Did you reset the BIOS to defaults? Then what is the SATA controller setting now?
Does the hard drive show up in BIOS setup under Storage, IDE/SATA devices or Boot Order priority?
Did you run the HD and RAM tests? Will these boot either?
Did you try a new Win7 installer? Does the one you have boot in another PC and proceed normally to see the HD on drive selection screen?
Yes BIOS defaults were loaded using F9 (American Megatrends, Inc.) SATA controller lists AHCI.
The Hard Drive does show up in the BIOS and lists the port SATA5. The Hard Drive is listed as the first boot device.
I took your advice about not using USB sticks and went out to best buy and bought DVD-Rs and burned the Memtest iso. It works on a stable PC but not on the PC in question; instead it flickers the interface for a fraction of a second then immediately restarts.
As far as a "new" Windows 7 installer I downloaded from Windows 7 Direct Download Links, Official Disk Images from Digital River
