My computer turns on but nothing appears on the screen?

My computer turns on automatically when plugged in but nothing shows up on screen. possible problems?

At first my computer would not turn on.. I took it to a friend who replaced the power supply and it worked for a short while before it started with new problems. Now i can't get it to turn off.. It turns on automatically when plugged in and nothing will show on the screen.. I don't know what the problem could be. Any thoughts?
Answer:

Well the same thing happened to my laptop.I would take it to a place that works on computers. Professional help is always good when it comes to things like this.It could also mean you have a virus of some type hidden in your computers hard drive or something. I hope I helped the best way i could!!
