Asus n56vz errorcode 8877652

[iSnob]

Hi,i have an asus n56vz,with mavericks 10.9.2 until recently everything worked.
But for a problem I had to flash the eeprom (bad bios update and corrupted bios)
Now have the same bios and setting where everything worked with osx.

But now the boot is very slow and return this error:

 

 

 

DRMStatus: iTunes/Apple Store Content Access Problem. Content playback may be disabled on this computer. You can Continue to use the machine, but you should contact an Apple support representative. ErrorCode: 8877652

And now the hd4000 is recognized,but no accelleration,
 

someone help me?
