Yeah like I said, I'm pretty sure there isnt a viable solution to this issue... I've been having issues like mad with my P6T Deluxe and Windows 7 combo. I'm not sure that its specifically Windows 7 but more mobo related. I love ASUS, they have been really good to me in the past... but jesus the issues are annoying.
Simple things like coming out of S3 will cause the system to hang resulting in a forced hard reboot... or leaving my external HDD plugged in will make the BIOS think I want to boot from that instead of my RAID set.

All with no forseeable solutions...
