I have a dell inspiron 9100 with windows xp home and i was having this problem with my screen being blank when i booted it, you could hear the hard drive making noises but the screen was blank. The screen would eventually come on after waiting a while and rebooting a few times. Now the screen will not turn on at all, i've checked the lid close button and that isnt stuck. My only thoughts are that its the video card, but im just hoping it isnt. If anyone has any thoughts let me know.
