Computer problem

[DrunkMexican]

My computer has been acting stupid after I went on vacation and my family used it while I was gone...

The problem is my computer turns on but shows nothing on the monitor. I tried swapping out the monitor but no luck. Also now when I turn it on it turns off then it turns on again on it's own.

Help aq
