Mac Book Pro Gfx card problem?

Hi everyone,

I have a macbook pro late 2007 model(Core 2 Duo 2.4 SantaRosa).

I was working all morning on it and everything was geat..no crashes no nothing.So, I had it switched off for a couple of hours cause i left home. When I came back i switched it on but it didnt show anything on the screen however i can feel it is working as i get the mac sound when pressing the power on button,the hard drive is active and a few shortcuts like the ctrl+option+apple+eject for shuting down work fine.It also recognizes my firewire sound card just fine and i get sound!!!By the way, the DVI display port doesnt work either when i connect a monitor!!

I tried with the power adapter on only , with the battery on only, with both on, i took out the memory and the battery and re-placed it back on but nothing different!!!!

So, is it that my Gfx card that has decided to stop working or is it something that i cant think and is very easy to fix??

Very desperate to sort it out as i have all my work in it and have to meet deadlines this month!!!

Thanks in advance

 

Thanks!!!I just spoke with apple and they will do it free of charge!!
They new straight away what it was!!
