The problem with that is only the 64bit 7 is running into this. XP, Vista, and the 32bit RC all remember the power settings while two of those are no longer on here. And this is about the 6th or 7th installation of the 64bit RC on different drives as well suggesting a slight problem with the original dvd burned.
Eventually I'll be upgrading out of this case entirely which would automatically rule out any hardware problems once the newer boards supporting USB 3.0 become available. By then I'll be running the retail 7 and shouldn't be seeing any of this then.
