Hi there,
I know the feeling when you can hear the pc boot and you can't see anything or you can't access your data.
I've seen it on a dozen of laptops and desktops.
I allready gave a solution on another thread, the question is: are you going to have it done or do it yourself ?
Today I repaired a laptop which went blank after 10 minutes, it took me (expert) 4hours with great results.
I charched 40€/h.
The reason behind these laptops going bad is because of the GPU behind fixed on the motherboard with lousy soldering !
I repair them by just heating the GPU to 195°C and that's it.
The only way to do it is the way I explained on this thread:

look also at the video of someone doing it. (the only thing he's doing wrong is the temperature, I keep a sensor close to the gpu and measure it closely)
good luck.
cheers, Louise.
