Ok I have an update about this mess. The first thing that I did was the Lion Recovery (which is holding down Command + R while startup). Next I selected the option to put a new Lion in and after waiting for what seemed like a few hours, it restarted (as it should) and it brought me to the dark grey screen which features the option to choose either my username or the admin. Once I clicked on my username, it did nothing. (Don't know why Apple would put that in there in my opinion, but moving on.) Then, I restarted my laptop again, but this time I held down the Shift and "fn" buttons. This brought to me the dark grey screen but it gave the two lines of space to type in my username and my password. As a result of all of this, I can access the Internet except for websites like YouTube and any other website that has a video player. I can access my school documents and the Mail app (since I'm currently a student).
Yet, I still have no sound!! One more thing, when I went into my Launchpad, it went through some crazy motion and I thought everything was going to be gone.
I would love to go to an Apple Retail store, but from where I live, its about good 45 minute drive. The nearest store near my place of residence is in New Haven, CT. I would also would love to go to my Tech Support Team at school, but they don't work on the weekends.
Does anybody know how to fix this?
