I have this laptop and when i press the power button, the screen turns on, I see the Dell logo briefly, then it's just black. No windows logo or anything. I also can't seem to hear anything coming from the computer. No fan, no sound from the hard drive, nothing just a black screen. I'm not super tech savvy, and don't have the funds to take it into a shop. Any suggestions on what I might be able to do well be great.
