My Mac was shipped with Lion. Therefore I have no install CDs that I could use to run a hardware test.
How can I run a hardware test?

Best Answer
If your mac shipped with Lion, you should be able to run the hardware test by simply holding D when your computer boots.
If your mac did not ship with lion, you will need the original install disks to boot into the hardware test mode.
