Ok here is the problem, i gutted my brothers hp and put all the components in a shiny new tower and added a new power supply and graphics card. Motherboard, cpu, cd drive, and harddrive didnt change. When i start it up and it runs through the ide test all the computer see's is the harddrive. The cd-drive gets power and i switched out the data cable with a known good one. Still doesnt detect it. The motherboard is a ASUS P5LP-LE. Im really at a loss here. Can anyone lend the expertise?
