Q: Will not install from dvd

My Intel iMac bought in 2011 suddenly crashed and now will  not restart.  I get a grey screen with the apple logo with a whirly which is as far as it gets.  I have tried holding down the shift key on startup but that eventually takes me to a blank blue screen.  I tried resetting the pram to no avail.  I tried the unplugging for 15 seconds also to no avail.  I then tried loading the install OS 10.6 DVD but the screen goes blank and then there are 3 hoots, like a boing, which repeat regularly every few seconds.  Oh, I also tried removing and pushing back the ram chips in case there was a loose connection.  I have / had tried disconnecting all peripherals including with and without the usb keyboard and mouse

 

Poor me, the machine is exactly 6 weeks out of warranty! 

 

Can anyone help or seen this before?

iMac, Mac OS X (10.6)
