Yeah! Before we get to the BIOS I want you to look at two pages. The first is listed as 1-4 (p.13 according to your PDF reader) and it has a drawing of your motherboard. On the lower right hand side it lists and numbers your SATA ports. Please tell me what port numbers you have already tried. Then go to 2-7 (p.21 per your PDF). According to the drawing what configuration do you have your memory set as? Edit Update: I have done further research and one thing I have learned is that your experiences with the SATA ports could be due to an inadequate power supply. To be honest I have always been suspect of the one you have in terms of qiuality power output. But we have to determine first if your SATA is enabled in the BIOS. This is important. By the way, since you only have one harddrive it doesn't matter what SATA port you choose. It just needs to be enabled.
