First hook it up to an external monitor to confirm that it is the GPU. These can often be reflowed with a hot air work station. I have had about a 70% success rate doing this. There are also repair services offered on eBay. Compare prices on a repair vs replacement and be sure they have a good warranty.

@rany may also be doing this service now and shipping would be cheap on just the card.

@refectio may also be doing it.
