Asus AV8 doesn't see sata drive

[HotWire]

I can get my hands on a Asus A8R-MX/S to replace my AV8 deluxe that doesn't want to see my sata drive anymore....put in a new 200 Gig sata drive and the system is still giving me a blue screen and windows error message. Question is the Asus A*R-MX/S worth the $99 my supplier is asking for it?
