Computer Lost Its Mind

If anybody's worried about me, quit it. I'm not sick; my computer is. It apparently "lost its mind" last Sunday and I've been trying to get it fixed ever since. The result is that I now have a computer with more memory (the same one, just more memory), an "empty" hard drive and a "slave" hard drive with all my old files on it. Since I'm an inveterate "backer-upper," I didn't lose anything important and even though it's still doing some strange things, it does work (mostly).
