I just noticed this and I really don't know how long its been happening because when I turn on the PC every morning I usually walk away(start coffee, use bathroom). But the other day I noticed that there was an additional Post beep, looked over and noticed that it was booting again when I know I already saw the POST screen. What I noticed is the part of post where it says UPDATED ESCD.......Success. Which is kind of weird considering I haven't added hardware or changed any BIOS setting. Since then I noticed it does this every morning on boot(sometimes even twice). It will do the UPDATED ESCD...SUCCESS and then reboot. After the normal ESCD it will continue to boot into Vista with no problem.
It may be one of my BIOS setting but I don't know how long its actually been doing this so I can't be sure. Something I'll have to look into when I get a minute. Other than that this board has been exceptional and I have been gaming my butt off since I got it so haven't done anything since the initial OC to 3.4.
Anybody else notice this?
