There are many things that can go wrong on your computer, I'm assuming it was shipped. The hard drive has moving parts so it would be easy to break something. In the past I've seen Ibuypower use Asus motherboard or other top notch brands. But it's still possible it's a sata controller that's your problem. It could also be a issue with windows cd you have, or even the DVD ROM. The possibilities are endless, but my gut says it's the hard drive.
