  • We're missing some details here like Mac Model (iMac or Macbook Pro) what version of the OS are you running? Have you tried Verbose Mode (Cmd-V while turning on)? Remember, we're not there to look over your shoulder so the more relevant details the better. – Allan Feb 28 '17 at 22:36
  • The os version is yosimite when I try verbose mode so far the screen appears as it should black with white text then the screen goes conpletely grey – Katie Bonnici Mar 1 '17 at 1:50
  • Couple things to do...while booting in Verbose mode, see if there are any errors that appear; use a cell phone camera to catch everything. Secondly, run Apple Hardware Test (AHT). Hold the D key while booting from a powered off state with the AC adapter connected. – Allan Mar 1 '17 at 12:03
  • I video taped the verbose mode and there was no error them the screen turned grey and when I turn it on holding d the screen turns on grey and stays grey – Katie Bonnici Mar 2 '17 at 23:21
