Hallo ,I have an IMAC 21.5. which does not start.When i press the power button i hear only beep with an interval of 4-5 seconds.Some times when i take off the RAMS and put them again then get a white screen and shows that i have to insert a bootable device.Then i bought OSX mountainlion on line and wrote it on a DVD and tried with a USB key board to start the DVD.But does not work.Please help me to get this imac work.

Thankyou in advance  for your help.


iMac, Mac OS X (10.7.5), I am not sure the OS bought in 2012
