MBP Not Recognizing Any Display Neither Internal Graphic Card

Question

Hi Guys:
Here's the problem, i got a MacBook Pro 15.4" 2.4 Ghz Intel Core 2 Duo, 2 GB Ram (Late 2007)(specs http://support.apple.com/kb/SP13), and i was using it and everything went perfectly normal, last night i turned off with the DVI to VGA adapter connected, cause sometimes i use it to see movies in the Projector, this morning i tried to turned on, (still the adapter connected),  and the display never turned on, stayed all black and not sent image to any external display. I Have tried everything, i know it's probably just asoftware thing cause i can acces it thru screen sharing with my other computer, I have tried reseting the PRam, put it on target mode, starting it with the Snow Leopard Original disc by pressing C, etc. then i access it again thru screeen sharing and i went to system profiler, and there in the Graphics/Display Section it tells me that my VRAM is 64 mb and that it's shared with the System memory, but thats not true this computer came with an NVIDIA GeForce 8600M GT with 256MB of GDDR3 SDRAM and dual-link DVI wich is not shared and obiously not 64 mb, i'm trying to figure out if it's a hardware failure or a software failure, and if it is hardware what do i need to replace.
I left a picture of the system profiler taken thru screen sharing so you guys can see what i'm talking about.
Hopefully somebody  will know what to do.
As Always Thanks Very very much!!
I'm Running MacOS 10.6.8, 160 GB HD, 15.4" TFT and 2GB RAM, all factory settings except for the glossy display.

OK!! I found the problem, the thing is now an issue of guaranty, it seems that this particular model of graphic card (NVIDIA GeForce 8600M GT with 256MB of GDDR3 SDRAM), comes with a factory faulty processor, so Apple has granted a replacement program for all the mother board within four years of the original date of purchase, and here comes the problem, i bought my computer in November of 2004 and the problem came in early december, still it's a factory issue, i never did anything wrong with my computer, it was working fine, one morning simply didn't turned on the display, so now im supossed to throw it to the trash can?? i can't afford a newer Mac if were i already had a new one and i wouldn't be working with a four year old computer, but I have to it's my work i eat from there, so... now that you now my pathetic position, ¿What in the world can i do?, is there a way to talk Apple into changing my mother board, cause they have the exchange program running right now, my computer jus took a bit longer to fail, but i'ts having the exact problem they describe here:  http://support.apple.com/kb/ts2377
It's factory faulty and i have the exact graphic card, as far as I have searched there's an air bubble in the graphic processor, wich leads to an overheating, so if there's anyone who can help me it will be much apreciated.
Thanks again
