I don't know if this is the correct area to send this question. It is kind of an odd one, but here goes.
I am trying to figure out a way to lock my computer's hard drive, or make it shut off every 5 minutes, or something to make my computer appear broken. I have a person that I don't want to be able to use it, and they are not very computer literate, I am looking for an easy way to make it look like it is not working. Then I would like to be able to make it work again, when need be. Any suggestions? Thanks.
