My computer recently shutoff completely and when I tried to restart I was getting error messages about not finding Windows system32 files. Thinking the Hard drive was gone; I went and bought a new Sata hard drive and continued to have the same problem and the drive was not listed in any of the Bios settings nor in the boot up. I had installed the Data Lifeguard tools (western Digital) and even it did not detect my hard drive. I have recently tested an IDE hard drive and it worked perfectly on the machine. I dont know if my sata controllers on the mobo are broke or if im failing to load something. So basically I have 2 Sata hard drives that are not found on the computer (1 with windows loaded that had worked perfectly, 1 clean) and can not seem to get any further progress on fixing this comp. Any help on resolving the issue would be greatly appreciated.
