I am not exactly the smartest with computers, therefore I watched a video on YouTube and now my Dell Inspiron N5040 doesn't boot after disassembling it and cleaning it with Dust Destroyer Compressed Air. I might of missed a couple of screws but I don't think that would matter. I took out the Hard Drive on accident, but I am pretty sure I put it back in place. I also took out the heat-sink, but I am pretty sure I put it back in place.
