Hello. I have recently purchased a custom-built pc, retaining cd/rw &dvd rws , plus both hard drives.Iam finding I can't boot the machine normally and have to use the windows CD (XP he) to get it up and running. The mobr is an A8n SLI board which supports the later sata hard-drives .Is it probable that this is the reason it won't boot normally ?...do i need maybe ide controllers or whatever they are called , and if so where do i get them from ?
