To tell it in another way : it s a hoax, a bug !! This FAILURE is not from your hardware but from the test itself. How can an apple certified test can deliver the EFI test PASSED with a deficient INTEL HD 3000 and deliver OS test FAILED with a fake ERROR 72, 73 and 74. The acceleration seems to work perfectly from tv, streaming, and the test itself. I am selling all this to go back to PC again.
