Thank you Akshun. I think this was part of the problem. I took the CD out of the drive and it still didn't work. My sister advised me to take every flash drive and external hard drive off of the computer, which I did, and the computer came back up. Somewhere in the middle there I did the f10 thing to get to the BIOS menu. I changed a few things that looked like they needed changing, so that may have helped. I'm giving you kudos because you answered and went so far as to provide screen shots for me.
Thank you!
