Imac 24 aluminum - apple hardware test using wireless keyboard

Question

The manual that came with my imac describes the steps to run the apple hardware test as follows:
1. disconnect all external devices, except keyboard and mouse
2. restart mac holding the 'd' key
The apple hardware chooser should appear next.
When I do these steps it goes right to my desktop every time. I am running a mac wireless keyboard and mac mighty mouse.
Anyone have an idea how I can get the Apple Hardware Test up?
Thanks.

Hi,
It can take a few minutes for the AHT to appear after booting, D key, etc:

Try shutting down your iMac, reboot and THEN do the AHT.
Are you able to boot from the restore disk?
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
