The problem is I'm not exactly sure how to do that. A friend told me to just hit the F10 key on startup. I tried it, and it failed. After some research I came to the conclusion that this does not work on a Dell but only on certain brands like Hp and others. In further research it seemed like the answer would be to hit Ctrl + F11 on startup. I tried this and it didn't work either.
I'm not sure if I'm either pressing it at the wrong time or if the computer is too old and this function was not included on earlier Dells.
If someone could tell me how to restore the computer to factory settings and start clean please let me know. Any way of doing this is appreciated.
