If you use COMMAND + V you will  boot in verbose mode. I suspect you will see errors reading the hard drive repeated, this would indicate SATA or Hard Drive. Since both are used to store the downloaded Internet Recovery it would be effected.

You should get a thumbdrive as Dan suggests to isolate that set of devices from the boot process.

You could also hold down D and see if diagnostics come up.  If so run the tests.
