Q: Imac diagnostics will not start in Mavericks

Hard drive is clicking at start up sometimes and when I come back to my Mac after it goes to sleep, sometimes I can't get a login screen. I have to manually reboot at times.


OS 10.9.5 Mavericks

Processor 2.66 GHz Intel Core I5

Memory 4 GB 1067 MHz DDR3

 

I'm thinking hard drive failure but can't get to the hardware diagnostics at start up.


Any help greatly appreciated.
