I have a problem with my motherboard. The SATA disks I have installed appear properly in the BIOS menu, but when I want to install any Windows OS (Vista, XP), a mesage appears saying that the disks are not recognised. The BIOS version is 0904 and my SATA disks are seagate ST3500320AS sata II. The RAM's that I'm using are Mushkin PC3-14400 and the CPU is Intel Q9450. Any suggestions would be more then appreciated.
