Hello, I'm having trouble with my computer/display monitor. Few hours ago everything was fine. I was cleaning the inside a bit, turned it on and...my screen wasnt displaying anything. Checked for lose cable, and everything was fine. Restarted it, and same thing nothing. I put on my headphones and turned the computer on and heard a beep and that was it. As well my keyboard lights up when I boot it up normally, but when the problem occured it doesn't up light up anymore. Any suggestions? Please.
I suggest you check those connections again. You might have dislodged the video card or you might have shorted-out the motherboard or generated static electricity that destroyed the motherboard and/or video card. How did you "clean" the computer?
