Hello Guys,

I have dell inspiron n5010. 3 days ago i changed hard drive of my laptop. But now i am facing one problem with my laptop. Recently i start my laptop. But screen of my laptop is showing black. Someone please let me know what is the problem.

Is there problem with hard drive or have other software/hardware problem.

It isn't usually the motherboard that is the cause for a screen not working. I can be the ribbon cable that connects the display to the laptop. I can be the display itself that is going, or it could be the graphics card.

Try this. Turn off the laptop, connect an external monitor, turn on the external monitor and then turn on the laptop. Can you see anything on the external monitor? If yes, then you need to check that ribbon cable, and if that is fine, then look into replacing the display.

If you can't see anything even on the external monitor, then it is your graphics card that is a problem.
