My system is different than yours--see my profile--but I was experiencing the exact issue you are having after the 2nd boot from USB. Well, this problem disappeared as soon as I reflashed my MB with the latest BIO from Gigabyte. You might give that a try.
If anyone is interested, the HIS 6870 worked flawlessly OOB!
