I've tried various ways of loading Apple Hardware Test on Mountain Lion as descibed by Apple:

https://support.apple.com/kb/ht1509

 

Using a wired keyboard and with every thing else un-plugged I tried

Holding D at bootup

Option+D with WiFi on at bootup

Both ways failed.

 

Then I tried using my iMac's original Leopard DVD that has AHT on it. While it seems like its loading the mac  dies before it actually loads !

I did that twice and both times mac died before AHT could be loaded- like some one yanked the powercord out.

 

How am I suppose to load AHT ?

 

 

I upgraded from Snow Leopard to Mountain Lion on a 2009 iMac.

 

Thanks
