a message to insert boot media and to hit a key. When I go into the bios, it is not recognizing the HD at all. I think it's recognizing the cd, but when I click on the device it says disabled. What am I doing wrong????
