Hi! When I returned to my room today after having washed some clothes, I was more than a little surprised to find that my Macbook wouldn't take my admin password to unlock the screensaver. After several tries of careful typing, I figured I'd just have to give it a cold restart. I was even more surprised when I upon said restart found the Apple logo after the "bong" to flicker between the apple, a prohibitory sign and sometimes a question mark. A quick look at Apples KB makes it seem like a software problem which could be solved by booting from the OSX-DVD, but I'd like to ask here as well if there's anyone who's had any similiar experiences.
