My 3 year old flipped my Dell Studio laptop over onto the carpet. It didn't land very hard, but something was jarred during the event. Now it will not boot to splash screen and can't get to any boot sectors to try to diagnose. I just get a blue screen that does have backlight it looks kinda pixely at the top when I first start the computer. I can dim and brighten the screen. A couple of times I saw the windows logo flash on the screen for a second and heard the windows logon theme. I have unseated and reseated the memory cards, removed and put back the hard drive checks all cables and anything that could be loose. I also tried connecting to my tv via HDMI but it doesn't work. Any ideas? I have a new motherboard, I don't think its that. I also don't think its the hard drive. To me it seems there is a loose connection or wire? Any ideas? Could it be the screen?
