You may have a cold solder connection on your motherboard.  That can sometimes be fixed by heating the motherboard in an oven or with a heat gun.  Of course before you do that all cables and parts that can melt must be removed.  You can see a youtube video of how here, http://www.youtube.com/watch?v=jsmlALfEgPg

I  have two Dell Latitude D630 laptops running Vista Business and one  
D620 running XP. All three were in my to be scrapped  pile  because I 
couldn't get a video image either on the laptop or on an  external 
monitor. Maybe I'd get an image one out of 10 tries (turn  on) if at all. 
It appears the backlight is on, and the computer  seems to be running. I 
have tried all the things I can think of,  including replacing memory, 
HDD and with and without battery. I gave  them one last chance before 
parting them out and lo and behold, now  they seem to work reliably.
Sure looks like a GPU chip, but I would  expect them to die completely. 
Maybe they were just tired and needed  a rest!
Any ideas of what's going on?
