I was given a pc (asus K8N-E) the problem is that although it powers up, mobo light works cpu fan spins and system fan spins front panel lights work, the hard drive and optical drive wont power up unless i disconnect the IDE cables, when disconnected the hard drive spins and the light on and drawer on the optical drive work. its as if the IDE is somehow disabled, i have tried different cables but to no avail any help appreciated.
