Computer ghosts

I think I have a ghost in my computer. It won't boot up every time I turn it on. I have to talk to it, curse at it, and now I even do rituals to see if it will turn on. I tried computer software repairs, took it to the local computer repair store and the same thing happens. It works for them but when I get it home. It plays the maybe I'll boot up maybe I won't game with me. I got fed up and bought a emachine. A small desktop computer. I got it hooked up and it worked fine. I had to try the old computer just to see if it would boot up. It did. I tried it again and it booted. In fact the problem seems to be solved. Maybe I made the old computer jealous. Do you have computer problems or a ghost in your computer?
