Sorry to say your GPU has failed. The best thing you can do is replace the logic board or if you can find someone with micro-soldering skills see if they can save your logic board. Most of the time the internal flip chip construction has failed within the GPU so you really need to replace it.
The rub here is finding a new Vs used chip is just impossible to find any more as this chip had a lot of failures. many people replaced their 2011 with the newer 2012 board but even that is getting hard to do for the same reason the demand is stripping out the available parts ;-{

Sounds bad, Is it possible that both GPs are dead or just one? and how is it possible to check which?
If you can start up your system in safe mode or Target Disk Mode that is the best way to isolate the intergraded graphics services within the Intel CPU. It takes some doing you might be able to remove the dedicated GPU drivers so the integrated is running but that will create other issues.
