Dell :: M1710 Graphics Card Dead, Help

I was playing GRID on my Dell XPS M1710, and got a load of corruption and lines on the screen, and the laptop shut went into a kind of safe mode. It has never been overclocked, and dust has been cleaned recently.

Now, when I turn it on, I get artifacts and corruption even at the BIOS screen. I've tried reseating and reinstalling the drivers, but it hasn't worked. I'm going to call dell tomorrow, but as it's out of warranty,

I don't expect much help. There's no way I'm buying a new GPU, (they cost more than the laptop is worth), so I'm going to try and fix it. I'm going to use the oven fix as a last resort,

and would appreciate advice on anything else I can do to fix it, as well as any tips when performing the oven trick. If anyone is selling a 7900GTX/7950GTX for a decent price, you may have a buyer
