Did you change any settings recently, or install something new?
Maybe see if you have fast boot enabled?
Yes so just turn it off for a while and see if this still happensFast Boot has been enabled from Day 1 and I've always gotten a POST beep and Asus splash screen, so that would be the cause of this odd behavior. And today I got the POST beep but no splash screen! So odd.
