Hello, I have been trying to get windows 7 Ultimate 64 bit installed onto a raid I created with two ocz agility 3 ssds. Everytime I try loading the drivers at install it gives me an error stating the drivers are unsigned and to install a 32 bit OS. When installing a 32 but OS, the install works normal and the computer runs fine. I am just wondering why it wont install for 64 bit considering I would much rather run 64 bit. I went to both the MoBo's website and the main companys website for the chipset drivers (AMD) but have both turned up with the same error. Any thoughts as to why ?
